A brain tumor refers to an abnormal growth of cells within the brain or its surrounding structures. These tumors can be either benign (non-cancerous) or malignant (cancerous), and they arise from the uncontrolled division and multiplication of cells in the brain. The exact cause of brain tumors is often unknown, but certain risk factors such as genetic predisposition, exposure to radiation, and certain inherited syndromes may increase the likelihood of their development.
Brain tumors can vary in size, location, and aggressiveness, leading to a wide range of symptoms including headaches, seizures, cognitive difficulties, changes in behavior, and neurological impairments. The diagnosis and treatment of brain tumors involve a comprehensive evaluation, which may include imaging tests, biopsies, and a multidisciplinary approach involving neurosurgeons, oncologists, radiation therapists, and other healthcare professionals. Treatment options for brain tumors include:
- radiation therapy
- targeted drug therapies
- supportive care
