Dear Doctors, My name is Medo, iam 28 years old, male , single with no any medical history. I suffered from white patches on both sides of my tongue since one year ago. From two months ago i found some big Taste papillae if we can say, on the back of my tongue, on both side on the edge. So i have white patches on both sides of my tongue since one year and enlarge papillae on the both side in the back of my tongue. Can you told me if this is a symptoms of cancer.
