Breast Cancer Case Study

A breast cancer case study presents a fictional patient scenario that allows nursing students to apply theory to practice. By following one patient from presentation through diagnosis, treatment, and follow‑up, students develop a deeper understanding of breast cancer assessment, nursing diagnoses, care planning, communication, and patient education. Breast cancer is the most common cancer among women worldwide[1], and early detection and comprehensive care can improve survival[2]. In this case, readers will learn to identify risk factors, interpret diagnostic results, anticipate nursing problems, and provide holistic care. Phrases such as “in this case,” “the nurse should,” and “from a nursing perspective” are used throughout to emphasize a student‑centred viewpoint.

Patient Profile

Patient initials: Mrs. A
Age: 48 years
Gender: Female
Occupation: Elementary school teacher
Marital/family status: Married with two teenage children; primary caregiver for her elderly mother
Presenting complaint: Painless lump in the upper outer quadrant of the left breast noticed six weeks ago
Past medical history: Mild hypertension controlled with amlodipine; no previous surgeries
Medication history: Amlodipine 5 mg once daily; occasional ibuprofen for headaches
Allergies: None known
Reproductive history: Menarche at age 12, first full‑term pregnancy at 32, two children, breastfed both for six months; still menstruating regularly
Family history of cancer: Maternal aunt diagnosed with breast cancer at 55; paternal grandmother died of ovarian cancer; no known BRCA testing in family
Lifestyle factors: BMI 27 kg/m² (overweight), exercises infrequently, drinks wine socially (3–4 glasses/week), does not smoke
Cultural/social factors: Lives in an urban area but comes from a close‑knit rural community. She believes in natural remedies and initially delayed seeking care due to fear of a cancer diagnosis and responsibilities at work and home. Her husband provides emotional support but is worried about finances and the impact on family life.

Specific diagnosis: Stage II invasive ductal carcinoma (IDC) of the left breast, estrogen receptor (ER) positive, progesterone receptor (PR) positive, human epidermal growth factor receptor 2 (HER2) negative. IDC is the most common type of breast cancer, accounting for about 80 % of cases[3], and Stage II indicates either a small tumour with metastasis to one to three lymph nodes or a larger tumour without nodal involvement[4]. Hormone receptor‑positive cancers usually respond to endocrine therapies[5].

Presenting Complaint and History of Present Illness

Mrs. A reports discovering a small, painless lump in her left breast while showering. At first, she dismissed it as hormonal changes. Over the next few weeks, the lump persisted and she began to feel intermittent heaviness and mild discomfort. She experienced no nipple discharge, but noticed slight dimpling of the overlying skin. Her anxiety increased as she recalled her aunt’s experience with breast cancer. She delayed seeking medical care because of fear, busy school schedules, and responsibility for her mother. Eventually, she confided in a colleague who encouraged her to see her primary care provider. She expresses worry about the impact of a cancer diagnosis on her children and the cost of treatment.

Nursing Assessment

Subjective Data

Pain and sensations: A reports a painless lump with occasional mild discomfort (pain 2/10). She denies burning or stabbing pain.
Emotional response: She verbalises fear of cancer, concern for her family’s future, and embarrassment at having waited to seek care. She repeatedly asks whether the lump could be benign.
Knowledge and beliefs: She has limited understanding of breast cancer and believes that injury or stress may have caused the lump. She is unsure what mammograms or biopsies involve and worries about disfigurement.
Family concerns: A is anxious about her children’s reaction and the possibility of needing to stop working. She worries about who will care for her mother during treatment.
Support system: She identifies her husband and close friend as sources of emotional support but anticipates needing help with household tasks.

Objective Data

Vital signs: Blood pressure 136/82 mm Hg, heart rate 82 beats/min, respirations 18 breaths/min, temperature 36.8 °C, oxygen saturation 98 % on room air.
General appearance: Alert, appropriately dressed, slightly anxious facial expression. No cachexia or visible distress.
Breast examination: Inspection reveals a 2.5‑cm firm, non‑tender mass in the upper outer quadrant of the left breast with slight skin dimpling. The nipple is not retracted and there is no discharge. Palpation confirms a mobile mass with irregular edges. No palpable masses in the right breast. Left axillary lymph nodes are mildly enlarged and tender; right axilla is normal.
Pain score: Rates lump discomfort as 2/10 on the numeric pain scale.
Skin findings: Intact skin except for slight dimpling over the tumour; no rash or ulceration.
Lymph nodes: Left axillary nodes palpable (1–1.5 cm), non‑matted; supraclavicular nodes not palpable.
Psychological observations: Eyes tearful at times, occasionally fidgeting. Expresses worry about body image and intimacy.
Relevant risk factors: Age > 45, overweight, late first pregnancy, limited breastfeeding, family history of breast and ovarian cancer, and physical inactivity. These factors are associated with increased breast cancer risk[6].

