I actually think that if you find it soon enough, you should try natural methods first. There has been a lot of success with them in the past decade.
But it is usually found too late and radiation is possibly the best route.
Steve Jobs died because he believed in the "natural method" over real therapy that very well might have saved him. There's a reason most of that stuff is called "natural" and aren't approved drugs.
There are so thousands of different types of cancer. Radiation does not work on all of them. There are also many types of drugs for cancer, and they depend on which type of cancer you have.
If you've got cancer in the early stages, going the natural route can be the stupidest decision you'd ever make. Be safe, and see real doctors.
