question about possibility of colon cancer/colorectal cancer

[Guest guest]

I have had problems these past couple of months with frequent bowel

movements, so much that i started to bleed. I went to the doctor last

week and he gave me amoxicillin. It hasnt helped and i saw another doc

today. She gave me a suppository to clean out all the feces. Im

suppose to be going in on wednesday for a barium enema. From what i

understand they usually look for colon cancer, or inflammatory bowel

diseases. Does anybody know what type of symptoms i should really be

concerned about? I have had diarrhea,blood,mucus,swollen tonsils,

feeling like i want to vomit almost all the time, fatigue,some

abdominal pain but very little. I felt like the last doctor i saw

didnt take me seriously because of my age. Is there anything else i

should be looking for? I also took the suppository at 11 am and now i

have had only one bowel movement, before i took it i had about 5 bowel

movements, i did see some white discharge come out, does that mean i

did not push in the suppository far enough? thanks for any help, if

anything please tell me who i can ask. thank you.
