Patient :I have what appears to be a mouth sore on the roof of my mouth but I'm sure its been more then just a week or two (the average time for a mouth sore to go away) is there any way I can rule out cancer without going to the doctors office?
Symptoms: Sore on the roof of mouth. Also I don't know if its related but I have been having some joint pain and discoloration in my knuckles.
