About Breast Cancer

Types of Breast Cancer

Breast cancer occurs when breast cells divide and grow without control, sometimes invading surrounding tissue. In some cases, the cancer may grow very slowly while in others, it develops more rapidly. Most breast cancers start in the ducts while a small number start in the milk sacs or lobes.


Breast cancer can be classified generally as follows
Non-Invasive Breast Cancer

Cancer that is confined to the ducts (Ductal Carcinoma In Situ or DCIS) or lobules (Lobular Carcinoma In Situ or LCIS). DCIS is considered a precancerous condition while LCIS is a risk factor for invasive cancer.

Invasive Cancer
Cancer that has spread beyond the ducts or lobes to the surrounding breast tissue. Generally most treatable in the early stage when the tumor is relatively small and has not spread to the lymph nodes.

Metastatic Breast Cancer

Cancer that has spread outside the breast to other parts of the body. If cancer cells are detected in the lymph nodes under the arm, it may mean that it has spread to other lymph nodes and organs such as the bones, liver or lungs.
