Breast Cancer Staging
Cancer staging refers to a classification that is used to describe the extent to which a cancer has spread.

If breast cancer is detected, a number of tests will be needed to determine the tumor's size, location, and possible spread to other parts of the body. The staging evaluation may include a chest x-ray, CT scanning of the chest or abdomen, ultrasound and bone scan.

Breast cancer stages:

• Stage 0 breast cancer, or Carcinoma in Situ
• Ductal carcinoma in situ
• Lobular carcinoma in situ
• Stage 1 breast cancer
• Stage 2A breast cancer
• Stage 2B breast cancer
• Stage 3A breast cancer
• Stage 3B breast cancer
