Having a cone biopsy

A cone biopsy is usually done under a general anaesthetic and you may need to stay overnight in hospital.

During the operation, the surgeon cuts a small, cone-shaped piece of tissue from the cervix.

Afterwards, you may have a small pack of gauze (like a tampon) in the vagina to prevent bleeding. You may also have a tube to drain urine from the bladder while the gauze pack is in place. The gauze pack and tube are usually removed within 24 hours. Then you can go home.


The image shows the pelvic area and the position of the vagina, cervix and womb. A narrow opening is shown between the legs. This leads into a narrow space shown inside the pelvis. This space is called the vagina. Above the vagina the space narrows until both sides almost touch. Then it opens again to form a hollow, pear-shaped organ called the womb. At the narrowest area between the vagina and the womb, the lower end of the womb bulges into the top of the vaginal space. The surfaces of the two sides of the bulge are highlighted. This is the cervix. The lowest, central section of the bulge that forms the cervix is marked. This is the area of the cervix treated.
