5 Signs Of Breast Cancer

According to the CDC, breast cancer is among the most prevalent cancers found among American women. Each year, the United States sees 250,000 new cases of breast cancer in women alone. While breast cancer deaths have seen a decline over time, these cancers are still the second most common cause of United States women's cancer deaths overall.

Types Of Breast Cancer

There are two common types of breast cancer: invasive ductal carcinoma and invasive lobular carcinoma. In the first, cancer cells are found to grow outside breast ducts and into other segments of breast tissue. When the cancer cells are invasive, they can also metastasize, or spread, beyond the breasts to other body parts.

In the second, cancer cells are found to spread from lobules to nearby breast tissues. Again, these invasive cells can spread outward into the body. Other types of breast cancer include Paget's disease, mucinous, inflammatory, and medullary breast cancer. DCIS, or ductal carcinoma in situ, is a disease of the breasts that can result in breast cancer. The cancer cells in this condition are only found in the ducts' lining, not having spread beyond to other breast tissues.
