A cone biopsy (conization) is a type of surgery. It removes a cone-shaped piece of tissue from the cervix. The cervix is the lower part of your uterus. It opens into your vagina.
There are a few ways the doctor can remove the tissue. One way is to use a surgical knife called a scalpel. Another way is to use a thin wire loop that's charged with electricity. Or the doctor can use a laser.
You may be asleep during the surgery. But it is usually done while you are awake. Either way, you will not feel pain. The doctor removes the tissue through the vagina. The surgery won't leave a scar on the outside of your body.
After surgery, another doctor will look at the tissue under a microscope. The doctor will check it for abnormal cells.
As long as you are stable, you can go home after a period of observation. You will probably be able to return to your normal routine in 1 or 2 days. But be sure to wait to have sex until your doctor says it's okay.
Most people can return to their normal activity level after 1 to 2 days.
After several Pap test results are normal, you and your doctor can decide how often to schedule future Pap tests.
Some vaginal bleeding is normal for up to 1 week. Some vaginal spotting or discharge (blood or dark brown) may occur for about 3 weeks.
A cone biopsy may be done after a cervical cancer screening test found a problem. It may be done:
The cone biopsy may remove all of the abnormal tissue. If this happens, you won't need more treatment. But if some abnormal cells are left in the cervix after the biopsy, more tissue may need to be removed. If follow-up tests show normal cells, then no further treatment will be needed. If abnormal cells remain, you and your doctor may discuss other treatments, such as removal of the uterus (hysterectomy).
The cone biopsy may show cancer that has grown deep into the cervical tissue (cervical cancer). Further treatment, such as surgery, radiation, or chemotherapy, will be recommended.
A cone biopsy is a surgical treatment with some risks.
