Ganoderma mushroom for Cancer Treatment. Reishi mushroom, scientifically known as Ganoderma lucidum or Ganoderma sinense, has been commonly known as the mushroom of longevity or immortality. Out of all of the different types of mushrooms, reishi mushrooms seem to be the most widely used mushrooms for cancer prevention and to inhibit tumor growth.  Reishi has been used medicinally in East Asia since ancient times. It is a traditional medicine used throughout Asia for cancer prevention. The study found that the polysaccharides in  reishi mushrooms  may help  cancer -fighting immune cells, called lymphocytes, stay active. Thus, Ganoderma lucidum clearly demonstrates anticancer activity in experiments with cancer cells and has possible therapeutic potential as a dietary supplement for an alternative therapy for breast and prostate cancer. Biobritte supplies Ganoderma mushrooms in different product forms such as Ganoderma Capsules, Ganoderma Powder, Ganoderma extract, and dry Ganoderma mush
