Types of breast cancer

There are several different types of breast cancer.

Find out more about the different types of breast cancer by clicking on the links below:

  • Ductal carcinoma in situ (DCIS) is a non-invasive breast cancer that is confined to the ducts of the breast.
  • Lobular carcinoma in situ (LCIS) is a non-invasive breast cancer that is confined to the lobules of the breast.
  • Early breast cancer is an invasive breast cancer that is contained in the breast and may or may not have spread to lymph nodes in the breast or armpit. Some cancer cells may have spread outside the breast and armpit area but cannot be detected. 
  • Paget’s disease of the nipple is a rare form of breast cancer that affects the nipple and the area around the nipple (the areola), and is commonly associated with an invasive cancer elsewhere in the breast.
  • Inflammatory breast cancer is a rare form of invasive breast cancer that affects the lymphatic vessels in the skin of the breast, causing the breast to become red and inflamed. 
  • Locally advanced breast cancer is an invasive breast cancer that has spread to areas near the breast, such as the chest wall. 
  • Secondary breast cancer (also called metastatic or advanced breast cancer) is an invasive breast cancer that has spread from the breast to other parts of the body.
