Schwannomas are benign tumors that develop from Schwann cells, which are responsible for producing the myelin sheath that insulates nerves. These tumors can occur in various parts of the body, including the spinal cord, peripheral nerves, and cranial nerves. While they are generally non-cancerous, they can cause symptoms depending on their size and location, such as pain, numbness, or weakness. Most schwannomas grow slowly and may not require treatment unless they cause significant symptoms. In such cases, surgical removal is often the preferred option. Regular monitoring may be recommended for asymptomatic schwannomas to ensure they do not grow or lead to complications.
