AHCC® & Cancer


One of our primary goals is to make sure you fully understand every aspect of AHCC®. We want you to understand how AHCC® is researched, the clinical trials undertaken, and the results of all studies about AHCC® and immune system health. On this page we provide an overview of the key research done into AHCC® and a range of conditions and lifestyle factors.


AHCC® has been used with great success in cancer patients. Data from the treatment of over 100,000 individuals with various types of cancer have shown AHCC® treatment to be of benefit in 60% of cases. (Kenner p. 15) AHCC® is particularly effective for liver, lung, stomach, colon, breast, thyroid, ovarian, testicular, tongue, kidney and pancreatic cancers. (Kenner p. 15)

One landmark AHCC® trial enrolled 269 patients with liver cancer. Following surgery, about half of the patients took AHCC® and about half did not. The results were dramatic: At the end of the ten-year study, only 34.5% of the AHCC® patients experienced a recurrence in their cancer, compared with 66.1% of the control group. Similarly, while 46.8% of the patients in the control group had died at the end of ten years, less than half that amount — 20.4% — of those in the AHCC® group had.

Another study found that AHCC® not only prolonged survival of advanced liver cancer patients, it also improved various parameters of quality of life, including mental stability, general physical health status and the ability to have normal activities.
