Hi I recently had a ct scan and they said they seen a mass on my colon does that 4 sure mean cancer?

I had same thing I'm 22 now I was 18 he told me he thought it was cancer so off my experience I'd say they'd have done the same. Turns out I have BAD scar tissue binding everything together and a apparent rare issue which means my body makes FAR to much bile which leaks into my bowel causing adenomas and pre cancerous growths and acts like a laxative and has (possibly) contributed to me being very early chrons disease stage. Honest in my opinion don't worry until you know. 4 years I've had several colonoscopies endoscopes Mri X-rays scans nuclear tests and unless they say they're worried I'm not worried. What I have to do is get checked via stool samples ALOT to measure my calprotectin ( inflammation in bowel ) and when it gets high then they can finally diagnose and act. I hope you have the same outcome. I was told I had abnormal mass on a colonoscopy. They worded it HORRIFCLY. It was an adenoma. Tiny tiny thing. I see mass as a huge thing but apparently not in dr terms. I hope you are ok 

So I had my follow up today. So super scary he said my polyps were precancerous and said that 4cm one could have changed anytime within days or months I'm not sure who was watching over me but I am so very thankful! I do have 2 go for another colonoscopy in 6 months to make sure that nothing has grown baxk and then after that he said prolly every 3 years but I don't even care if it's every year I'd probably feel more comfortable if it was every year. If anyone feels there is something wrong never hesitate go get checked I actually thought something was wrong with my pancreas and they came upon this I consider myself very lucky. Ty everyone for all of your prayers I am very thankful to everyone on this forum. I have made some friends on here that are very caring people.?
