Brother has Stage 4 colon cancer

Hi, my name is Dana. My brother, Walt, was diagnosed with Stage 4 colon cancer about a month ago. They removed a tumor from his colon along with some of his colon and intestines. It has spread to his lymph nodes and liver. Before surgery, he lost over 50 pounds in a month. His insurance barely covers anything. He has to gain at least 30 lbs to hopefully start chemo. He has to eat A LOT to fight the calories burned from the cancer growing. We need help with food, medical supplies, and medical bills that his insurance won't pay for. He also has severe psoriatic arthritis so he is in a great deal of pain. We have applied for disability and medicaid but that could take several months. If anyone could help, we would be eternally grateful!
