My wife has a swollen growth at the side of tongue what could be responsible and what can cure it? regards and thanks in advance

Oral surgeon: Your wife needs to have the growth evaluated. It may be nothing serious, but it can be, too. Smoker? Drinker? All factor into equation. Please call asap for appointment, even if there is no pain. The longer you wait, the more tissue will need to be removed if it has to be excised.

See oral surgeon: It's hard to tell what is going on without seeing where it is, what it looks like, etc. I recommend seeing an oral surgeon and possible having a biopsy of the tongue.

Growth: The rule of thumb is that all pain and/or bleeding and/or swelling requires immediate evaluation. Benign oral lesions generally completely heal in 2 weeks or less. If growth has been there more than 14 days it must be examined to determine cause and thus appropriate treatment. Suggest a specialist Oral Surgeon, now.
