Stage 2 breast cancer is considered to be relatively early, with minimal spreading
Stage 2 breast cancer is an early stage breast cancer that is growing. It can be 2A or 2B. 2A involves no tumor, but no more than four cancerous lymph nodes under the arm. 2B is a tumor that is less than 5 cm and has either less than 4 lymph nodes under the arm or clusters around the breastbone. Stage 2 cancers are larger than stage 1, but they are still pretty easy to treat. Most treatments involve surgical removal of the cancerous mass followed by chemotherapy and radiation to eradicate anything left behind.
