Breast Cancer

Breast Cancer is a condition in which the regulation of cell growth is lost, and cells grow uncontrollably within the breast, creating tumors. Cancer cells differ from regular, healthy cells in that they are no longer well-regulated, and continue to reproduce irregular cells after the point which the cells should have died. Breast cancer commonly begins in the cells of milk-producing glands or ducts called lobules, but sometimes takes root in the stromal tissues, including the fatty and fibrous connective tissues. These abnormal cells may spread through the breast to the underarm lymph nodes before spreading to other parts of the body. Stages of breast cancer correlate with how far the cancer cells have spread from the primary tumor. Breast cancer is always caused by genetic anomaly, however only 5-10% of cancers are inherited. More commonly, breast cancer is caused by genetic anomalies due to aging and normal bodily wear and tear.
