Gary Munoz stage 3 lymphoma treatment

My grandpa has recently been diagnosed with stage 3, fast-growing B-cell Lymphoma. My family is stressing out about treatment costs considering he will have to do chemotherapy and other intensive care. Considering my grandpa will be out of work and we aren’t very well off to begin with, our family would appreciate an olive branch to help with bills and treatment. 

thank you everyone, every little bit helps
