It effectively targets and destroys malignant cells in almost 12 types of cancer such as breast, lung, pancreas, prostate and colon
The commonly used drug that helps combat cancer, as a part of chemotherapy is Adriamycin. The Annona muricata tree contains compounds that have 10,000 times more strength to combat cancer than Adriamycin.
