In brief: 5 (zero thru four)
The stage of breast cancer is based predominantly on the size of the cancer and lymph node (ln) involvement.
Stage 0 is pre-cancer (carcinoma-in-situ); stage 1 is small cancers +/- microscopic ln; stage 2 is larger cancers+/-overt ln involvement; stage 3 is cancer involving the skin or chest wall+/-many lns or those away from the armpit; stage 4 is cancer elsewhere in the body (metastatic disease).

In brief: Four
Stage i and ii are called loco-regional (confined to the breast and the axillary area) and stage iii and IV spreads to more distant areas.
