<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hello, the last few days my stomach fat to the left of my tummy button has been hurting, almost like a bruise when I press on it or rub my hand across it. Is there a simple explanation for this and if not should I get it checked out as there is history of polips and cancer in my family..  <response>: Hi! Thanks for your query which is a common question in my clinic. Well there are few possibilities in your case just you described as almost as a bruise when I press on it or rub my hand across it... as follows:1. An epigastric hernia 30 possibility2. A lipoma 30 possibility: lipomas are painless, soft to firm mobile subcutaneous well-defined nodules; sometimes associated with severe burning pain.3. Benign skin tumors like neurofibroma, dermatofibroma etc.: 20 possibility4. Just psychological feeling : 15 possibility5. Lymph nodes and cancer: 5 possibilityTherefore, I must suggest you USG and if necessary a needle biopsy for confirmation and to discuss it with your surgeon if treatment is needed. Regards,
