From February 22 nd stomach problem. Gone to many doctors but they tell it amebiasis or ibs. Now Feels like something is stuck in my anus like gas or stool. Poop is fine, no complaints regarding poop. But, Sometimes a little mucus comes with poop. And in sometime a found a little blood in that mucus. Blood's size like an ant. Gone to an gastroenterologist 2 days ago. He gave me librax tab. I don't drink or smoke. Tell me by any chance can it be cancer? Please I am afraid of colon cancer.
