The following types of breast cancer are found in men:
- Infiltrating ductal carcinoma: Cancer that has spread beyond the cells lining ducts in the breast. Most men with breast cancer have this type of cancer.
- Ductal carcinoma in situ: Abnormal cells that are found in the lining of a duct; also called intraductal carcinoma.
- Inflammatory breast cancer: A type of cancer in which the breast looks red and swollen and feels warm.
- Paget disease of the nipple: A tumor that has grown from ducts beneath the nipple onto the surface of the nipple.
Locally advanced breast cancer
When the cancer has spread to one or more of, the lymph nodes or other areas near the breast, or to tissues around the breast such as the skin, muscles or ribs, but there is no sign that it has spread to other parts of the body.
Secondary or Metastatic breast cancer
The terms metastatic, secondary and advanced are often used interchangeably. Secondary breast cancer is the term used to describe cancer that has spread from the original site in the breast to other organs or tissues in the body. The cancer may have spread to lymph nodes (not near the breast), the brain, liver, lungs or bones.
