Thank you sir, I'm so sorry to hear about your sister. The sad irony is that my dad started a foundation for brain tumor research 15 years before he was diagnosed... my sister-in-law had an inoperable brain tumor before graduating high school and was given six months to live. She passed away six years later, and the charity was my dad's way of fighting back. When he was diagnosed, it was already stage 4 cancer. It started in his abdomen as Neuroendocrine Cancer and spread to his brain. We lived through one year of hell on earth as he went from treatment to treatment, but 4 years ago today, his battle came to an end. He was 70 years old- we're thankful for the time we had with him and for people like you and the others on this forum who keep his memory alive!
