These tumours typically grow on peripheral nerves, the nerves that extend outside the brain and spinal cord.
Schwannomas are usually slow-growing and non-cancerous. They are encapsulated, meaning they are surrounded by a fibrous capsule, and can occur in various parts of the body, including the head, neck, extremities and along the spinal nerves.
Symptoms vary depending on the location and size of the tumour, and may include pain, tingling, numbness, weakness or a palpable mass in the affected area. In many cases, schwannomas are discovered incidentally during imaging performed for other reasons. Treatment often involves surgical removal, especially if the tumour is causing symptoms or affecting nerve function. In some cases, observation with regular monitoring may be recommended if the tumour is small and not causing significant issues. Radiation therapy or other treatments may be considered in certain situations.
