Hello friend, You have to undergo medical consultation at the earliest. A gastro enterologist is the specialist you have to approach at first. If he suggests thereafter you may have to consult a general physician also. You have to do an ultrasonography test to identify the nature of the tumour you are having at the left side. Left lobe of the liver, stomach and spleen are the abdominal organs situated in the left side of abdomen. The result of the investigations will give you an idea about the swelling and the reason for your wasting. Thereafter you can approach an expert Homoeopath for curative treatment. I can also help you if you can get back to me through the personal query facility of healthcare magic. With best wishes, Dr C. J. Varghese Homoeopath
