A stage II breast tumor is larger than a stage I tumor, but the cancer hasn't spread to a distant part of your body. If your cancer is stage II, one of the following is true:

  • The tumor is 2 to 5 cm (3/4 to 2 inches) in diameter. The cancer may or may not have spread to your underarm (axillary) lymph nodes.
  • The tumor is more than 5 cm (2 inches) in diameter — about the size of a lime — but the cancer hasn't spread to your axillary lymph nodes (A).
  • The tumor is less than 2 cm (3/4 inch) in diameter, but the cancer has spread to no more than three of your axillary lymph nodes (B).
  • No tumor is found in the breast, but breast cancer cells are detected in no more than three of your axillary lymph nodes.
