Stage 2: Early breast cancer. The cancer may be no larger than one inch, but has spread to lymph nodes under the arm; or is larger than two inches, but has not spread.
Survival rate: 60 to 75 per cent
Stage 3: Locally advanced. The cancer can be smaller or larger than two inches and has spread to lymph nodes under the arm, other lymph nodes and even tissues near the breast.
