What is breast cancer?
- Breast Cancer is a malignant tumor that grows in one or both breasts and usually develops in ducts or lobules (milk producing area of the breast).
Two main categories of breast cancer:
- Noninvasive cancers: confined to the ducts or lobules and does not spread to surrounding tissues.
- Invasive cancers: penetrates through normal breast tissue and invades surrounding tissues.
Stages of breast cancer:
- Stage 0: early stage confined to ducts or the lobules.
- Stage 1: early stage of invasive breast cancer. Cancer cells have not spread beyond breast and tumor is no more than 2 centimeters across.
- Stage 2 is one of the following:
-tumor in breast is no more than 2 centimeters across. Cancer has spread to lymph nodes under the arm.
-tumor is between 2 and 5 centimeters and may have spread to lymph nodes under arm
-tumor is larger than 5 centimeters and has not spread to lymph nodes under the arm
- Stage 3: may be a large tumor, but cancer has not spread beyond breast and nearby lymph nodes. It is locally advanced cancer.
-Stage 3A is one of the following:
~tumor is in breast and is 5 centimeters. Cancer has spread to underarm lymph nodes.
~tumor is more than 5 centimeters and has spread to underarm lymph nodes
-Stage 3B is one of the following:
~tumor has grown into chest wall or the skin of the breast.
~tumor cancer has spread to lymph nodes behind breastbone.
-Stage 3C: tumor of any size and has spread to lymph nodes behind breast bone and underarm or has spread to lymph nodes under or above collarbone.
-Stage 4: distant metastatic cancer and has spread.
