I have another ulcer coming out right next to the original ulcer. is this a sign of oral cancer, or are we just being paranoid?

Internet Diagnosis: It is not prudent to diagnose any lesion over the internet, sight unseen, without a complete medical history. It would be best to have those lesions examined by an oral surgeon, just to be sure.

Not uncommon: Canker sores is the most common recurrent oral lesions. Most ulcers, infections will clear up by themselves within a week or two. You should see your GP or dentist if the ulcer gets worse or lasts for longer than 2 weeks.
