Help Cleveland (my dad) get surgery (Lyposarcoma)

Hello! My dad (Cleveland Canova) will be having surgery to remove an 11-inch cancerous tumor from his abdomen, along with parts of his kidney, colon, gallbladder, and liver (small area) on the 22nd of March. This surgery is not only expensive, but also extremely invasive and requires 4-6 weeks of rest and recovery. Although insurance covers most of the costs of the surgery, my dad will still be left with a $20,000 bill for just surgery (doesn’t include his stay in the ICU after the surgery). On top of this, he won’t be able to work until he’s completely healed. Any help is greatly appreciated, especially if it helps my dad in a stress free and speedy recovery…anything at all helps! Thank you so much and God Bless!
