Breast cancer types

There are several different types of breast cancer. To determine the best approach to treating the disease, your doctor will first evaluate the specifics of the breast tumor, including:

  1. If the disease has spread beyond the breast
  2. The type of tissue where the disease began

Types of Breast Cancer

Types of breast cancer

Breast cancer occurs in two broad categories: noninvasive and invasive.

  • Noninvasive (in situ) breast cancer: Cancerous cells remain in a particular location of the breast, without spreading to surrounding tissue, lobules or ducts.
  • Invasive (infiltrating) breast cancer: Cancerous cells break through normal breast tissue barriers and spread to other parts of the body through the bloodstream and lymph nodes.

Breast cancer is also classified based on where in the breast the disease started (e.g., milk ducts, lobules), how the disease grows, and other factors. The tabs on the left provide an overview of some common types of breast cancer.

Some other types of breast cancer include, but are not limited to: Paget's disease of the nipple, sarcoma of the breast, medullary carcinoma, tubular carcinoma, mucinous carcinoma, metaplastic carcinoma, adenocystic carcinoma, phyllodes tumor and angiosarcoma.
