[|Human|] My 7 yr old son has a marble size lump on the outside of right cheek. It moves up and down but is not painful, more irritating. I am unsure how long the lump has been present. I felt the inside of his mouth and could not find any cheek bite. Is this serious? What should I do?
[|AI|]  Hello, Thank you for consulting with Chat Doctor. As you are mentioning that you have noticed a lump in your sons cheek, it looks that it is a buccal lymph node which is palpable. As lymph node is a normal finding it is situated in different parts of the body. They are situated inside the skin, firm in consistency, movable and marble sized. So there is nothing to worry about it, you just notice it and if it starts becoming painful or increasing in size then consult a physician. Hope it will help you. Thank you
