What Are the Stages of Breast Cancer?
Early stage or stage 0 breast cancer is when the disease is localized to the breast with no evidence of spread to the lymph nodes (carcinoma in situ).
Stage I breast cancer: The cancer is 2 centimeters or less in size and it hasn't spread anywhere.
Stage IIA breast cancer is a tumor smaller than 2 centimeters across with lymph node involvement or a tumor that is larger than 2 but less than 5 centimeters across without underarm lymph node involvement.
Stage IIB is a tumor that is greater than 5 centimeters across without underarm lymph nodes testing positive for cancer or a tumor that is larger than 2 but less than 5 centimeters across with lymph node involvement.
Stage IIIA breast cancer is also called locally advanced breast cancer. The tumor is larger than 5 centimeters and has spread to the lymph nodes under the arm or near the breastbone, or a tumor that is any size with cancerous lymph nodes that adhere to one another or surrounding tissue.
Stage IIIB breast cancer is a tumor of any size that has spread to the skin or chest wall.
Stage IIIC breast cancer is a tumor of any size that has spread more extensively and involves more lymph node invasion.
Stage IV breast cancer is defined as a tumor, regardless of size, that has spread to places far away from the breast, such as bones, lungs, liver, brain, or distant lymph nodes.
