I’m a 70 yo, Caucasian male. Also a diabetic, which is a result of exposure to Agent orange. I was a U. S. Navy Corpsman, 1968-69.I just had a fecal occult test, with a positive result. I am not aware of any other symptoms. I must say, I’m very nervous. I have an appointment in 2-wks , with a Gastroenterologist. I had a colonoscopy 7-yrs ago and had a polyp which was negative, benign. I was told by Dr that it was unnecessary to have it every 5-yrs, and have it every 10 yrs. Interested in finding out what could be other causes of a positive test result. Thank you for your anticipate response.
