I would have to say that when it comes to all types of cancer; if you find it on the internet or your oncologist doesn't present it to you as a treatment adjunct or alternative it probably has little to no merit and as Brian stated will only separate you from your hard earned dollars and leave a whole lot of disappointment.
If ever anyone is in doubt about a possible treatment they should discuss it with their doctors.
As for the green tea and prayers they are all part of a healthy lifestyle and will certainly not harm you and studies have shown that prayer, meditation and humor all reduce stress and strengthen the immune system.
Cheers,
