Papaya’s contents have potentially perspective anti-tumor features and can fight various cancer diseases including cervix of the uterus, mammary gland, liver, lungs and pancreas cancers.

The Tokyo (Japan) university oncologists as well as their Florida (USA) colleagues have first ascertained that extract of the dried papaya tree leaves stimulates release of important signal molecules called Th1 type cytokines. Besides papaya extract has no toxic effect onto the normal cells.

Within the lab test the scientists subjected 10 various types of cancer tumors cells to the impact of the four papaya leaves and analyzed the effect 24 hour later. Scientists also monitored the effect of the papaya onto the anti-tumor molecules release. And it turned to be that the components from the fruit tree leaves contributes to the Th1 type cytokines release that are quite important for the immunity regulation.