Psychosocial Assessment

Mrs. A shows signs of anxiety related to the diagnostic uncertainty. She worries about changes to her body image and sexual relationship with her husband. Financial stress is evident as she is uncertain about insurance coverage and time off work. She feels guilty for delaying care and fears telling her children. Cultural beliefs about natural healing make her hesitant about surgery and chemotherapy. She expresses a need for counselling and information about support groups.

Diagnostic Investigations

Early detection and accurate diagnosis are critical to reducing mortality[2]. The following investigations were ordered for Mrs. A, and the nurse plays a key role in preparing the patient, providing education, and monitoring for complications.

Investigation	Nurse’s Role	Findings
Clinical breast examination (CBE)	Perform and assist with a thorough breast exam. Explain the procedure and provide privacy.	Confirmed 2.5‑cm mass in the left breast with slight skin dimpling and palpable left axillary nodes.
Diagnostic mammography	Explain that mammography uses X‑rays to detect abnormalities. Instruct the patient to avoid deodorant before the test. Provide support during the procedure.	Mammogram revealed a suspicious irregular mass with microcalcifications in the upper outer quadrant of the left breast and enlarged axillary nodes.
Breast ultrasound	Describe that ultrasound uses sound waves and is painless. Position the patient and offer reassurance.	Ultrasound confirmed a hypoechoic mass with irregular margins and identified enlarged axillary lymph nodes.
Core needle biopsy	Obtain informed consent, explain that local anaesthesia will be used, and provide emotional support. Monitor for bleeding and infection post‑procedure.	Biopsy specimen showed invasive ductal carcinoma (IDC). Histology grade 2 (moderately differentiated)[7].
Hormone receptor testing	Explain that tissue will be tested for hormone receptors to guide treatment.	Tumour cells tested positive for estrogen receptor (ER+) and progesterone receptor (PR+) and negative for HER2. Hormone‑positive cancers often respond to endocrine therapy[5].
Staging scans (chest CT and bone scan)	Explain purpose (to detect metastasis), ensure intravenous line patency, and monitor for contrast reactions.	No evidence of distant metastasis; disease staged as Stage II (tumour ≤ 5 cm with axillary nodal involvement)[4].
Blood tests (CBC, liver function)	Draw blood, explain possible bruising, and monitor results.	Normal except mild anaemia (Hb 11.2 g/dL), consistent with chronic stress and possible nutritional deficiencies.

Pathophysiology of Breast Cancer

Breast cancer occurs when genetic mutations and hormonal influences cause breast cells to grow uncontrollably, forming a tumour. Invasive ductal carcinoma starts in the milk ducts and invades surrounding tissue[8]. Cancer cells can spread via the lymphatic system or bloodstream to regional lymph nodes and distant organs[9]. Risk factors include age, female gender, obesity, alcohol consumption, family history, and certain reproductive factors[10]. Most breast cancers are hormone receptor positive (HR+), meaning the tumour cells have receptors for estrogen or progesterone[11]. These cancers grow in response to hormones but generally respond well to endocrine therapies, which block hormone effects[5]. HER2-negative status indicates the tumour does not overexpress the HER2 oncogene and therefore will not benefit from HER2‑targeted therapy[12].

Medical Diagnosis

The medical diagnosis is Stage II invasive ductal carcinoma of the left breast, ER-positive, PR-positive, HER2-negative. Stage II means the tumour is ≤ 5 cm and has spread to one to three lymph nodes or is > 5 cm without nodal involvement[4]. Invasive ductal carcinoma describes cancer arising in the milk ducts and invading surrounding tissue[8]. ER-positive and PR-positive indicate the tumour expresses estrogen and progesterone receptors, making it likely to respond to endocrine (hormonal) therapies[5]. HER2-negative means the tumour does not overexpress the HER2 protein, so HER2‑targeted therapies are not indicated[12].

