A member asked:

Are all blood blisters of mouth cancerous?

A doctor has provided 1 answer

No.: Most blood blisters are not cancerous. Sores or blisters in the mouth usually go away on their own. If they persist for more than 3-4 weeks, then you should have them checked out. Otherwise, they are nothing to worry about.
