Meningioma

Brain tumors result from abnormal cell growth in or around the brain, categorized as malignant (cancerous) or benign (non-cancerous). Malignant tumors spread rapidly, while benign ones grow slowly and are generally non-fatal. They can affect brain function if they become large. Tumors may arise in various brain areas, including the pituitary and pineal glands, and brain membranes. Primary tumors develop in the brain, while metastatic tumors spread to other body parts, often through the bloodstream. Some tumors may also form on the spinal cord. Meningiomas are slow-growing, non-cancerous brain tumors that develop on the meninges, the protective layers covering the brain and spinal cord. They primarily affect women and the elderly and can lead to serious disability if left undiagnosed. Though the causes remain unknown, genetic factors and chromosomal changes may play a role. While most meningiomas are non-cancerous, some can be malignant and spread to nearby tissues or other parts of the body. Symptoms vary depending on the tumor's location and commonly include neurological issues such as blurry vision, severe morning headaches, hearing problems, memory loss, and muscle weakness.
