How Many Stages Are There In Colon Cancer?

Stage I Colon Cancer

This is the actual stage where the cancer starts developing. In this stage, cancer spreads into the mucosa which is the internal lining of the colon and may also involve submucosa. If not diagnosed and treated at the submucosal level, it has also the tendency to spread to the muscles. This stage is written as T0 or T1, depending on the size of the tumor. As there is no proof of tumor spreading into the lymph nodes and other organs surrounding the infected part, TO or T1 is usually accompanied with N0 and M0.
