Is it possible to have two types of primary cancer? biliary tract and thyroid?

Yes but rare: Bile duct cancers are very rare-esp in this age group. Even thyroid cancer is rare in this young group , but does occur. If you have a thyroid nodule greater than a centimeter, usually we do a needle biopsy. Gallbladder problems at this age are more likely related to gallstones.

Yes, unfortunately: Yes it is possible to have two or three different types of primary cancer. If that is the case one should really think perhaps there is an underlying genetic mutation . I have a couple of patients who have 4 different primary cancers.
