Colon cancer?

i have bowel change now the last 2 months for no resoon with adomeal pain and one had red blood srikes on out side of stools
my stools do be diffrent all the time but mostly loose plus have a lot of stomach burn had an ultra sond done last week all ok

An ultrasound is not the test for colon cancer. A colonoscopy is the test for colon cancer.
If you are 50 or over this test should have been done.
I am a colon cancer survivor for 6 years now. I had the same symptoms you have and was very anemic. The Drs told me I probably had colon cancer for over a year. It is the silent cancer.
Go to a Gastroenterologist..

I would go for a second opinion of which you are entitled.

Good luck and take care
The test have proved that you have not got colan cancer, not to many vindaloo,s going down the hatch is it.??
You could have a liver condtion as well, go for a second opinion and also try and see a homeopath for an alternative solution.
There are more than one reason why you can get any of the better known symptoms of colon cancer. If the scan showed nothing suspicious, you are still entitled to ask why you are showing the symptoms described and what you can do about it. If you still have doubts, then ask for a second opinion. But please don't rely on an internet forum for medical help - your GP is by far the best person to deal with it.
Go to see a specialist.
My mum was operated for colon cancer and after 7 years developed the symptoms you describe. Had several ckecks including colonscopy and a full scan. No cancer. The reason was gastrytis and hemorroids. Maybe it's the same in your case.
