Cancer, breast
Also known as: Breast cancer
Breast cancer is cancer that forms in the cells of the breasts. It is the most common cancer diagnosed in women in the United States after skin cancer. Breast cancer can also occur in men but is far more common in women. Advances in screening, diagnosis, and treatment have led to improved survival rates and a decrease in deaths from breast cancer.
SYMPTOMS
- A breast lump or thickening
- Bloody discharge from the nipple
- Changes in breast size, shape, or appearance
- Changes to the skin over the breast
- Inverted nipple
- Peeling, scaling, or flaking of the skin around the nipple
- Redness or pitting of the skin over the breast
When to see a doctor: If you notice any changes in your breasts, even if recent screenings were normal, it's important to see your doctor promptly for evaluation.
CAUSES
The exact cause of breast cancer is not known. It occurs when breast cells grow abnormally and form a mass or lump. Hormonal, lifestyle, and environmental factors may increase the risk of breast cancer. About 5-10% of breast cancers are linked to inherited gene mutations like BRCA1 and BRCA2.
RISK FACTORS
Risk factors for breast cancer include being female, increasing age, personal or family history of breast cancer, inherited gene mutations, radiation exposure, obesity, early menstruation or late menopause, and hormone therapy among others.
Tests and Diagnosis
Tests used for diagnosing breast cancer include breast exams, mammograms, ultrasounds, biopsies, and MRIs. Staging helps determine the extent of cancer spread using blood tests and imaging studies.
TREATMENTs and Drugs
Treatment options include surgery (lumpectomy or mastectomy), radiation therapy, chemotherapy, hormone therapy, targeted drugs like trastuzumab and lapatinib. Lifestyle changes such as exercise, limiting alcohol intake, maintaining a healthy weight can also reduce risk.
