Pre-cancer cells are only in the mucosa the layer of cells lining the inside of the anus and have not started growing into the deeper layers Tis. It has not spread to nearby lymph nodes N0 or distant sites M0. It has not spread to nearby lymph nodes N0 or to distant sites M0.
The cancer has not spread to nearby lymph nodes N0 or to distant sites M0. Stage II: The tumor is larger than 2 cm and has not spread to the lymph nodes or other parts of the body T2 or T, N0, M0. Stage IIIB: The tumor has invaded other nearby organs, but lymph node spread is limited to the area around the rectum; there is no distant spread.
Or, the tumor may be of any size; lymph node spread can be local or distant, but there is no disease spread to distant organs T4, N1, M0; or any T, N2 or N, M0. Stage IV: The tumor may be any size and has spread to the lymph nodes and to distant parts of the body any T, any N, M1.
Recurrent : Recurrent cancer is cancer that has come back after treatment. If the cancer does return, there will be another round of tests to learn about the extent of the recurrence.
