Compounds in noni supplements may have significant anti-cancer properties, according to research summarized by experts at the Memorial Sloan-Kettering Cancer Center, who suggest that noni might slow growth of cancerous tumors. For example, a laboratory study published in 2013 in the "Asian Pacific Journal of Cancer Prevention" found that noni extract was nearly as effective as a chemotherapy in killing cultured cervical cancer cells. The authors concluded that noni induces cancer cells to die through an irreversible process called apoptosis. Other laboratory studies summarized by the cancer center experts support noni's ability to prevent or slow growth of cancer cells, but this possible benefit still needs confirmation in clinical trials with human subjects.
