The papaya fruit is good for your health.
But the leaves of the fruit's tree may one day save your life.
Researchers are studying the leaves, and using the extract in papaya tea.
Early findings show that if you feed the cancer cells the tea extracts, it kills the cancer cells and seems to give the immune system extra ammo to fight cancer.
Doctor Nam Dang says the tea extract works on a number of different types of cancer.
He hopes to start human clinical trials in the next few years.
