How Many Stages Are There In Colon Cancer?

Stage 0 Colon Cancer

This stage is considered a non-cancerous stage that has the tendency to progress to the cancerous changes. Generally, stage zero means polyps or small abnormal growths inside the colon or rectum. These polyps are usually formed in the lining of the colon, a tissue known as mucosa. At an early stage, these abnormal outgrowths are restricted to one place, and no further spread has observed in the surroundings. This is termed as “Carcinoma in situ”. They should be removed immediately when observed. If not treated at an early stage, they may turn into cancer cells.
