Brain cancer, also known as brain tumor, refers to the abnormal growth or multiplication of cells in the brain, causing the formation of a mass or tumor. These tumors can originate within the brain (primary brain tumors) or spread to the brain from other parts of the body (secondary brain tumors, also known as metastatic brain tumors). Primary brain tumors can be further classified as either benign (non-cancerous) or malignant (cancerous).
Malignant brain tumors exhibit uncontrolled cell growth and have the potential to invade nearby healthy tissues, leading to various health complications. They can originate from different types of brain cells, such as glial cells, which support and protect brain cells, or neurons, the cells responsible for transmitting signals within the brain.
Brain cancer symptoms can vary widely depending on the tumor size, location, and rate of growth. Common symptoms include persistent headaches, seizures, difficulty with balance or coordination, changes in personality or behavior, impaired cognition, vision or hearing problems, and weakness or numbness in the extremities.
Treatment options for brain cancer depend on several factors including the tumor type, location, size, and individual patient characteristics. They may include surgical removal of the tumor, radiation therapy, chemotherapy, or a combination of these approaches. Additionally, targeted therapies and immunotherapies have also shown promise in certain cases. Early detection and treatment are crucial for improving outcomes and the quality of life for individuals affected by brain cancer.
