Vegan a cure for Cancer?

Saw this sticker posted.  While one may be able to reduce their risk of certain types of cancer, a vegan diet by no means will cure cancer.  A good diet (whether vegan or not) is obviously important to keep a healthy immune system and to keep one's strength and energy up as they are going through proper medical treatments.  This type of advice can be very dangerous as it can cause some people to negate medical treatment.  Raw diets are not necessarily healthier.   Many plant food items are better digested (and thus more nutrients absorbed) after being cooked.
