Symptoms of colon cancer with sime nausea with little pain constipation for almost 2 years?

Possible : Colon cancer may be discovered incidentally (eg, colonoscopy screening), or may be manifested by microscopic or macroscopic blood in stool or more concerning features suggesting impending bowel obstruction such as progressive abdominal pain, distension and failure to evacuate stool.

What am I missing?: It certainly sounds as if your symptoms are deserving of a complete evaluation with a physician. This can start with a thorough physical examination, including a rectal exam that can check for blood in your stool. Your doctor can determine if a colonoscopy is warranted.
