Brain cancer is a common name, often referring to intracranial malignant tumors, the most common being glioma. The treatment for patients with advanced stage is limited, generally based on chemotherapy, supplemented by immunotherapy, targeted therapy and Chinese herbal medicine or acupuncture and massage treatment. As treatment progresses, the side effects of chemotherapy intensify accordingly, often causing impaired digestive function and suppression of bone marrow hematopoietic function, making it impossible for patients to persevere. Therefore, while undergoing chemotherapy, it is necessary to eat more easily digestible and nutritious food, pay more attention to rest, and not to overexert oneself in order to help chemotherapy proceed smoothly. Regular cranio-cerebral and spinal-cord imaging review is needed to understand the progress of the disease and the effect of treatment.
