What are the causes and symptoms of Brease Cancer
The exact causes of breast cancer are largely unknown, but both environmental and genetic factors are involved. A family history of breast cancer increases risk. Specific mutations in genes called HER2, BRCA1, BRCA2, and p53 have been linked to breast cancer; these mutations may be inherited or acquired. Prolonged exposure to the hormone estrogen, as when menstruation starts before age 12 and continues beyond age 50, favours development of cancer, and women who have had certain kinds of benign tumours are also more prone to developing breast cancer. Other risk factors may include lack of exercise, use of oral contraceptives, alcohol consumption, and previous medical treatments involving chest irradiation.
The most common symptom of breast cancer is an abnormal lump or swelling in the breast, but lumps may also appear beside the breast or under the arm. Other symptoms may include unexplained breast pain, abnormal nipple discharge, changes in breast texture, or changes in the skin on or around the breast.
