The cervix, or opening of the womb, usually has a smooth surface. However, harmless growths, called polyps and cysts, can occur in some women. These can cause changes to the surface of the cervix.
Polyps are small lumps thought to be caused by an irritation to the cervix.
They grow from the tube part of the cervix. Bleeding with sex or between periods are the only signs that these polyps are present. You would not be able to feel these during sex or self exam. If you have these signs and polyps are found by your healthcare provider, they are easily removed. They may return in the future but are usually harmless in young women.
