Chemo treatments for our dad

Our dad has diagnosed with Colon cancer last year, had surgery and underwent chemo to kill the cancer. roughly 2 weeks ago he was told the cancer is back but this time has spread and he now requires 12 more chemo treatments which are rather exspensive. He needs $800 up front just to get his first treatment going.  Hes only 59 and has 4 kids, a wife and several grandkids he would like to be around for. Anything would help! Whether it be sharing, donating or whatever! Thanks!
