1, anti-cancer drugs, life is varied. In modern times, "acupuncture" was particularly prominent. But any "cancer prevention" is just empty talk, and the basic real prevention ability is limited, which can basically be regarded as invalid.

In addition, we should know that as far as human science is concerned, we don't even know the chemical mechanism and combination of cancer, and the appearance, shape and shape of cancer. I don't even know "opponent and enemy". Do you want to talk about defense? Isn't that limited talk?
At present, as far as human science is concerned, as long as you live a correct and healthy life, that is the best cancer defense!
