I am a 36 yr old male.

I have had rectal bleeding for about 7 years now. On and off, more on than off. When I first had it, I went to the doctor who told me I had internal hemorrhoids, (he said they were hereditary because my dad and mom both have them) and basically told me to watch my diet, eat more fiber etc etc. Now I didn't have any other symptoms, no pain, no bloating, no vomiting etc, just the bleeding in the toilet every time I went to the bathroom. Sometimes it would last about a month then go away for a week then come back etc.

Recently during a doctors visit, I was told that my hemoglobins were high and that I was anemic and to start taking some iron pills. I went to see another doctor who basically started worrying me about colon cancer and that I needed a Colonoscopy etc. Now I am really freaked out and can't think about anything else but this impending Colonoscopy and if I have colon cancer. I have read about the symptoms and despite the bleeding and the anemic, I have no other symptoms, no pain, no vomiting, no bloating etc etc. How realistic is it that I have colon cancer.

Thanks for listening to me.
