What are the different stages of breast cancer?

Stages 0 thru 4: Stage 0 is cancer confined to the ducts or lobules. Stages 1 describes a small cancer without lymph node involvement. Stage 2 is where the cancer is medium sized and/or involving lymph nodes. Stage 3 is associated with cancers that are large, involve the overlying skin or chest muscles, or contiguous nodes. Stage 4 describes distant organ involvement called metastases.
