A cone biopsy is a quick outpatient surgery used to find and treat a problem in the cervix. Your healthcare provider may do a cone biopsy if 1 or more Pap tests and a colposcopy (microscope) exam showed abnormal cells on your cervix. A cone biopsy takes less than an hour. You’ll be able to go home the same day. The most common type of cone biopsy is the loop electrosurgical excision procedure (LEEP). A wire with electric current is used to take the biopsy.
|A cone-shaped piece of tissue is cut from the cervix. This removes the abnormal cells. The tissue that grows back is usually normal.
Preparing for a cone biopsy
Follow any directions you are given for not eating or drinking before surgery. You’ll also need to have an adult friend or family member drive you home after the procedure. On the day of surgery, be sure to arrive at the hospital, surgery center, or healthcare providers office in time to sign in and get ready for your procedure.
Here is what to expect during surgery:
You’ll be given anesthesia before your biopsy to keep you comfortable during surgery.
Your healthcare provider then puts a thin metal tool (speculum) into your vagina to spread it open. This allows your health care provider to see your cervix.
Then a cone-shaped piece of tissue is removed from the cervix. The tissue is cut from the opening up into the canal. This may be done with a small knife or with a laser or with the LEEP wire.
A special cream may be put on your cervix to control bleeding.
The tissue that is removed is then sent to the lab. The lab studies the tissue and makes sure the abnormal cells have been cut away. New tissue grows back in the cervix in 4 to 6 weeks.
Recovery from a cone biopsy
After the procedure, you may have:
Don’t use tampons, don’t douche, and don’t have sex until your healthcare provider says it's OK.
When to call your healthcare provider
Call your healthcare provider if you have:
Heavy bleeding, or bleeding with clots
Fever over 100.4°F (38°C) or higher, or as directed by your provider
Bad-smelling vaginal discharge
Your healthcare provider will discuss the risks and possible complications of cone biopsy with you. These include:
