What percentage of people with myasthenia gravis patients have thymoma?

ANSWER

About 15% of all myasthenia gravis patients are found to have a thymoma, a tumor of the thymus. Although most thymomas are benign (not cancerous), doctors usually remove the thymus (the procedure is a thymectomy) to prevent the potential spread of cancer. In fact, thymectomy seems to improve symptoms of myasthenia gravis in some people, even if they don't have a tumor.
