[|Human|] Hi, my step dad is 76, he was diagnosed last year with stage 4 cancer, tumor in the pancreas, in the lung, spots on the liver, and surgery  at the same time for cancer in the hip, putting a steal rod in, followed by radiation. They were going to do radiation on the brain, after the hip, but decided not to on the brain. He has a non currible cancer, treatable, but fast spreading, he just found out today he has 3, 3cm tumors on the lung, 1 effecting his esaughagus, which is causing him to have trouble swallowing and breathing. He will recieve a double wammy of chemo on Tues. When would a Dr. stop chemo? My dad would never tell the drs if the chemo made him sick, thats why he is getting strong doses. He has been sick everyday in the last year.
[|AI|]  Hi, Thanks for writing in. Pancreas cancer is a challenging condition and survival depends on the stage of detection. In most patients having stage 4 cancer the survival can be extended up to 2 years with recommended treatment and supportive care. Your father has a stage 4 disease and therefore requires chemotherapy to extend his survival. Since the cancer has involved the pancreas and also seen in esophagus, liver and lungs, unfortunately he might be in the final stage of disease. The fight against cancer is till the end and if his general condition permits then his chemotherapy can continue till he is able to withstand the treatment. His pain relief also requires attention, and he must be allowed sufficient pain relief medicines and live in comfort. Please do not worry.
