Re: oral cancer?
How many lumps do you have? Do you have any risk factors for oral cancer? What size, etc.? I'm not sure whether they are on your gums or on the skin inside your lip, or both, or otherwise. Given your description, I think this is some sort of benign condition. However, it is definitely something you should have checked out by a physician or dentist. Hey, you should have your teeth cleaned twice a year anyway, and dentists can perform a really good evaluation for oral cancer, so... have it checked out.
