I recently had a schwannoma removed from the median nerve in my hand. because i had one, does that mean i am at risk for more?

Multiple schwannomas: Multiple schwannomas can be present in certain conditions, such as, neurofibromatosis. It might be smart to have a thorough exam with a neurologist.

Solitary Tumors: Most schwannomas are solitary tumors and it is unlikely that there will be additional tumors unless you have a hereditary variety. In cases such as neurofibromatosis, multilple tumors are present but relativley few are symptomatic even though many may be cosmetically visible.
