Breast cancer is the type of cancer which starts in the breasts, most often in the lobules or ducts. The lobules are the glands that make milk and the ducts carry the milk from the lobules to the nipples. The cancer forms when cells grow abnormally and, in most cases, form a mass called a tumor. For women, breast cancer is one of the most common types of cancer in the United States. Although rare, breast cancer can occur in men as well.
Are there multiple types of breast cancer?
Yes, there are several types of breast cancer. Common types of cancer include ductal carcinoma, invasive lobular carcinoma, Paget disease, inflammatory breast cancer, and triple negative breast cancer. Each type has different symptoms and affect different areas of the breast tissue.
What causes breast cancer?
At this time, doctors do not know the exact reason that the cells divide abnormally and form breast cancer. However, research has shown that there are risk factors that may elevate your risk of having breast cancer.
Can breast cancer spread to other areas of the body?
Yes, breast cancer can grow into nearby tissues in the breast or in the lymphatic systems. If this occurs, cancer cells may be found in the lymph nodes found under the arm pit. Additionally, breast cancer can spread to other organs of the body. When this happens, it is called metastatic brain cancer.
