If you're a woman 21 or over, it's important to begin getting regular pelvic examinations to take charge of your health. An important part of this pelvic exam may include a test, called a Pap smear, to detect the often life-threatening disease, cervical cancer, even before it starts. And here's the key, cervical cells become abnormal years before they turn to cancer. That gives an excellent window of opportunity.
So, what is a Pap smear?
A Pap smear is a microscopic examination of cells scraped from the opening of the cervix. The cervix is the lower part of the uterus, or womb, that opens at the top of the vagina. The test looks for cervical cancer or abnormal cells. Most cervical cancers can be found, and treated early, or even before they start, if women have routine Pap smears and pelvic examinations.
For this test, you will lie on a table and place your feet in stirrups. The doctor will insert an instrument called a speculum into the vagina and open it slightly to see inside the vaginal canal. Cells are gently scraped from the cervix area, and sent to a lab for examination.
When a Pap smear shows abnormal changes, you will need further testing. The next step depends on the results of the Pap smear, and on your previous history of Pap smears, and risk factors you may have for cervical cancer. You may need a biopsy using a light and a low-powered microscope, called colposcopy. You may also need a test to check for infection with human papilloma virus, or HPV, which can cause cervical cancer.
If you are diagnosed with cervical cancer, the doctor will order more tests to determine how you should be treated, and how far the cancer has spread. This is called staging. Treatment will depend on the stage of the cancer, the size and shape of the tumor, your age and general health, and your desire to have children in the future.
Early cervical cancer can be treated with surgery to remove the abnormal tissue, or freeze abnormal cells, or burn abnormal tissue. Treatment for more advanced cervical cancer may include radical hysterectomy, removal of the uterus and much of the surrounding tissue, including lymph nodes and the upper part of the vagina. Radiation may be used to treat cancer that has spread beyond the pelvis, or if cancer returns. The woman may also have chemotherapy to kill the cancer if the cervical cancer's advanced.
The Pap smear test is not 100% accurate and cervical cancer may be missed in a small number of cases. Fortunately, cervical cancer develops very slowly in most women and follow-up Pap smears should identify worrisome changes in plenty of time for treatment. Make sure your doctor knows about all the medicines you are taking. Some, including estrogen and progestins, may affect the result of your Pap smear.
Pap smears can be a wonderful, life saving tool.
