We report here five cancer cases, consisting of follicular lymphoma, colon cancer, ovarian cancer, and two cases of lung cancer, in which the patients were concerned about the side effects of chemotherapy and opted instead to use APCO innovation, Fortified Mangosteen Extract (FME), a plant-based stem cell immunotherapy. The treatment was administered over a 12-week period, with clinical follow-up and assessment of treatment outcomes. Across these cases, the patients became cancer-free without observed side effects. All patients also reported an improved quality of life compared with the period before their cancer diagnosis. In three patients, telomere length was found to have increased, indicating biological age reversal.
