They found that mice fed the substance had 68% – 98% fewer cancer cells. Generally speaking, the occurrence of cancer can be roughly divided into three stages: first, the DNA of normal cells is damaged and the genetic factors of cancer are awakened; Second, cell division is accelerated and carcinogenesis is involved; Third, the tumor worsened and began to metastasize.
