Currently, over 100 strains of the HPV virus have been identified. However, only about 40 of those 100 strains are considered “high risk.” It is these high-risk strains that can cause low-grade cervical cell abnormalities, high-grade cervical cell abnormalities that are precursors to cancer, and anogenital cancers.
Within those 40 “high risk” strains two specific strains—HPV-16 and HPV-18—account for about 70% of cervical cancers. It was those two strains tested in the study that showed that AHCC could potentially be a natural treatment to HPV. However, additional studies would need to be conducted to confirm.
