Brain tumor and brain hemorrhage are two completely different diseases. In the former, tumors growing in the skull are commonly referred to as brain tumors, including primary brain tumors that occur in the brain parenchyma and secondary brain tumors that metastasize to the skull from other parts of the body. Primary brain tumors are divided into benign and malignant according to their biological characteristics. Benign brain tumors are slow-growing, with intact envelope, no infiltration of surrounding tissues, and good differentiation; malignant brain tumors are fast-growing, without envelope, with inconspicuous boundaries, infiltrative growth, and poor differentiation. Regardless of benign or malignant, they can squeeze and push normal brain tissues, causing an increase in intracranial pressure and threatening human life. The latter, cerebral hemorrhage, also known as cerebral hemorrhage, is the most serious of acute cerebrovascular diseases, and is currently one of the most lethal diseases in middle-aged and elderly people. Middle-aged and elderly people are the main population of cerebral hemorrhage, with 40-70 years old being the most important age of onset. The causes of cerebral hemorrhage are mainly related to cerebral vascular lesions and sclerosis. The causes of cerebral hemorrhage are mainly related to lesions and sclerosis of cerebral blood vessels. Lesions of blood vessels are closely related to hyperlipidemia, diabetes, hypertension, aging of blood vessels and smoking. The brain hemorrhage (cerebral hemorrhage) is usually referred to as spontaneous primary brain hemorrhage. Patients often have a sudden onset due to emotional excitement and strenuous exertion, manifesting as aphasia, hemiparesis, or in severe cases, unconsciousness, and more than half of the patients are accompanied by headache and vomiting. Cerebral hemorrhage (cerebral hemorrhage) refers to non-traumatic bleeding in the brain parenchyma. Most of them are caused by the rupture of small cerebral artery lesions associated with hypertensive disease when the blood pressure rises suddenly, called hypertensive cerebral hemorrhage. The former is mainly surgical, while the latter can be surgical or non-surgical depending on the bleeding site and the amount of bleeding Both can be complicated by: epilepsy, fever, etc.
