Why pap smear is important

Doctors recommend repeating examination every two years as it can detect changes in IT CAN cervical cells that suggest cancer may develop.

Let us first define what cancer of the cervix is. The cervix is the lower part of the uterus that opens into the vagina.

Cervical cancer occurs when abnormal cells on the cervix grow out of control. Cervical cancer can often be successfully treated when it’s found early. It is usually found at a very early stage through a pap smear test.

This cancer of the cervix is caused by the human papilloma virus (HPV) and you can get HPV by having sexual contact with someone who has it.

Most adults have been infected with HPV at some stage of their lives. An infection may go away on its own, but sometimes it can cause genital warts or lead to cervical cancer.

That is why it’s important for women to have regular pap tests.

The following factors increase the risk of getting cancer of the cervix:

  • Having an ongoing infection. A high-risk type of HPV.
  • High-risk sexual behaviours. These include having more than one sex partner or having a sex partner who has more than one. Safer sex can reduce your risk.
  • Having an impaired immune system. Some conditions such as HIV can make you more likely to get an HPV infection.
  • Smoking cigarettes.

A pap smear, also called a pap test, is a procedure to test for cervical cancer in women. It involves collecting cells from your cervix, the lower, narrow end of your uterus that’s at the top of your vagina.

Detecting cervical cancer early with a pap smear gives you a greater chance at a cure. A pap smear can also detect changes in your cervical cells that suggest cancer may develop in the future. Detecting these abnormal cells early with a pap smear is your first step in stopping the possible development of cervical cancer.

How the test is done

The test is performed in your doctor’s office and takes a few minutes. You will be asked to lie down on your back on an exam table with your knees bent. Your heels rest in supports called stirrups.

Your doctor will gently insert an instrument called a speculum into your vagina. The speculum holds the walls of your vagina apart so that your doctor can easily see your cervix. Inserting the speculum may cause a sensation of pressure in your pelvic area. Then your doctor will take samples of your cervical cells using a soft brush or a flat scraping device called a spatula.

It is not a painful procedure, but may be slightly uncomfortable. After the test is done, you can go about your day without restrictions. Depending on the type of pap testing you’re undergoing, your doctor transfers the cell sample into a container holding a liquid to preserve the sample (liquid-based pap test) or onto a glass slide (conventional pap smear).

The samples are then taken to a laboratory where they are examined under a microscope to look for characteristics in the cells that indicate cancer or a precancerous condition.

Who should have a pap smear?

It is recommended that one begins pap testing at age 21, or any time after starting to have sexual intercourse. Doctors recommend repeating Pap testing every two years for women ages 21-65. If you have any of the aforementioned risk factors, your doctor may recommend more frequent pap smears, regardless of your age.

You and your doctor can discuss the benefits and risks of pap smears and decide what’s best for you based on your risk factors. Doctors agree that women can consider stopping routine pap testing at age 65 if their previous tests for cervical cancer have been negative.

Discuss your options with your doctor and together, you can decide what’s best for you based on your risk factors. If you’re sexually active with multiple partners, the doctor may recommend continuing to test.

Risks

A pap smear is a safe way to screen for cervical cancer. However, a pap smear is not full proof. It is possible to receive false-negative results, meaning that the test indicates no abnormality, even though you do have abnormal cells.

A false-negative result does not mean that a mistake was made.

Factors that can cause a false-negative result include:

  • An inadequate collection of cells.
  • A small number of abnormal cells.
  • Blood or inflammatory cells obscuring the abnormal cells.
  • Although it’s possible for abnormal cells to go undetected, time is on your side. Cervical cancer takes several years to develop. And if one test doesn’t detect the abnormal cells, the next test most likely will.

To ensure that your pap smear is most effective, follow these tips prior to your test:

  • Avoid intercourse, douching, or using any vaginal medicines or spermicidal foams, creams or jellies for two days before having a pap smear, as these may wash away or obscure abnormal cells.
  • Try not to schedule a pap smear during your menstrual period. Although the test can be done, it’s best to avoid this time of your cycle, if possible.

Results

A pap smear can alert your doctor to the presence of suspicious cells that need further testing. If only normal cervical cells were found, you are said to have a negative result. You will not need any further treatment or testing until you are due for your next pap smear and pelvic exam.

If abnormal cells were found during your pap smear, you’re said to have a positive result. A positive result does not mean you have cervical cancer. It depends on the type of cells found in your test. If your pap smear is abnormal, your doctor may perform a procedure called colposcopy, using a special magnifying instrument (colposcope) to examine the tissues of the cervix, vagina and vulva.

Your doctor also may take a tissue sample (biopsy) from any areas that appear abnormal. The tissue sample is then sent to a laboratory for analysis and a definitive diagnosis.
