My wife has a mass, they say is around some blood vessels. Don't know if it is cancer yet or not. They told us, if it wasn't cancer, there was nothing they could do. Is this true, or do we need a second opinon? She has to have a second bio, the 26th. This has been going on now, for 6 months. She has lost 35 lbs, in the last 3 months. Help,,,,, Their going to let her die,,,
