Help fund cancer treatment for Dad

Dad was diagnosed with stage 3 colon cancer. He had surgery in July 2017 to remove the tumor but his lymphnode tested positive. He needs to do a 6 month round of chemotherapy to treat the possible remaining cancer cells in his system. His insurance is covering the treatment but his monthly copays are unaffordable for him. We have exhausted all other options to afford getting this treatment. Without your help, he will be unable to get this treatment. The last 3 years have been rough with Mom's death, his heart surgery last year and now this challenge. Please pray for him and keep good thoughts coming his way.
