Hi, i am 27 years old and i have noticed a swelling in my face it is not visible but it is a hard lump above my mouth and i can feel the sweeling under the tissues on the left side of my face around the nose and if i push my hand in the left nostril i can feel it at the base. I also discovered that hard swollen feeling in the roof of my mouth, exactly in the centre. It does not hurt at all but i am worried it may be oral cancer. i do not smoke and i drank occationally but not for the past two years. i got in into a car accident about six weeks ago, where i sustained injuries to the left side of my forehead did not appear that anything was wrong with my face, was just wondering if it could be as a result of the accident. please anybody who might have an idea. thanks in advance.
