financial assistance for a Vietnam Vet

I have been trying to figure out a way to help my parents out while being so far away and decided on this! My father was diagnosed in November with throat and liver cancer. He has to travel 1 to 1 1/2 hours fivr days a week for radiation and chemotherapy. During this time he is limited to how much he can work. It is very expensive between gas and healthy food. My mother is his care giver so she is unable to work as well. They are wonderful people who could use any help they can get right now. My father is also a Vietnam Veteran and they have been through many hardships together! Any donations would be greatly appreciated and more importantly, positive thoughts and prayers for his health! Thank you for your time!
