Understanding Your Stage of Anal Cancer
The TNM system is a standard system for describing the extent of a cancer’s growth. This system was developed by the American Joint Committee on Cancer and the International Union Against Cancer. It is the most common system used to stage anal cancer. Here’s what the letters stand for in the TNM system:
M (metastasis) refers to whether the cancer has spread to other, distant organs in the body, such as your bones, liver, or lungs.
Stage groupings of anal cancer
Once your T, N, and M stages have been determined, this information is put together in what is called stage grouping. This is used to determine your overall disease stage. Stage grouping uses Roman numerals going from 0 (the earliest stage) to IV (the most advanced stage):
Stage III. The cancer has spread to lymph nodes in the rectum, groin, or abdomen, or to nearby organs, such as the vagina or bladder.
