In the whole andes, there is a claim that chirimoya cures cancer.
This claim is supported long across the andes community, and in dubious sites like this one.
My question is: What is the actual extent -currently known- to the healing power of the chirimoya fruit? Has that fruit a proven* success against cancer in any way? (at least helping in any way with the healing of at least one form of cancer).
(*) This should not need clarification but since this is my first question here I state: at least one study from a reputable laboratory proving some kind of success regarding any form of cancer
