Graviola and cancer
Overall, there is no evidence to show that graviola works as a cure for cancer. In laboratory studies, graviola extracts can kill some types of liver and breast cancer cells that are resistant to particular chemotherapy drugs. But there haven’t been any studies in humans. So we don't know whether it can work as a cancer treatment or not.

Many sites on the internet advertise and promote graviola capsules as a cancer cure but none of them are supported by any reputable scientific cancer organisations.

We do not support the use of graviola to treat cancer. Our advice is to be very cautious about believing information or paying for any type of alternative cancer therapy on the internet.
