Breast Cancer Stages
The following is a brief descriptions of the different breast cancer
stages as well as some of the more common treatments used for each
breast cancer stage.
Breast Cancer Stages: Stage I & Stage II
Stages I and II are the early stages of breast cancer. In stage
I the cancer cells have not spread beyond the breast. In stage II,
one of the following has occurred: the tumor is less than 1 inch
across and has spread to the lymph nodes under the arm; the tumor
is between 1 and 2 inches across with or without spreading to the
lymph nodes under the arm; the tumor is larger than 2 inches but
has not spread to the lymph nodes under the arm.
For these early breast cancer stages, breast-sparing surgery followed
by radiation therapy is often used as a primary treatment. In addition,
chemotherapy and/or hormonal therapy, called adjuvant therapy, may
also be given to try to destroy any remaining cancer cells and to
prevent the cancer from recurring.
Breast Cancer Stages: Stage III
Stage III, or locally advanced cancer, means that the tumor in the
breast is more than 2 inches across and the cancer is extensive
in the underarm lymph nodes or has spread to other lymph nodes or
tissues near the breast.
Many patients with stage III breast cancer will have both local
and systemic treatment to remove the cancer and stop it from spreading.
The local treatment may include surgery as well as radiation therapy.
Systemic treatments may include chemotherapy or hormonal therapy.
Breast Cancer Stages: Stage IV
Stage IV breast cancer occurs when the cancer has spread from the
breast to other parts of the body. This is called metastatic breast
cancer. Women with stage IV breast cancer often receive chemotherapy
and hormonal therapy along with surgery and radiation. Radiation
may also be used to control tumors in other parts of the body.
