Colon cancer age 30?? RUQ pain, fecal occult test negative- CT- Normal- (GI tract WNL no obstruction or perforation) should I get colonoscopy for pain

Probably. Colon cancer is unlikely in your age group, but other GI and colon diseases can also cause such symptoms. Have you had your gallbladder evaluated? Remember, colon cancer has minimal symptoms and CT is NOT a great test for it. In sum though low yield I would likely recommend colonoscopy to you based on what I've read.
