Myth: most breast cancer is genetic.
fact: only 5% to 10% of breast cancers are caused by mutations in BRCA1 and BRCA2. According to the American Cancer Society (ACS), even women with a family history of breast cancer do not have clear genetic mutations in many cases, but are associated with a common lifestyle and genetic predisposition.
in fact, scientists still do not find the true cause of breast cancer. The best way to do this is to compare women who have never had breast cancer with those who are diagnosed or who are at high risk.
error two: small chest of women with low probability of illness.
fact: whether breast cancer has little to do with bra size. The development of all breast cancer cells are associated with breast ductal or lobular, both of which is the number of all women are the same, its main function is to make milk and transported to the nipple. The size of the breast, usually with the amount of fat matrix (fiber tissue), which has little to do with the risk of breast cancer. Recommendation: all women over the age of 40 should undergo regular breast X light screening.
error three: there will be a lump.
fact: about 10% of breast cancer patients are diagnosed with no lumps, pain, or other symptoms. In the detected mass, 80% to 85% are benign, they often cysts or non cancerous tumors, called fibroadenomas. In other words, the doctor should have all the breast lumps or other symptoms of the breast (especially the listed below).
