What other complications may occur with rectal cancer?

1. Colon obstruction

It is one of the late complications of rectal cancer and can occur suddenly or gradually. It is usually caused by tumor proliferation blocking the intestinal cavity or intestinal cavity narrowing, or by acute inflammation, congestion, edema, bleeding, etc. at the tumor site.

2. Intestinal perforation

There are two types of rectal cancer with perforation: perforation occurs locally in the tumor; proximal colon perforation is a complication of tumor obstruction. After perforation occurs, clinical manifestations may include diffuse peritonitis, localized peritonitis, or local abscess formation. Diffuse peritonitis is often accompanied by toxic shock, and the mortality rate is extremely high.
