About Breast Cancer

Breast cancer is the most common cancer among women. It is also the second most common cancer overall. An estimated 232,030 cases of invasive breast cancer were diagnosed in the U.S. in 2014. Breast cancer can be treated, and understanding breast cancer is important for everyone.

Non-invasive Breast Cancer

Non-invasive breast cancer stays within the milk ducts or lobules in the breast. It does not grow into or invade normal tissues within or beyond the breast. Non-invasive cancers are sometimes called pre-cancers.

Invasive Breast Cancer

Invasive breast cancer grows into normal, healthy tissues. Most breast cancers are invasive. Cancer cells can travel from the breast to other parts of the body through the blood stream or the lymphatic system.

In some cases, breast cancer may be both invasive and non-invasive. This means that part of the cancer has grown into normal tissue and part of the cancer has stayed inside the milk ducts or milk lobules.
