What are possible Treatments?

radiation therapy: ionizing radiation damages DNA to destroy the cell or slows the development of abnormal cells.
1. Basal Cell Carcinoma
2. Squamous cell carcinoma
Originates from epithelial cells
3. Malignant Melanoma
Difficult to treat due to fast growing and invasion of deep tissues
Risk increases with short, intermittent exposure to high-intensity sunlight.
about 5-10% of breast cancers can be linked to gene mutations (abnormal changes) inherited from one’s mother or father. Mutations of the BRCA1 and BRCA2 genes are the most common. Women with these mutations have up to an 80% risk of developing breast cancer during their lifetime, and they are more likely to be diagnosed at a younger age (before menopause). An increased ovarian cancer risk is also associated with these genetic mutations. In men, about 1 in 10 breast cancers are believed to be due to BRCA2 mutations and even fewer cases to BRCA1 mutations.
About 70-80% of breast cancers occur in women who have no family history of breast cancer. These occur due to genetic abnormalities that happen as a result of the aging process and life in general, rather than inherited mutations.
