You have not had . enough or appropriate genetic counseling with regard to Lynch syndrome 1 or 2, to which you are cecertainly entitled.

Not necessarily. You may have a higher risk of developing colon cancer if your uterine cancer was caused by a certain genetic mutation.

Patients with this have about an 80% chance of getting colorectal cancer and about a 50% chance of uterine cancer over their lifetime. Read more...

No. You've asked before, right? I'm not sure why you're concerned, but I also honor folks' intuition. It's an easy if perhaps slightly pricey genetic test. If you have decided what you'd do different once you have your answer, ask your physician about it. Read more...
