Mushrooms contain natural compounds that show promise in fighting cancer by triggering cancer cell death and boosting immune function. Different mushroom species like oyster, shiitake, and button mushrooms contain substances such as beta-glucans and other polysaccharides that have demonstrated anticancer properties in laboratory and animal studies. While these mushroom compounds work through multiple mechanisms including preventing new blood vessel formation to tumors and stopping cancer cell division, more human clinical trials are needed to confirm their effectiveness as cancer treatments.
