[|Human|] I ve had diarrhea for two solid months; it started suddenly. all blood work and stool tests are normal (with exception of lipase.)Primary found a lump on my colon, ct. looked normal.(small cyst on liver) Constant bloating, gas and pain along with distended stomach. Any ideas?
[|AI|]  Hello! Thank you for the query. Lump in the large intestine should be verified with colonoscopy. It can be a polyp however colon cancer is also possible. Especially if you are older than 50. Bloating, diarrhea, distended stomach clearly indicate partial bowels' obstruction. It can be caused by colon cancer. So please do not ignore it. Visit your doctor and have colonoscopy done at first. If it shows nothing, stool tests should be done next. Hope this will help. Regards.
