Pain from obstruction

Some people with cancer have pain in the abdomen caused by a blockage (obstruction) of the gastrointestinal (GI) tract--the stomach, intestines, and colon.

GI obstruction is more common in people with ovarian and colorectal cancer, but any tumor that starts or spreads to the abdomen could result in GI obstruction.

The tumor, growing either inside or outside the bowel, may completely or partially block the bowel. Scarring (adhesions)--from previous surgery, radiation, or the spread of the cancer inside the abdomen-- can also cause GI obstruction.

GI obstruction is sometimes treated by surgery, but can often be managed medically--mainly with medications that relieve pain, stop colic, reduce nausea, and dry up secretions.