Priority Nursing Problems

Based on the assessment, the following nursing problems are identified:

Anxiety related to a recent cancer diagnosis and uncertainty about prognosis, evidenced by tearfulness, frequent questions, and expressed fear.
Deficient knowledge related to breast cancer, diagnostic procedures, and treatment options, evidenced by misconceptions about causes and treatment, and requests for information.
Disturbed body image related to potential breast surgery and treatment effects, evidenced by expressed concerns about scarring, femininity, and sexual intimacy.
Acute pain related to diagnostic procedures and surgical intervention, evidenced by complaints of discomfort and pain score of 2/10 (anticipated to increase post‑surgery).
Risk for infection related to surgical incision and possible chemotherapy‑induced immunosuppression.
Fatigue related to cancer treatment and emotional stress.
Ineffective coping related to fear of the unknown, family responsibilities, and financial stress.

Nursing Diagnoses for Breast Cancer

Nursing diagnoses translate assessment data into standardised statements that guide care. Five examples for this case are:

Anxiety related to recent cancer diagnosis as evidenced by tearfulness, repeated questions about prognosis, and verbalisation of fear and uncertainty. The unexpected diagnosis and lack of information heighten Mrs. A’s anxiety.
Deficient knowledge related to diagnostic tests and treatment plan as evidenced by misconceptions about breast cancer causes and treatments, and requests for clarification. She needs clear explanations about mammography, biopsy, surgery, and hormonal therapy.
Disturbed body image related to anticipated breast surgery and treatment‑induced changes as evidenced by expressed concerns about scarring, femininity, and sexual intimacy. A fears losing her breast and its impact on her identity.
Acute pain related to tissue biopsy and anticipated surgical incision as evidenced by complaints of mild discomfort, protective movement, and increased heart rate. Pain may increase after lumpectomy and needs management.
Ineffective coping related to financial stress and multiple family responsibilities as evidenced by statements of guilt, difficulty concentrating, and indecision about treatment. A feels overwhelmed by obligations and treatment demands.

Breast Cancer Care Plan

Nursing Diagnosis	Assessment Evidence	Goals/Expected Outcomes	Nursing Interventions	Rationale	Evaluation
Anxiety related to recent cancer diagnosis	Tearfulness, restlessness, repeated questions, expressed fear	Patient will verbalize decreased anxiety within 72 hours, demonstrate effective coping strategies, and participate in treatment decisions.	1. Acknowledge feelings and provide opportunities to ask questions. 2. Explain diagnostic and treatment procedures using simple language. 3. Encourage presence of a support person during discussions. 4. Provide information on support groups and counselling services. 5. Use relaxation techniques such as deep breathing.	Acknowledging feelings validates the patient’s experience and builds trust.

Assess pain location, intensity, and characteristics regularly using a numeric scale. 2. Administer prescribed analgesics before pain becomes severe. 3. Teach and encourage use of non‑pharmacologic methods (relaxation, positioning, cold/heat as appropriate). 4. Monitor for analgesic side effects. 5. Collaborate with the surgical team to adjust medications if pain is uncontrolled.	Regular assessment facilitates early intervention. Pre‑emptive analgesia prevents escalation. Non‑pharmacologic methods complement medications. Monitoring side effects ensures safety. Collaboration ensures adequate pain management.	Patient reports manageable pain and demonstrates use of relaxation techniques.
Ineffective coping related to stress and family responsibilities	Expresses guilt, difficulty making decisions, financial concerns	Patient will identify coping strategies and supportive resources and demonstrate improved mood within one week.	1. Assess coping style and previous strategies. 2. Encourage expression of fears and concerns. 3. Provide information on financial assistance and social services. 4. Suggest journaling or mindfulness to process emotions. 5. Refer to a social worker and psychological counsellor.	Assessing current coping allows tailored interventions. Verbalizing concerns reduces emotional burden. Financial information alleviates stress. Mindfulness and journaling promote self‑reflection. Professional support provides structured coping strategies.	Patient identifies support resources, reports reduced stress, and demonstrates positive coping behaviours.

Treatment Plan and Nursing Management

For Stage II ER/PR‑positive, HER2‑negative IDC, treatment often includes surgery, possible radiation, chemotherapy based on nodal involvement, and hormone therapy[13]. The nurse plays a critical role at each stage.

