curious if both your parents smoked?
I think that the issues would be separate...but creatinine levels should be checked if one is on 5ASA meds, regardles...that and of course liver enzyme levels.
There are also some cancer marker tests that you could have checked if you're concerned. Now, not all positive markers state one has cancer, as do a negative marker state one doesn't. They are helpful in diagnosis, or to alert
if other tests would have to be done.
Have you done any research into the causes of kidney cancer? You might be able to get in with the doctors who have dealt with your parents to possibly do some tests to help in your worries.
If you haven't had any kidney enzyme tests done as of yet, you should enquire about
it to your GI.
