Even though there is not enough medical evidence, and there have not been any large scale studies on humans, soursop has been widely promoted as an alternative cancer treatment. According to the Memorial Sloan-Kettering Cancer Center, soursop or graviola extract proved to be effective against breast cancers cells. In laboratory studies, soursop extracts have been known to kill some types of liver and breast cancer cells that are resistant to particular chemotherapy drugs. A study also showed that graviola may inhibit tumororigenicity and metasis of pancreatic cancer cells.
A series of experiments conducted by the Purdue University College of Pharmacy, shows the anti-cancer potential of soursop. It was found that the acetogenins present in the fruit successfully inhibited malignant cells that could turn cancerous. Research also indicates that soursop is effective against multi-drug resistant (MDR) cells that are born in the process of cancer. Consuming the fruit helped people cope with the side effects of chemotherapy. It has been established that the leaves more than the fruit of the soursop plant is full of cancer preventing chemicals.

It only affected cancer cells membranes and not those of healthy cells. She also reports that researchers in Taiwan, found that 'the main graviola acetogenin, annonacin was highly toxic to ovarian, cervical, breast, bladder and skin cancer cell lines at very low dosages'.
Soursop or graviola has become known because of its cytotoxic properties (ability to kill cells). It is believed that given the role of the immune system in eliminating dysfunctional cells, one can conclude that soursop can support the functions of the immune system in an exceptional manner. According to canceractive.com 'research has indicated, albeit in vitro, that several of the active ingredients (Annonaceous acetogenins) kill malignant cells of 12 different types of cancer including breast, ovarian, colon, prostate, liver, lung, pancreatic and lymphoma.'
