[|Human|] I am concerned about some lumps in my mouth that I recently noticed.  They are small lumps on the floor of my mouth, but seem to have gotten bigger and more noticeable since I noticed them about 4 days ago.  I have been chewing tobacco pouches on occasion (2 or 3 a week) for about 2 months now, and have been smoking an average of two cigarettes per week for about a year.  I am concerned that the lumps may be cancerous - how would I know?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. Possibility of cancerous growth is unlikely in your case. But since you are smoker and having habit of tobacco chewing, better to get done biopsy from the lumps and get done histopathological examination to rule out cancer. Smokers and tobacco chewers are at increased risk of oral cancer. So biopsy and histopathological examination is must in your case. Vitamin deficiency is common cause for such lumps in mouth. So if biopsy is negative for cancer than start multivitamin tablet containing folic acid, niacin, vitamin b12 and zinc. And in any case you need to quit smoking as well as tobacco chewing as soon as possible. Hope I have solved your query. Wish you good health. Thanks.
