The harm of brain cancer should be taken seriously

In recent years, there are many people suffering from brain tumors. When thinking of brain tumors, most readers will be a little scared. Brain tumors are indeed a terrible disease, which poses a great threat to the lives of patients. Therefore, the harm of brain cancer should be taken seriously. The following is a detailed introduction for everyone:

1. Blindness. Not many people go blind suddenly due to brain tumors. Often, vision loss occurs first. If it is not treated promptly and effectively, it will gradually develop into blindness. Some children, and even a few people, ignore the loss of vision on one side, and only find out that one eye is blind during examination. Some patients, especially the elderly, have eye diseases accompanied by brain tumors. When vision changes, they mistakenly think it is an eye disease, delay treatment, and develop blindness. Common tumors include craniopharyngioma, pituitary adenoma, meningioma, glioma, and high intracranial pressure caused by brain tumors.
2. Paralysis is mostly hemiplegia. The incidence is high when the tumor is located near the motor area of ​​the brain, the basal ganglia, and the ventral side of the brainstem. It starts with mild paralysis, gradually develops into severe paralysis and then complete paralysis. While there is hemiplegia, there will be other manifestations, such as symptoms of high intracranial pressure. If it is treated in time in the early stage of the disease, it will generally not develop into hemiplegia. A small number of tumors are accompanied by bleeding and sudden hemiplegia, and the manifestations are similar to cerebral hemorrhage. Head CT or magnetic resonance imaging should be performed in time for early diagnosis and early treatment. It is common in meningioma and glioma.
3. Sudden death is mostly caused by increased intracranial pressure caused by the tumor, brain herniation, compression of the respiratory and circulatory centers, and respiratory and cardiac arrest. It is more likely to occur when the tumor has grown to a large size and is close to the late stage and has not received timely and effective treatment. However, some tumors are not large, but are located in the midline and affect the cerebrospinal fluid circulation in the early stage. If the cause is not eliminated, it will also cause brain herniation and sudden death. It is more common in gliomas and brain metastases.
