Hi @Blackkitty25, of course you're nervous about the appointment. I would be too. Welcome to the forum. Feel free to pose any questions that you have, bearing in mind that advice is of a personal nature, not medical.
I don't specifically remember hearing of anyone on here with Lynch syndrome, but if you enter it into the search bar on the home page, you may find something.
There are other hereditary cancer genetic links. All are scary, and the only good thing is that it gives you knowledge of what you may need to look for.
@kmakm, @primek, any words to help?
Take care
