One in every eight women will develop breast cancer at some point in their lives. The chances of developing breast cancer increase with age. At age 50, the chances of developing breast cancer are 1 in 50. And, by age 85, the chances have increased to 1 in 8. There are two common kinds of breast cancer, ductal and lobular.
Tumors can develop in one or both breasts.
In ductal cancer, the malignant cells grow along the ducts or thin tubes connecting the lobes of the breast to the nipple. Invasive ductal cancer is the most common of all breast cancers. In lobular cancer, the cancer cells develop within the lobules of the milk-secreting glands at the end of the ducts. Lobular cancer is more likely to appear in both breasts.
