What is cone biopsy?
A cone biopsy, also known as a cervical conization, is a small diagnostic procedure, performed under general anesthesia, that removes a cone-shaped section of abnormal tissue from the cervix.
A cone biopsy is used to detect cervical cancer or precancerous cells. It is also a treatment option to remove all abnormal cells (precancerous cells).
What is conization?
General anesthesia is used. The surgery begins with the placement of a speculum into the vagina so that the cervix can be seen. A small cone-shaped section of tissue is then removed from the cervix, either with a scalpel, a heated wire loop or a laser.
The procedure takes about 15 minutes. The removed tissue is then sent to the laboratory to make sure all abnormal cells have been removed or to check for the presence of cancer. To stop any bleeding, gauze may be placed in the vagina. While in place, a catheter may be inserted.
Conization makes it possible to diagnose
and treat cervical cancer.
Why is a cone biopsy or conization performed?
A biopsy may be recommended if you are experiencing symptoms associated with cervical cancer. It is also possible to do a cone biopsy to treat abnormal cervical cells, which are detected through a screening test on the cervix. Abnormal precancerous cells, if left untreated, can develop into cervical cancer.
Preparing for conization
Because this procedure is performed under general anesthesia, food intake should be avoided 6 to 8 hours before and drinking should be stopped 2 hours before surgery.
What does a cone biopsy feel like afterwards?
After a cone biopsy, it is possible to have some cramping during the week. For 2 to 3 weeks after the procedure, the discharge may be bloody, heavy and yellow in color.
It is important to refrain from using tampons and not having sexual intercourse for 4 to 6 weeks after surgery.
What do abnormal conization results mean?
A normal cone biopsy result would mean that there are no cancerous or precancerous cells in the cervix. An abnormal result would mean that there are cancerous or precancerous cells in the cervix. If cancer is detected, then further testing will be done and a treatment plan will be put in place. All this will be assessed by a specialist.
