B17, if you know please reply

I have read that taking Vitamin B17 can have a good effect on fighting cancer. How safe is it to take it as a supplement in a diet and how to take it (can I get it without prescription?).

My mother has breast cancer and we found out recently about a possible positive effect of B17 vitamin.

Ivy,  My wife has been taking Vit 17 3 times a day.  She has stage 4 kidney cancer.  Nothing has stopped it but we continue on bc there are no side affects.  Got a recent article about how asparagus has helped and news about omega the DHA kind is better that helps.  I hope this answer your question and that you look up the other.  Stay strong it's a long joruney and your mom will need you.
