<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi,My aunt was suffering from massive stomach ache since the last 3 weeks. She has high Blood Sugar as well. We consulted an MD suggested that we do a blood test to check the sugar level. The sugar level is high at 300. We then consulted another doctor he asked us to do an ultrasonography, which we have done he said it Gall-Bladder stone but he wouldnt be able to operate until the sugar level is low. He suggested Insulin. Again after that he suggested us to do a CT scan.When we showed the reports to him, hes suspecting Cancer asked us to visit an oncologist ASAP. My aunt has become thinner by day cant have food properly. Please help as to what to do.  <response>: HI. Thanks for your query and an elucidated history. Aunt has pain for 3 weeks and the ultrasonography is suspicious of cancer. You should undergo CT scan and preferably MRCP. A guided biopsy may be needed. Once confirmed to be a cancer surgery may be an option or a chemotherapy depending upon the diagnosis. She should be admitted and started with Insulin so that she is perfectly under control of diabetes which is most important.