Surgical management – Mrs. A is scheduled for a breast‑conserving surgery (lumpectomy) with sentinel lymph node biopsy. The nurse will:
Explain the procedure, expected duration, and potential risks. Discuss the difference between lumpectomy and mastectomy and emphasise that sentinel node biopsy removes only a few lymph nodes[14] to reduce lymphedema risk.

Verify informed consent and ensure the surgical site is correctly marked.
Provide preoperative instructions on fasting, medications, and skin preparation.
Offer emotional support and answer questions using simple language.
Monitor vital signs, IV access, and sedation levels during the peri‑operative period.
Post‑operatively, assess the surgical site for bleeding or hematoma, manage pain, and educate about wound care and activity restrictions. Teach arm exercises to prevent stiffness and lymphedema.

Reinforce the importance of drain management if a drain is placed, instructing on emptying, measuring output, and infection signs.
Radiation therapy – After lumpectomy, adjuvant radiation reduces recurrence[15]. The nurse should:
Explain the purpose and schedule of radiation therapy. Describe that treatments are painless and given daily for several weeks.

Assess the skin for erythema, dryness, or desquamation, and teach gentle skin care (avoid perfumes, use mild soap, and protect from sun exposure).
Monitor fatigue, a common side effect; encourage rest and balanced activity.

Provide emotional support and coordinate transportation if needed.
Chemotherapy – If pathology shows extensive lymph node involvement, adjuvant chemotherapy may be recommended. The nurse should:
Explain chemotherapy regimen, administration method (often intravenous), and expected duration.

Assess for nausea, vomiting, mucositis, alopecia, and myelosuppression. Provide antiemetics, mouth care guidance, and strategies for hair loss (head coverings, wigs).
Monitor laboratory values (complete blood count) and report neutropenia or anaemia. Educate about infection prevention (hand hygiene, avoiding crowds) and when to seek medical attention (fever, persistent sore throat).

Encourage adequate hydration and nutrition to combat fatigue and support recovery.
Hormone therapy – For ER/PR‑positive cancers, endocrine therapy such as tamoxifen or aromatase inhibitors is prescribed to reduce recurrence[5]. The nurse should:
Educate about medication adherence (daily oral pills for 5–10 years) and potential side effects (hot flashes, joint pain).

Encourage regular bone density assessments, as aromatase inhibitors can decrease bone density.

Advise on lifestyle modifications (weight‑bearing exercise, adequate calcium and vitamin D).
Follow‑up and survivorship care – Regular follow‑up ensures early detection of recurrence and management of long‑term effects. The nurse will:
Schedule appointments for clinical exams and mammography as recommended.

Monitor for late side effects such as lymphedema, bone health changes, or cognitive issues.
Provide survivorship care plans summarising treatment history, surveillance, and health promotion.

Nursing Interventions for Breast Cancer

Assess pain and anxiety regularly. Pain and anxiety can fluctuate; frequent assessment using validated scales ensures timely intervention.
Provide clear explanations before procedures. Explain what the patient will feel during mammography, biopsy, or radiation to reduce fear and promote cooperation.
Encourage questions and teach‑back. Ask the patient to repeat information in her own words; this verifies understanding and corrects misconceptions.
Monitor the surgical wound and drains. Inspect for redness, swelling, drainage, or dehiscence. Measure drain output and teach the patient to record it.
Teach signs of infection. Instruct the patient to report fever, redness, warmth, purulent discharge, or increasing pain promptly. Early intervention prevents complications.
Support nutrition and hydration. Encourage balanced meals with adequate protein, fruits, vegetables, and hydration to aid healing and counteract treatment side effects. Suggest small frequent meals if appetite is reduced.
Encourage rest and light activity. Fatigue is common after surgery and during therapy. Recommend short naps, gentle exercises, and gradual return to normal activities.
Provide emotional support. Use therapeutic communication, active listening, and empathy. Acknowledge fears and normalise emotional reactions.
Discuss body image concerns sensitively. Provide information about reconstructive options, prostheses, and support groups. Encourage the patient to express feelings about femininity and sexuality.
Teach lymphedema prevention. Instruct on arm exercises, avoiding heavy lifting, using compression garments if recommended, and protecting the affected arm from injury.
Encourage adherence to appointments and medications. Provide a calendar or digital reminders. Stress the importance of completing radiation and hormone therapy to reduce recurrence risk[16].

