Save Suzy from Melenoma

Suzanne, my sister, has stage 3 melenoma and needs an Immunotherapy (something like chemo) called Yervoy, and her copay is $11,000.00 per dose and she needs 4 doses.  Melenoma does not respond to "normal" chemo or radiation therapy and this is her best shot at a cure. I would never ask for help under normal curcumstances but this amount of money is devastating and it is her only option. She needs to start this now so any help will be greatly appreciated.
