Please Help My Dad Defeat Cancer

We recently discovered my father has malignant cancer. He went to the hospital and they dumped him back out a few days later with confirmed Parotid Salvitary Gland Cancer which is malignant. He lives in another state and as a product from his condition he's living in his van under the hot Arizona sun. We are trying to collect enough money to get him housed as he awaits chemotherapy which is a very difficult thing to do for us. We could really use some help in doing so. Money is limited for us as we, too are just surviving. 

Please help. We would be so grateful. Cancer is a mean disease.
