人体正常代谢及病理条件下均可产生氧自由基。越来越多的研究显示氧自由基参与了癌症的发生、发展及转归等各个过程。更新的研究表明，氧自由基可以促使人类的大敌——癌症得以逆转，即癌细胞再分化为正常或接近正常的细胞。这为人类征服癌症提供了全新的观念和思路。 Oxygen free radicals can be produced under normal metabolic and pathological conditions in the human body. More and more research shows that oxygen free radicals are involved in various processes such as the occurrence, development, and prognosis of cancer. Newer research shows that oxygen free radicals can promote the reversal of cancer, the great enemy of humans, in that cancer cells re-differentiate into normal or near-normal cells. This provides new ideas and ideas for humans to conquer cancer.
