It is the tissue that lines the inside the uterus (womb). During a period (menstruation), it goes through changes to get ready for a fertilized egg. If an egg does not implant, much of the tissue is shed during the period. The cycle will start again.

You may be given medicine to relax you.
You will lie on a table with your feet in stirrups. A speculum will help to open the vagina. Your cervix may be numbed. A tenaculum is used to grasp the cervix. A tool is passed through the cervix into the womb to collect the cells. The tool your doctor will use depends on which one will gather the cells best. The biopsy will take 10 to 15 minutes.
You may have cramps. You may also feel light-headed. You will need to lie still for 5 to 10 minutes until this feeling is gone.

The test is normal when the sample shows only normal cells.
The test is abnormal when it finds precancerous or cancer cells, growths, an overgrown lining in your womb, or a lining that does not match the menstrual stage you are in. An inconclusive result may happen if you have a vaginal or cervical infection, or not enough cells were tested. You may need another test to confirm the results.
Talk to your doctor about your test results. A test may point to an illness that you do not have. It can also miss an illness that you may have. The doctor will check your symptoms and all test results before making a diagnosis.
