<s>[INST] My Mom was treated with Gastro Intestinal Stromal tumour a couple of years back and she was taking medicines for 1 year. Now he had stopped all medications completely but going for check-ups once in 6 months. In the very recent Ultrasound taken, it was observed that she had Fatty Hepatomegaly with liver size 157mm. Could this mean something related to the tumour again? [/INST] unlikely to be related to new tumor. CT scan or MRI would be better than ultrasound to pick that up.Your mom was probably given a medication called Gleevec, this can cause liver damage. She should get blood testing and close follow up. No alcohol and weight loss advised </s>
