Ganoderma lucidum spore powder is a health product made of Ganoderma lucidum through wall-breaking processing. Clinical research has found that this health product has certain effects of enhancing body immunity and inhibiting the growth of cancer cells, etc. Therefore, lung cancer patients can consume Ganoderma lucidum spore powder, which may be beneficial to the control of the disease. However, lung cancer patients cannot take ganoderma lucidum spore powder as the main treatment because its role as a healthcare product is limited in the treatment of the disease.
