A review on breast cancer

Cancer is a malignant growth resulting from uncontrolled division of abnormal cells. Breast cancer is the second leading cause of cancer death among women. The cause of breast cancer is not known although multiple factors like genetics, life style and hormonal imbalances predispose breast cancer. It usually presents with lump in either side of the breast with or without other symptoms like breast changes, pain and nipple discharge. Radiological examination is the mainstay for breast cancer screening and detection. Early diagnosis ameliorates survival rate. Treatment modalities available for breast cancer are surgery, chemotherapy, radiotherapy, immunotherapy, targeted therapy and complementary alternative medicine. The main objectives of treatment are to reduce local tumor recurrence, risk of metastasis and to improve patient quality of life with minimal adverse effects. Diet and life style plays a key role in prognosis and quality of life of cancer treated patients.
