Dad's cancer

In October 2016 my father went to the ER with a complete bowel obstruction. He had years with loose stools and blood on us stool too but he ignores the signs until it was necessary. He got an emergency surgery that day after receiving news that the mass found was cancer. He has an irreversible colostomy. The cancerous mass was the sizes of a man's fist. We never had an actual staging for the cancer, but it hadn't metastasized at that point. As soon as his surgery healed, which ended up being almost 3 months, he started radiation and a low dose of chemo in late 2016 for about 6 months, every week. He had little complications, other than a little over drying of the skin on his buttocks. For the next months, until December 2017, he got chemo, 3 types. Once a week, combinations. I'll look for the exact names in a little since I tried to keep things documented. During all this, he didn't qualify for any sort of medical aid and most expenses were out of pocket. We managed, somehow, but they did some blood work in March and they scheduled him for a stomach CT scan consequently. Prior to march, he had an MRI in december that said everything was ok. CT results show a new spot on his liver, and a "rapidly growing"  black spot in his stomach. He also has a bad pain in his leg that won't go away. My dad is 52, no other health issues. He is taking this hard and has given up. He feels he is going to die, and I'm taking things rough. I'm an only child and I am not losing hope. New here and looking for a shred of light.
