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
located on the chest walls along the sternum.
Stage IV: Tumor can have any size that spreads beyond the breast
region and chest wall affecting the lungs, bones, or liver.
