Worried about Colorectal Cancer!

First let me thank you for what you're doing here.  I'm 26 yr old blk male and for most of my life I've been in relatively good health and aside from my bowel problems I'm in good physical condition.

Beginning in the fall of 2000 started having bowel problems..I became constipated and could feel gas build up but had serious problem releasing it.  I visited a Gastroenterologist and told them my symptoms.  I was put on a fiber supplement and all my symptoms disappeared.  A few months later they returned, not as bad as before but they were there.  I visited the doctor again.  I was give a blood test(not sure exactly what they tested for) and I was informed it came out negetative.  Over the past 8-12 months my symptoms have gone and returned but now they are steady.  Though I no longer experience constipation or gas problems as long as I take the fiber supplement and/or eat a good number of fruits and vegetables.  I do experience straining with my stools at times and aggravation sometimes pain in my lower back and buttocks area.  This usually occurs after I take a stool and sitting seems to make it worse.  

Once thing that has been constant over this time is mucus in my stools.  Not with every stool but the majority, sometimes not much and other times it's very noticeable.  I have not seen any noticeable blood.  Another problem I have and I'm not sure if this is related is every so often after a stool in which I strain, semen comes out of my penis and I experience a pain there.  

I have been worried about colorectal cancer and wanted your opinion.  Thank you.

I was worried too.  That's how I came on this website today but after reading people's inquiries and seeing what they have done without any serious problems, I realize that my worry and perhaps your worry are for naught. It sounds like you have Irritable Bowel Syndrome.  I think that comes with mucous as does colitus.  Colitus is also a nervous stomach.  Sometimes you have to strain and other times it just comes out fast.  As long as your tests are good.  Don't worry.  If you eat lots of fruits and veggies and whole grains and not too much fat and beef you should be fine.  If you are so worried, have a colonoscopy.  If you don't like them invading you, have a Virtual Colonoscopy which is done with air.  If you can stick it out there is a new test coming out in a couple of years,  where all they will need is a piece of your feces and they will know whether you have cancer.  You can go through all sorts of scans as well, but it sounds like a nervous stomach to me.
