[|Human|] Hello, I have a son that is going to be one on friday.. I have notice that one of his buttcheeks is larger than the other for a while. I have taken him to the doctors and done test. they say its fat tissue, but i think differently. Today i was giving him a bath and i wash by that cheek and push down on it a little harder than i normally do and he seems more in pain. He does not sit straight in highchairs, shopping carts and ect. What do you think it is? Do you think its cancer? Please help
[|AI|]  Hi, It seems like you are too worried. It is quite common to have subtle asymmetry between two sides of our body parts on close observation. As your doctor said, it is because of the difference in amount of fat tissue beneath skin on both sides. The pain is caused by undue pressure. This an extremely rare site for cancer in child Chat Doctor.  Since he is totally asymptomatic and your doctor has reassured you after examining, you need not worry, just be relaxed. Hope I have answered your question. Let me know if I can assist you further.
