A cervical polyp is a benign tumor that is found on the surface of the cervical canal. They can cause irregular menstrual bleeding, but more often they show no symptoms. The cause of this type of cancer is not fully understood by the experts. It may result from an infection or from a long term or chronic inflammation, an abnormal response to an increase in the estrogen levels, and in the congestion of blood vessels in the cervical canal.
The diagnosis of cervical polyps is relatively easy, since they can be easily seen by a physician. They appear to be smooth stalks with a red or purple color and they protrude from the cervical canal.
