my dad is 72. diagnosed with lymphoma of the abdomen in Sept. had 4 chemo treatmenst. all the tumors have shrunk except the ones around pancreas. had to have a stint in the bile duct. no tumor. they say he has a dark spot on the pancreas. the nodes around the pancreas have actually grown thru the chemo. his dad died of pancreatic cancer. he belly was distended very badly in September and was in a lot of pain. the day after his first treatment the paid was gone. the belly gradually went down. im worried he too has pancreatic cancer. is this common with lymphoma?
