Please help my father fight this battle

When my father was 19 years old, he had a very bad accident. His hair got caught in a machine and ripped from his eyebrows to the bottom of his neck off & his ear. They did skin grafts from his legs to replace the skin on his head. He was lucky to make it out alive from this accident. Since I was born my dad battled with always having sores on his head from the grafts constantly breaking open but he was always able to manage it. Recently, it got to the point where he could no longer save it. It created a massive hole in his head. A hole bigger than the size of my hand. When he was home one day, pieces of his skull had fallen out into his hands and his brain was completed exposed. A few days later he was getting ready to start his day, when he had a stroke. He woke up face down on the floor and had lost feeling in the left side of his body. As soon as my brother found him he called 911 and rushed him to the hospital. When they arrived at the hospital they sent him for a CT scan and when they brought him back in the wheel chair he had another stroke followed by a seizure and he fell to the hospital floor seizing. They took him to the icu and began trying to diagnose. They found a massive infection in his brain, along with cancer. Also a blood clot in his brain.  They have made the decision to do brain surgery. He is being transferred to Hershey medical due to not being able to find a doctor that is comfortable trying to do the surgery. My dad is my brother & i’s bestfriend and we are trying to do everything we can to keep him here with us for a much longer time. Any help is appreciated.
