How and/or why does ovarian cancer cause feeling full / early satiety?

Spread inside the be: Ovarian cancer tends to spread all over the intestines , leading to their normal movement and normal functions. This is reflected in any form of digestive symptoms. There may also be fluid collection around the intestines which also interferes with their normal motility and digestive functions.

When it's too late: This is oversimplifying slightly. A very large ovarian mass can compress the stomach. This would have been found on pelvic exam. If you have any concerns about ovarian cancer, talk with your personal physician. Best wishes.
