Final answer:
Brain tumors fall into primary and metastatic categories, with varied symptoms based on the affected brain region. Diagnosis often involves MRI or CT scans and treatment can range from surgery to chemotherapy, emphasizing the importance of early detection.
Step-by-step explanation:
Brain tumors are abnormal growths of cells in the brain and can be classified into two major types: primary brain tumors which originate in the brain, and metastatic brain tumors which have spread from cancers located in other parts of the body. Common examples of primary brain tumors include gliomas, meningiomas, pituitary adenomas, and schwannomas. Metastatic brain tumors are more common than primary brain tumors. Symptoms of brain tumors can vary widely and may include headaches, seizures, cognitive or personality changes, balance and coordination issues, and vision or speech problems.
Diagnosing a brain tumor often involves imaging techniques such as MRI or CT scans, and sometimes a biopsy is performed to determine the type of tumor. Treatment options for brain tumors may encompass surgery, radiation therapy, chemotherapy, targeted therapy, or a combination thereof. The specific treatment plan depends on the type, location, and size of the tumor as well as the patient's overall health. Early detection and diagnosis are crucial for effective treatment. The central nervous system comprises two components: the brain and the spinal cord. The brain's major areas include the cerebral lobes, cerebellum, and brainstem, each responsible for various vital functions. The spinal cord primarily transmits information between the brain and the body.
