I Recently Saw My Dr For An Annual Checkup. Im

i recently saw my dr for an annual checkup. Im 39 years old. I asked my dr about some kind of bulge on my lower testicle on the back side where the tubes up to my gut connect. He told me its nothing to worry about. So I had to do my first colonoscopy. They found 30+ pollups. The gastro intestinal dr that did my cleaning said because of the many pollups I would need to get tested for Lynch Syndrome.
Is that true? Should I be worried about my lower right testicle?
