What Is the Cervix and Why Is Screening Important?

The cervix is the lower part of the uterus that opens into the uppermost portion of the vagina. Cervical cancer is one of the most common cancers among women in India and remains a leading cause of cancer-related deaths. This is why cervical cancer screening through the Pap smear test is extremely important for women’s health.

Cause of Cervical Cancer: Human Papilloma Virus (HPV)

The primary cause of cervical cancer is infection with the human papilloma virus (HPV), which is usually acquired through sexual contact during a woman’s reproductive years. Cervical cancer does not develop suddenly. It typically takes several years—often around 10 years—for HPV infection to progress from early cellular changes to precancerous lesions and finally to cancer. This long time frame allows for early detection and timely intervention through regular Pap smear screening.

How the Pap Smear Test Is Performed

The Pap smear test is a simple, quick, and minimally uncomfortable procedure performed during a routine gynecological examination. The woman lies on the examination couch with her knees bent. A speculum is gently inserted into the vagina to visualize the cervix. A small wooden spatula or brush, known as a cervical scraper, is then used to collect cells from the cervix. The collected sample is sent to a laboratory where the cells are examined under a microscope.

Understanding Pap Smear Test Results

Pap smear results can be normal or abnormal. A normal Pap smear indicates healthy cervical cells. An abnormal Pap smear may show mild cellular changes, precancerous lesions, or in rare cases, cervical cancer. Depending on the findings, the gynecologist may recommend further tests such as HPV testing or a colposcopy, where the cervix is examined under magnification and a biopsy may be taken if required.

When and How Often Should a Pap Smear Be Done?

Cervical cancer screening with a Pap smear should begin at the age of 21 years for sexually active women, or three years after the onset of vaginal sexual activity, whichever is earlier. The Pap smear test should be repeated every three years until the age of 65. Screening can be stopped at 65 years if the Pap smear results have been consistently normal for the past 10 years.

Importance of Regular Screening and False-Negative Results

No screening test is perfect, and Pap smear tests can occasionally give false-negative results, meaning abnormal cells may be missed. This is why regular and repeated cervical cancer screening is essential to ensure early detection and prevention.

Conclusion: Preventing Cervical Cancer Through Screening

Cervical cancer is highly preventable and curable when detected early. Regular Pap smear testing, HPV screening, and timely follow-up can significantly reduce the risk of cervical cancer and improve women’s long-term health outcomes.

Get screened, prioritize women’s health, and stay healthy.