Patient Education

Education empowers patients to participate actively in their care and enhances outcomes. Key teaching points for Mrs. A include:

Understanding the diagnosis: Explain that IDC arises in milk ducts and has spread locally but not to distant organs. Clarify Stage II criteria[4] and hormone receptor status. Emphasize that early detection improves survival[2].
Treatment options: Describe lumpectomy versus mastectomy, sentinel lymph node biopsy, radiation, chemotherapy, and hormone therapy. Discuss the goal of each treatment (removal of tumour, preventing recurrence, killing any remaining cancer cells).
What to expect before and after surgery: Instruct on fasting, medication adjustments, and showering with antiseptic soap preoperatively. Explain post‑operative care: incision care, pain management, drain care, and activity restrictions (avoid lifting more than 5 kg with the affected arm until cleared).
Wound care: Teach how to inspect the incision, keep it clean and dry, and when to change dressings. Emphasize hand hygiene before touching the site.
Medication adherence: Stress the importance of taking hormone therapy as prescribed, not skipping doses, and reporting side effects.
Signs of infection: Fever > 38 °C, increasing redness, swelling, or discharge. Advise seeking medical help promptly.
Side effects of therapy: Discuss common chemotherapy and radiation side effects (fatigue, nausea, hair loss, skin changes) and coping strategies (antiemetics, small meals, rest). Explain that endocrine therapy may cause hot flashes, mood changes, or joint pain.
Nutrition: Encourage a balanced diet rich in fruits, vegetables, lean proteins, whole grains, and hydration. Limit alcohol and avoid smoking. Consider referral to a dietitian for personalised advice.
Fatigue management: Advise scheduling rest periods, prioritising activities, and engaging in light exercises such as walking to maintain energy.
Emotional coping: Encourage sharing feelings with trusted friends or counsellors. Provide information on support groups and psychological services.
Breast awareness: Teach self‑exam for the contralateral breast and emphasise the importance of routine mammograms and clinical exams.
Follow‑up appointments: Emphasise adherence to follow‑up visits for physical exams, mammography, and assessment of therapy side effects.
When to seek urgent care: Difficulty breathing, persistent chest pain, uncontrolled bleeding, severe pain unrelieved by medication, or signs of deep vein thrombosis (calf swelling/pain).

Psychosocial and Emotional Support

Breast cancer affects patients beyond the physical dimension. Mrs. A fears death, disfigurement, and treatment side effects. She worries about intimacy with her husband and the impact on her role as a mother and caregiver. Financial stress and cultural beliefs about natural healing add complexity. The nurse should use therapeutic communication—listening without judgment, providing privacy, and offering empathic responses. Encourage expression of emotions and normalise fears. Provide information on counselling, support groups, and survivorship programs. Explore cultural and spiritual beliefs and integrate them into care when possible. Recognise the potential impact on sexuality and discuss strategies to maintain intimacy (open communication with partner, using lubricants for vaginal dryness, planning intimate moments when not fatigued). Encourage involvement of the family in education sessions so they can provide better support.

Discharge Planning and Follow‑Up

Discharge planning begins at admission and ensures continuity of care. Key components for Mrs. A include:

Wound care instructions: Keep incision dry for 48 hours, change dressings as directed, and watch for infection signs.
Pain management: Take prescribed analgesics on schedule; monitor for constipation or nausea. Use relaxation techniques and arm positioning to reduce discomfort.
Activity restrictions: Avoid heavy lifting, vigorous exercise, or driving until cleared. Perform gentle arm exercises to maintain range of motion.
Lymphedema prevention: Elevate the arm on the affected side, avoid blood pressure measurements, injections, or blood draws in that arm, and wear loose clothing.
Drain care: If a drain is present, measure and record output, empty when 30–50 mL is collected or twice daily, and maintain sterility.
Follow‑up appointments: Provide a schedule for surgical review, pathology results discussion, and oncology consultations. Emphasise that completing the full course of treatment improves outcomes[16].
Referrals: Arrange appointments with an oncology nurse specialist, dietitian, physical therapist (for arm exercises), social worker (for financial assistance), and psychologist or counsellor.
Survivorship plan: Provide a written plan summarising diagnosis, treatments received, potential late effects, recommended follow‑up tests, and health promotion strategies.

