Help Dustin fight metastatic colon cancer

My name is Sally Pyle, and I'm asking for help for my son Dustin Penwright.  He is fighting stage 4 metastatic colon cancer at the early age of 40.  He is not financially prepared for something as devastating as this.  His hospital bills are already approaching the $100K mark and he has one medication that costs $700. out of pocket every 30 days on top of many other meds.   He also has some quickly approaching custody hearings that may require legal counsel which he can not afford during treatment.
If you can help in any way, we would be forever grateful.  He is really trying his best to keep his spirits up with all the bad news.   His cancer has already spread to his liver and now his kidney.   
All funds will go towards prescriptions and his hospital bills and care.
