Help with my Grandfather’s chemotherapy treatment

As many of my close friends and family members know, my Poppop was diagnosed with lung and colon cancer recently. He has finished his radiation but unfortunately my grandparents cannot afford chemotherapy. The out of pocket cost will be $1300 every two weeks until his deductible is reached. My grandparents are on a fixed income and are struggling to pay hospital bills. Any donations will be greatly appreciated by my family and I!
