Because cone biopsies carry risks such as bleeding and problems with subsequent pregnancies, they have been replaced with newer technologies except in a few circumstances.
About one in 10 women experience bleeding from the vagina about two weeks after the biopsy. There is also a slight risk of infection or perforation of the uterus. In a few women, the cervical canal becomes narrowed or completely blocked, which can later interfere with the movement of sperm. This can impair a woman's fertility.
If too much muscle tissue has been removed, the procedure can lead to an incompetent cervix, which can be a problem with subsequent pregnancies. An incompetent cervix cannot seal properly to maintain a pregnancy. If untreated, the condition increases the odds of miscarriage or premature labor.
Cervical conization also may temporarily alter cervical cells, which can make a Pap smear test hard to interpret accurately for three or four months.
