Gamma Knife Radiation Costs

In August of 2015 my beautiful mother had a major brain surgery to remove tumors from the brain. She has suffered from migraines and illnesses for a long time. They finally found the reason behind those migraines. She had several brain tumors that had to be removed because they were cutting off her blood flow. However, they left two. The first one was not big enough to remove yet, the second was in a dangerous spot. They did not remove it because it could have caused a stroke so they continued to let them grow. We are back here again in August of 2017. The tumors have grown and will have to be removed. However, this will be a different type of surgery. She will have two sessions of gamma knife radiation. The radiation costs are outrageous. They will cost $50,000 each. She will also be put on multiple medications every month that are very costly. She is without health insurance so this is very much needed . She needs the treatment and the prayers and love from everyone. I'm sure this will never reach the funds that they need, but anything helps!! please share!!!
