Breast Cancer

Breast cancer is a malignant proliferation of epithelial cells lining the ducts or lobules of the breast. It represents a heterogeneous group of tumors with varying molecular profiles, clinical behaviors, and responses to therapy.

Etiology involves the interplay of genetic predisposition (BRCA1/2 mutations), endocrine factors (prolonged estrogen exposure), and environmental/lifestyle influences.

Pathogenesis involves the accumulation of somatic mutations in oncogenes and tumor suppressor genes. This leads to unregulated cellular proliferation, evasion of apoptosis, and potential for metastatic spread via the lymphatic and hematogenous systems.

It is the most frequently diagnosed cancer in women globally. Prevalence increases with age; while rare in males (1% of cases), it is the most common female malignancy, with lifetime risks approximately 1 in
8.

Age, female gender, early menarche, late menopause, nulliparity, postmenopausal obesity, alcohol consumption, radiation exposure, and family history.

A. Early Symptoms: Palpable, painless breast mass; focal area of firmness.
B. Common Symptoms: Nipple discharge, retraction, skin dimpling, breast asymmetry.
C. Advanced Symptoms: Bone pain, dyspnea, jaundice, weight loss.
D. Emergency Symptoms: Hypercalcemia (confusion, polyuria), spinal cord compression, respiratory distress.

Inspection: Skin changes (peau d’orange), nipple inversion. Palpation: Firm, irregular, fixed mass; axillary lymphadenopathy.

A. Clinical Assessment: Breast exam, history.
B. Laboratory Testing: CBC, liver function, serum calcium.
C. Imaging Studies: Mammography, Ultrasound, MRI.
D. Functional Tests: PET-CT for staging.
E. Biopsy Findings: Core needle biopsy for histopathology and immunohistochemistry (ER, PR, HER2).
F. Genetic Testing: BRCA1/2, PALB2, Oncotype DX.
G. Differential Diagnosis: Fibroadenoma, fibrocystic changes, mastitis.

Test Name: CA 15-3
Type: Blood Test
Purpose: Tumor marker tracking
Expected Findings: Elevated in metastatic disease
Interpretation: Indicates disease progression or treatment response.

Mammography: Baseline and diagnostic, identifies microcalcifications.
Breast MRI: Superior sensitivity for high-risk screening and surgical planning.
PET-CT: Used for distant staging of advanced disease.

Benign breast disease (fibroadenoma), breast abscess, fat necrosis, and Paget’s disease of the nipple.

Lymphedema, treatment-induced cardiac toxicity, secondary malignancies, osteoporosis, metastasis to bone/liver/lung.

A. Lifestyle Modifications: Weight management, moderate exercise.
B. Preventive Measures: Prophylactic mastectomy or tamoxifen in high-risk patients.
C. Medical Treatment: Chemotherapy (Anthracyclines), Endocrine therapy (Tamoxifen, Aromatase Inhibitors), Targeted therapy (Trastuzumab).
D. Surgical Treatment: Lumpectomy (BCS), Mastectomy, Sentinel lymph node biopsy.
E. Interventional Procedures: Radiation therapy.
F. Rehabilitation: Physical therapy for lymphedema.
G. Emergency Management: Bisphosphonates for hypercalcemia.

5-year survival rate exceeds 90% for localized disease; significantly lower for stage IV metastatic disease.

Regular mammographic screening, genetic counseling for high-risk families, and limiting hormone replacement therapy.
