I thought you said men in other countries, especially the Far East, have less cancer. Well I did. They have less clinical cancer, but not less latent cancer. Remember, latent cancer is in a quiescent stage that poses no harm. Let's take China as an example.
Chinese men have the same percentage of latent cancer as American men.
In China, the answer is extremely few. Clinical rates in China are the lowest in the world at 2.8 per 100,000 people a year. American whites have 100 per 100,000. That's thirty-six times higher than rates in China. In a word, diet.
