A brain tumor is an abnormal growth of cells in the brain or central spinal canal. These tumors can be classified as either benign (non-cancerous) or malignant (cancerous), and they can originate from the brain tissue itself (primary brain tumors) or spread to the brain from other parts of the body (secondary or metastatic brain tumors). Symptoms may vary widely depending on the tumor's location, size, and type, but common indicators include headaches, seizures, cognitive or behavioral changes, and motor skill deficiencies. Diagnosing a brain tumor typically involves imaging tests such as MRI or CT scans, followed by a biopsy to determine the type of tumor.
Treatment for brain tumors depends on several factors, including the tumor type, size, and location, as well as the patient's overall health. Common treatment options include surgery to remove the tumor, radiation therapy, and chemotherapy. While advancements in medical technology have improved treatment outcomes significantly—enabling more precise targeting of tumors and minimizing damage to surrounding healthy brain tissue—challenges still exist. It's crucial for patients to discuss all available options with their healthcare providers to determine the best course of action tailored to their specific situation.