Evaluation of Nursing Care

Evaluation determines whether nursing interventions achieve desired outcomes. Indicators of effective care for Mrs. A include:

Patient verbalises understanding of her diagnosis, treatment plan, and self‑care measures, as verified through teach‑back.
Anxiety decreases, evidenced by calmer demeanour, fewer repetitive questions, and ability to participate in decisions.
Pain is controlled at ≤ 3/10, and non‑pharmacologic techniques are used.
Surgical wound is clean, with no signs of infection. Drain output decreases and is within expected ranges.
Patient attends follow‑up appointments and adheres to radiation and hormone therapy schedules.
Patient demonstrates correct wound care, arm exercises, and drain management.
Patient expresses improved coping, uses identified support resources, and reports feeling supported by her family and health‑care team.

Reflection

This case study highlights the multifaceted role of nursing in breast cancer care. From a nursing perspective, early assessment and recognition of breast lumps are crucial; in this case, patient education could have prompted earlier presentation. Holistic care addresses not only physical needs but also emotional, social, and spiritual concerns. Therapeutic communication builds trust and reduces anxiety. Patient education empowers individuals to participate in their care and improves adherence to treatment. Evidence‑based practice ensures that interventions are grounded in current research, such as using sentinel node biopsy to reduce complications[14] and prescribing endocrine therapy for hormone‑positive tumours[5]. Advocacy for patients’ rights, including access to information and support services, is central. Respecting patient dignity and cultural beliefs strengthens care relationships. As a nursing student, I learned that collaborative teamwork, empathy, and clear communication are as important as clinical skills in oncology nursing.

Breast Cancer Case Study Questions and Answers

What is the priority nursing assessment when a patient presents with a new breast lump?
The nurse should obtain a detailed history (onset, changes, associated symptoms) and perform a focused breast examination, assessing the size, location, consistency, and mobility of the lump, as well as checking regional lymph nodes. Vital signs and psychosocial state should be assessed to identify anxiety or distress.
Name three risk factors for breast cancer present in this case.
Risk factors include age over 45, family history of breast and ovarian cancer, overweight status, late age at first full‑term pregnancy, limited physical activity, and alcohol consumption[6].
What diagnostic tests confirmed the diagnosis of invasive ductal carcinoma?
Diagnostic mammography and breast ultrasound identified a suspicious mass. A core needle biopsy provided tissue for histology, confirming invasive ductal carcinoma. Hormone receptor testing showed ER and PR positivity and HER2 negativity.
What is the significance of ER‑positive and PR‑positive status?
Tumours that are ER‑positive and PR‑positive have receptors for estrogen and progesterone. These cancers generally grow in response to hormones but respond well to endocrine therapy (e.g., tamoxifen or aromatase inhibitors) that blocks hormonal stimulation[5].
Which nursing diagnosis is priority immediately after surgery and why?
Acute pain related to surgical incision is a priority because uncontrolled pain can impede respiratory effort, mobility, and wound healing. Effective pain management promotes recovery and enables the patient to participate in deep‑breathing exercises and early ambulation.
List four nursing interventions after lumpectomy with sentinel lymph node biopsy.

Monitor vital signs and surgical site for bleeding or hematoma.
Assess and manage pain using prescribed analgesics and positioning.
Teach wound care and drain management.

Initiate gentle arm exercises to prevent stiffness and lymphedema while avoiding heavy lifting.[14]
What patient education is essential regarding hormone therapy?
Explain the purpose (reducing recurrence), duration (often 5–10 years), and importance of adherence. Discuss potential side effects, such as hot flashes and joint pain, and strategies to manage them (e.g., light clothing, exercise). Emphasise not to stop medication without consulting the oncology team[5].
How can nurses support the psychosocial needs of breast cancer patients?
By providing a safe environment for patients to express feelings, using active listening and empathy, addressing body image and sexuality concerns, involving family in care discussions, and referring patients to support groups, counsellors, or spiritual care providers.
What signs of complications should patients watch for after breast cancer surgery?
Signs of infection (fever, redness, swelling, purulent discharge), hematoma (increasing swelling or pain), lymphedema (arm swelling), and impaired mobility or numbness. Patients should also report persistent nausea, vomiting, or bleeding.
What elements should be included in discharge planning for breast cancer patients?
Discharge planning should include wound and drain care instructions, pain management, activity restrictions, lymphedema prevention strategies, a schedule for follow‑up appointments, referrals to allied health professionals, education on medication adherence, and psychosocial support resources.
