IDC develops in the breast tissue of the milk ducts but spreads past the walls of the ducts into the surrounding fatty tissue of the breast. IDC is able to metastasize to the lymph nodes through the lymphatic system or other parts of the body through the blood stream. The second most common type of breast cancer is invasive lobular carcinoma (ILC). Approximately 1in 10 invasive breast cancers are diagnosed as ILC, however it is usually more difficult to detect by a mammogram that IDC. ILC differs from IDC in that ILC begins to develop in the cells that line the lobules, milk producing glands, of the breast. This type of cancer has spread past the walls of the lobules and attacked surrounding breast tissue. Similarly, ILC can metastasize outside of the breast to other areas of the
