intraocular melanoma

Hi my name is Barbara Cole woke up 6 weeks ago noticed my left eye vision seemed a little grey for lack of a better term . I thought it might be a cataract issue, turns out it wasn't. i was told it was an ocular melanoma. I was also informed I needed to go to Massachusetts Eye And Ear Hospital and receive charged-particle radiotherapy. Although insurance will cover some. its all the addons and copays that are destroying my budget. I'm hoping a few extra dollars will help me get the pre testing done. The insurance companies require a liver cat scan with a large copay to make sure I haven't developed liver cancer, so if you don't come up with that everything stops and essentially you die. Considering I haven't drunk or smoked in 40 years not really how I want to go, so any help would be greatly appreciated. Thanks for your time.
