 [ Symptoms ] small pea sized lump in my cheek about a year ago i noticed a lump in my cheek it is on the right side and it is inside my cheek meaning it is not in my mouth it is in my skin in my cheek it is not painful and it is about the size of a marble it is grown since i first noticed it it is moveable and it is not painful it feels hard and dome shaped i am 15 and my ent is sending me to get an ultra sound to figure it out  what could this be could it be cancerous could it be a salivary glad thing [ Disease ] most helpful answer it may just be a sebaceous cyst the ultrasound may show it or it may just have to be removed by the ent to get a diagnosis the chance that it would be a cancer is extremely unlikely this is just a guess since i have no way of examining it first hand and your description is just to vague to blindly offer any type of a definitive answer
