Hi there, Thanks for your query. You have not mentioned if biopsy was taken; whether the tumor was found as cancerous or non-cancerous. Continue with Glivec for 12 weeks, followed by a CT scan of stomach. If there is a satisfactory response to Glivec, it may be continued further. To reduce your stomach symptoms, I suggest that you take very small frequent meals, every 2-3 hours. In addition, there is always iron and vitamin deficiency due to affected absorption. Injectable Iron and Folic Acid + Vitamin B12 should be taken regularly, as per your doctor s advice. Also, regular Probiotics and digestive enzymes will help. Consult your doctor and apprise him of my opinion. I am certain that he will agree with me, order required tests, and- based on the reports- will prescribe suitable/modified treatment as advised.
