This surgery involves cutting away a cone of tissue from your cervix to remove all the abnormal cells. This allows the doctor to remove a slightly larger part of the cervix than with a loop (LLETZ) biopsy. A cone biopsy also allows for the cells at the edges of the specimen to be seen clearly through a microscope ensuring that all of the biopsy can be examined be in the laboratory by the histopathologist.
A cone biopsy is usually carried out under a general anaesthetic (very small cone biopsies can be performed under local anaesthetic). The size of the cone changes according to the size of abnormal cervical cells. A vaginal pack will sometimes be put in place in theatre while you are under anaesthetic. This is like a long bandage that puts pressure on the biopsy site and so helps stop any bleeding (a bit like putting pressure on a cut to stop it bleeding). This is removed before you go home. It is advisable to have some painkillers at home (such as you would take for period pains) as some women experience a deep ache and/or tenderness in their pelvis. It is not unusual to feel tired for a few days or even a week or so following a general anaesthetic.
