Study Notes
What is Breast Cancer?
- A type of cancer that originates in the breast tissue
- Can affect both women and men, but more common in women
- Accounts for about 15% of all cancer cases in women worldwide
Types of Breast Cancer
- Ductal carcinoma in situ (DCIS): Cancer cells in the lining of the milk ducts, has not invaded surrounding tissue
- Invasive ductal carcinoma (IDC): Cancer cells invade surrounding tissue
- Lobular carcinoma in situ (LCIS): Cancer cells in the lobules, has not invaded surrounding tissue
- Invasive lobular carcinoma (ILC): Cancer cells invade surrounding tissue
Causes and Risk Factors
- Genetics: Family history, inherited genetic mutations (e.g. BRCA1, BRCA2)
- Hormonal factors: Early menstruation, late menopause, hormone replacement therapy
- Lifestyle factors: Obesity, physical inactivity, alcohol consumption
- Environmental factors: Radiation exposure, certain chemicals
Symptoms
- Lump or thickening in the breast or underarm
- Changes in breast size, shape, or color
- Nipple discharge or inversion
- Redness, scaliness, or swelling of the breast
Diagnosis
- Clinical breast examination (CBE)
- Mammography: X-ray of the breast tissue
- Ultrasound: Uses high-frequency sound waves to produce images
- Biopsy: Removal of tissue or cells for examination
Treatment
- Surgery: Lumpectomy (removal of tumor), mastectomy (removal of breast)
- Radiation therapy: Uses high-energy radiation to kill cancer cells
- Chemotherapy: Uses drugs to kill cancer cells
- Hormone therapy: Targets hormone-sensitive cancers
- Targeted therapy: Targets specific cancer cells
