After 40 minutes I was finally called in. This guy didn't automatically rule out surgery, but he was trying to convince Warren he didn't need surgery. He also set up another appointment in a month for us to come back after he'd reviewed all the tests.
I think this guy is stalling us and trying to con Warren into thinking he's supposed to be condemned to suffer. He told Warren there's a 10% chance of further complications after surgery, but didn't give the odds on hemorrhaging without it (which he said could happen). He also denied the cyst had grown without looking over the write-up of the original MRIs the HMO had destroyed from ten years ago.
