BREAST CANCER
Simply put, breast cancer is an uncontrolled growth of breast cells. To better understand breast cancer, it would help to understand how any cancer develops. Cancer occurs as a result of transformations, or abnormal changes, in the genes that regulates the growth of cells and keeps them healthy. The genes are found in each cell's nucleus, and acts as the control room of each cell. The cells in our bodies normally, replace themselves through an orderly process of cell growth (healthy new cells take over as old ones die out). However over time, the transformation can turn on certain genes and turn off others in a cell. Due to the turn off, the changed cell gains the ability to keep dividing without control or order, producing more cells like itself and form a tumor. A tumor can be benign (i.e. not dangerous to health) or will maintain the potential to be dangerous (malignant). Benign tumors are not considered cancerous (i.e. their cells are close to normal in appeara...
