Screening tests check for signs of cancer in people who don't have any symptoms. Unfortunately, no screening or blood tests exist that can detect a brain tumor early. The tumor is usually found after symptoms appear. Because brain tumors are rare, screening the majority of the population is neither possible nor justifiable. If you ever experience new symptoms, such as headaches or weakness, see a doctor.
