Hey PrincessBee.....it's sad to hear about your friend but it's fortunate that she's caught it in the earlier stages to begin doing something about it sooner.
I'm sure you've been searching online too but came across these websites.....

I've read/heard stories on people curing cancer/sickness with raw diets. I worked with a lady who had a brain tumour. She was so frightened and sick of chemo (literally) that she changed her diet (lots of carrot juice she turned yellow) and went and saw a spiritual advisor who saw her through this time.
There are also health retreats that specialise in treatments. I remember reading an article in Healthy Options about a family who took their daugther to the uk for natural treatment and the medical board took them to court because they were "endangering their daughters life" etc.
There is also a man who lives up on the Sunshine Coast who had 6 months to live (found out he was dying from Asbestos) and turned to a raw diet and excercise and is now fighting fit.......that was many years ago.
These are only a couple of examples off the top of my head but there are more out there. One thing too is that sickness can be caused by both diet and emotional reasons so perhaps is a good idea to look into Louise Hays book.
On Sunday night there was a doco on children with cancer being treated by chemo. It just showed the horrors of what it does to your body and must be a difficult decision for anyone to make......
I wish your friend all the best and believe she can cure herself!!!!!!!!!!
Lou
