Researchers tested a fungus called Ganoderma weberianum-sichuanese from Ghana’s Lower Volta River to see if it could kill cancer cells. They found that extracts from this fungus could effectively suppress the growth of three types of human cancer cells—prostate cancer, T-cell leukemia, and a rare dendritic cell leukemia—without harming normal liver cells. The most promising components were found in certain fractions of the extract, suggesting this natural fungus could potentially be developed into new cancer treatments.
