Extracts of a fruit grown on tropical vines appears to have breast cancer blocking powers, say researchers.
Scientists found key ingredients of the green and knobbly bitter melon fruit interfered with chemical pathways involved in cancer growth. It turned off signals telling the breast cancer cells to divide and switched on signals encouraging them to commit suicide. Experts told Cancer Research journal more trials were needed.
Although promising as an anti-cancer agent, trials in animals and then humans are still needed, study co-author Dr Rajesh Agarwal from the University of Colorado, US, said. And there is no proof that eating lots of bitter melon would offer any cancer protection, he said.
