In Peru, Lucy met some sort of a shaman. He wrote down her a list of things she must eat and things to avoid. This list also contained some herb, that she had to eat during the 2-3 months she was there.
After a few months, she got back home. 6 months after - no cancer. Year after this all happened she was dancing at my sister's wedding, healthy and happy.
Now as for the Peru guy and the friend of my friend who been there :) He had a brother. They both got cancer. One of the brothers decided to go with traditional treatment (radiation and all that). The other one went to Peru.
Long story short: the one who picked traditional methods died many years ago. The other one (who convinced Lucy to go) - completely recovered.
As far as I know, overall treatment was less than $5,000. If I'm not wrong, this was including rent + air flight.
I must add, that Lucy lost 45 pounds within a year. During my sister's wedding, she was only eating some oceanic fish and rice.
Edit:
This is just a short story from people I know in person. All of them are scientists working at university, doing researches on molecular genetics & microbiology.
I'm not even sure the guy in Peru was a shaman. That's just how I called him here. I just don't believe he was a real doctor. The gist of the whole treatment was fasting, not a herb.
