<s>[INST] I work with a four year old girl and her tummy has a lump sticking out from her tummy button. Could it be a hernia? I don t want to say anything to her parents unless I have an idea what it could be. I can then ask about it. They might have already checked it out. Thank you [/INST] HiIt looks like Umbilical hernia. It has to be operated. Please consult your doctor and get an Ultrasound abdomen. Once the diagnosis is confirmed, it can be managed easily Wish her good health. Regards </s>
