Possible. Throat cancer in the pediatric age group is possible, but rare. Symptoms might include difficulty or pain with swallowing, a rapidly increasing mass, difficulty speaking, difficulty breathing, drooling, persistent and/or worsening throat pain.
Yes, but unlikely. It is entirely possible, especially if that person engages in unprotected oral sex with someone with hpv. Symptoms would be along the lines of difficulty swallowing, pain with swallowing, regurgitation of undigested food, throat pain, and hoarseness. Not all of these would happen in every person, so it depends on where the cancer is located and how far it has spread.
