Malignant tumors, that is, cancers,

Malignant tumors, that is, cancers, are cancerous changes that occur in normal cells of the human body under the action of various carcinogenic factors, which turn normal cells into malignant cancer cells. They are a type of serious threat to human health. At present, synthetic anti-tumor and antioxidant drugs have certain limitations in the treatment. The development of natural anti-oxidant and anti-tumor drugs has attracted more and more attention from medical workers and scientific researchers. Fungi contain fungal polysaccharides, which can activate macrophages, T, B lymphocytes, and complement systems. By enhancing the host's immune regulatory system, they can achieve anti-oxidant and anti-tumor functions. The fungal polysaccharides that have been researched in depth include lentinan, ganoderma, white fungus, enoki mushroom, Hericium erinaceus, pine mushroom and Pleurotus eryngii polysaccharides.
