The American Joint Committee on Cancer classifies
cancer in 7 major stages:
- Stage 0: Cancer cells are in their
original location within normal breast tissue.
- Stage I: Tumor does not have a diameter
wider than 2 cm and it did not spread beyond the
breast.
- Stage IIA: Tumor has a 2 to 5 cm diameter
that did not spread to axillary (armpit area)
lymph nodes or the tumor has a 2 cm size and it
spread to axillary lymph nodes.
- Stage IIB: Tumor is 5 cm in size but did
not spread to axillary lymph nodes or the tumor
is 2 to 5 cm size and spread to the axillary
lymph nodes.
- Stage IIIA: Tumor is smaller than 5 cm,
but spreads to axillary lymph nodes connected to
other nodes or to other structures or tumor is
larger than 5 cm and it spreads to the axillary
lymph nodes.
Stage IIIB: Tumor extended over the breast
tissue to the skin of the breast or the chest
walls, or it spreads to the lymphatic nodes
