Colon cancer: You should have your stool examined to make sure this is not blood. If it is you will need an extensive evaluation for the possibility of cancer, but this is very unlikely at your age. Constipation is not likely responsible for your fever/headache.

Yes: Those symptoms are common with constipation. The likelihood of colon cancer at your age is low, but if you have had significant changes in your bowel habits or if you have significant family history of colon cancer you should consider a colonoscopy.
