This disease forms in the cells that line the wall of the large intestine. The latter consists of the large intestine, which absorbs excess water and nutrients from digested food, and the rectum, which pushes the remaining waste out through the anus.

Once it reaches the nearby lymph nodes, the chances of survival drop to 70%… to drop to 13% once it has spread to other organs.
