<s>[INST] Hello, I am the mother of a five year old, when my son was born he had a small lump on his stomach the doctor said it was a grease bump and that in time it would go away. Today he is 5 and the bump still exists it is about the size of my thumbnail the doctor says there is no need to worry should i take him to a dermatologist?? No pain and never fuses about his bump but to me it seems abnormal for him to have this [/INST] Hi. Thanks for your query. I can understand the anxiety a Mother can have with any problem for her son. Grease bump is one thing that should not be worried about. Just to reduce your anxiety, it would be better to have a consultation with the Dermatologist, get the bump removed and investigated by histopathology examination and you both will be happy and tension-free. Why to keep something lingering that bothers you the most. I hope this answer helps you in proper decision-making. </s>
