Brain cancer, also known as malignant tumor of the brain. The most important symptoms in the early stage are usually headache, nausea, vomiting and other symptoms of increased intracranial pressure. The headache is usually stronger in the morning when you get up. Other diseases, such as benign brain lesions or cervical spondylosis, may also cause symptoms of nausea and vomiting, which need to be differentiated from brain malignant tumor. Depending on the location, brain cancer may cause some functions, as well as neurological and speech disorders, such as causing visual impairment on one side, hemiplegia or hearing impairment on one side, speech dysfunction, etc. Such cases need early detection and treatment. Generally, brain cancer can be treated by surgery or gamma knife, which can control the development of the disease.
