Study Notes
Diagnosis
- Breast cancer diagnosis involves a combination of:
- Clinical breast examination (CBE)
- Mammography
- Ultrasound
- Magnetic Resonance Imaging (MRI)
- Biopsy (core needle or surgical)
- Diagnostic tests may include:
- Fine Needle Aspiration (FNA)
- Ductal Lavage
- Genetic testing (e.g., BRCA1, BRCA2)
Symptoms
- Early symptoms may not be present or noticeable
- Common symptoms:
- Lump or thickening in the breast or underarm
- Changes in breast size or shape
- Skin changes (redness, swelling, or dimpling)
- Nipple discharge or changes
- Breast pain or tenderness
- Less common symptoms:
- Swelling of the arm or hand
- Nipple retraction or inversion
- Breast skin changes (ulceration, ridging, or crusting)
Treatment Options
- Surgery:
- Lumpectomy (removes tumor and surrounding tissue)
- Mastectomy (removes entire breast)
- Sentinel node biopsy (removes lymph nodes)
- Radiation therapy:
- External beam radiation
- Internal radiation (brachytherapy)
- Chemotherapy:
- Systemic therapy (targets entire body)
- Targeted therapy (targets specific cancer cells)
- Hormone therapy:
- Aims to reduce estrogen levels or block estrogen receptors
- May be used alone or in combination with other treatments
- Targeted therapy:
- Trastuzumab (Herceptin) targets HER2 protein
- Other targeted therapies (e.g., lapatinib, pertuzumab)
Stages
- Breast cancer stages are classified using the TNM system:
- T (tumor size and extent)
- N (lymph node involvement)
- M (distant metastasis)
- Stages:
- Stage 0 (carcinoma in situ, non-invasive)
- Stage I (early, invasive, small tumor)
- Stage II (early, invasive, larger tumor)
- Stage III (locally advanced, invasive)
- Stage IV (metastatic, cancer has spread)
Risk Factors
- Non-modifiable risk factors:
- Female gender
- Age (increases with age)
- Family history (first-degree relatives)
- Genetic mutations (BRCA1, BRCA2)
- Personal history of breast cancer or benign breast disease
- Modifiable risk factors:
- Hormone replacement therapy (HRT)
- Oral contraceptive use
- Physical inactivity
- Obesity
- Diet high in fat and calories
- Alcohol consumption
Diagnosis
- Combination of clinical breast examination, mammography, ultrasound, MRI, and biopsy is used for diagnosis
