[|Human|] I have six to seven red small lumps on my toungue at the back which I have had on and off for years. I believe they were caused by bushing my toungue which I do twice a day as they occurred around the same time. I have spotted what looks like an extension of one of these on the far left back of my toungue which is bigger than the rest which I ve only recently noticed. I am concerned this Kay be a growth- and lead to cancer. What is the best course of action?
[|AI|]  Hi! Had you gone back further, your concern would just increase! But I think you just examine any ones tongue these are there; just because these are not only normal, these are also very necessary part of our immunity system within the tongue! Yes, these are taste buds and submucosal collections of lymphoid cells to fight against any offending organism like tonsils; these could be red, brown, whitish, dark etc. in color depending on their reaction! Their number increases as backwards we go on the tongue. No chance of cancer; don't worry!regards!
