Most cervical polyps are benign (noncancerous). However a small percentage of polyps are abnormal and if left untreated, these may develop into cancer. It is not possible to tell which polyps may turn cancerous, so it is best to have them removed and they can then be sent away for tests.
If a cervical polyp isn’t removed, it may continue to grow. Depending on its location and size, a cervical polyp may affect your fertility. Polyps may also become inflamed and infected, resulting in an unpleasant, yellow, vaginal discharge.
