Q. What is breast cancer?
Breast cancer is a malignant (cancerous) disease that starts from cells of the breast. These cancerous cells can spread to other parts of the body via the bloodstream or lymphatic system and continue the uncontrolled growth with fatal results. At first, the cancer grows very slowly. For two to three years it may be detectable by mammography before it can be detected by hand. Cancer detected and treated early is usually curable.
