This diarrhea is a sign of cancer. It has been diarrhea for nearly 30 years, about twice a day.

Under normal circumstances, if your digestive function is good, or the diet is easy to digest, then two bowel movements a day is a normal phenomenon. This is not a sign of cancer, you do not need to worry too much. If you are still worried, then it is recommended that you go to the hospital for further colonoscopy.
