sunny, doc is telling you the real deal, the groin is full of trash, bad spot for lymphoma biopsy. Get a new dr and find out or try to find out your dx. I am pattient at ***CC Hou,Tx and before I got there I was put through a nightmare. Mine is a difficult case and primary site still unconfirmed but I am in the best place for help. If you have lymphoma it can be anywhere, not just lymph system. My biopsy of lymph node from neck, chest and the thymus gland were dx with severe hyperplasia. I am in a lot of bone pain and also pain in my spine is real bad and onc feels my lymphoma is organ related some where!
