I don't understand this. You say there are few people who completely cure the cancer using natural ointments and medicines and that their success results are over 90%.
So are you saying that the nature medicines are working or not?
There is no 100% cure for all types of cancer but there are plenty of natural ways of fighting it, eg THC from cannabis is well known for its anti-cancer properties (it forces cancer cells to go into cellular apoptsis). The spanish study on rats cured something like half of all brain tumours, similar studies have shown the same.
Best to look at them as preventative measures rather than an outright cure, plenty of organic foods like garlic, brocolli, spices (turmeric etc) have anti-cancer properties so if you eat healthily, drink clean water, exercise, don't smoke or drink too much, more than likely you wont get cancer in the first place.
