Hi Darrian
The U.S have made booklet and information available specific for cancer survivors on how to manage their finances, the physical, emotional and mental effect of surviving cancer. The American Cancer society have a website on nutrition (what to eat) and physical activities cancer survivors can engage in. They also offer grants and taxes free to cancer foundation who helps cancer survivors.
