Brain tumours are abnormal cell growths in the brain that can be classified as malignant (cancerous) or benign (non-cancerous). They could originate in the brain and spread to other areas of the body. The size, location, and rate of growth of brain tumours can affect their symptoms, but frequent ones include headaches, seizures, changes in personality or behaviour, and issues with vision or hearing. For better results, early diagnosis and treatment—which could include chemotherapy, radiation therapy, and surgery—are essential.
Although the precise aetiology of brain tumours is frequently unknown, genetics, radiation exposure, and specific environmental variables are thought to be involved. Research is being done to create more potent treatments and to have a better understanding of the mechanisms behind the development of brain tumours. The diagnosis and treatment of brain tumours have been greatly enhanced by developments in imaging technology and surgical methods, improving patient outcomes for a large number of patients.
