Fiber is supposed to decrease colon cancer risk, but does chronic constipation increase the cancer risk even if a person eats tons of fiber?

Colon cancer. The relationship between high fiber intake and colon cancer is still somewhat controversial with studies going both ways. But a high fiber diet is beneficial in many other ways as well. There are no quality clinical data to suggest constipation is a risk factor for colon cancer.
Unlikely. A diet low in fiber is associated with colon cancer risk. Constipation has not been associated with increased cancer risk in huge population studies in japan and netherlands recently- in fact in the latter study colon cancer risk was less in patients with constipation!

Not anymore. Polyps are benign if removed early like you have done. Only if you neglect them and let them grow, they can change into cancer. You should be fine, but your doctor would likely advise you to have repeat colonoscopy every 5 years or at least every 10 years because there is small risk of developing new polyps. But there is no reason to worry about cancer as long as you are having colonoscopy as advi.
Talk to your GI doc. The prevalence of cancer in these lesions may be as high as 5-16%. If the GI doctor removed the polyp with negative margins you will need surveillance with colonoscopies (time intervals determined by your GI doctor) to make sure that if you get more polyps later on, they are detected and removed early (before they turn into cancer).
