What is Cervical Cancer? Symptoms, the HPV Vaccine, and Pap Smear Tests

Cervical cancer develops in the cervix—the lower part of the female reproductive system—but it is entirely preventable when caught early. Thanks to regular Pap smears and HPV DNA screenings, precancerous cells can be detected long before they become dangerous. Meanwhile, the HPV vaccine significantly eliminates the risk of the disease ever emerging. Today, one of the medical world's greatest goals is to turn this disease into a mere footnote in medical history books for future generations through proper screening and vaccination programmes.

In Brief:

• The primary cause of the disease is almost entirely the Human Papillomavirus (HPV) infection.
• It typically progresses slowly over many years, often showing no symptoms in its early stages.
• Pap smear and HPV DNA tests detect cellular changes long before they turn into cancer.
• The HPV vaccine can be safely administered to both girls and boys starting from the age of 9.
• With early diagnosis and the treatment of precancerous lesions, the success rate is close to one hundred per cent.

What is Cervical Cancer?

The cervix is the cylinder-shaped tissue at the lower part of the uterus that opens into the vagina. Cervical cancer occurs when healthy cells in this area undergo genetic changes and multiply uncontrollably, usually due to a persistent viral infection. The greatest advantage in fighting this disease is that it typically takes a very long time—often 10 to 15 years—for a normal cell to transform into a cancerous one.

This long transition period offers a wide window of opportunity for medical intervention. Precancerous cellular abnormalities (dysplasia) can be easily detected during regular gynaecological examinations. The World Health Organization emphasises that with the right screening and vaccination strategies, this type of cancer can be eliminated as a global public health problem. When diagnosed early, it is possible to simply clear the diseased area without removing the cervix or damaging the uterus.

Causes and Risk Factors

The most fundamental known cause of cervical cancer is a sexually transmitted Human Papillomavirus (HPV) infection. Although there are hundreds of HPV types in nature, HPV Types 16 and 18 are responsible for about seventy per cent of all cervical cancers. Most women's immune systems clear this virus from the body within a few years. However, when the virus cannot be eliminated and turns into a persistent infection, structural breakdown in the cells begins.

There are several risk factors that accelerate the progression of an HPV infection to cancer. Smoking is at the top of this list; harmful substances in tobacco products accumulate in cervical fluids and weaken the immune cells in the area. Diseases that suppress the immune system, an early start to sexual activity, a history of multiple partners, and long-term use of birth control pills are among other factors that increase the risk. Genetic predisposition plays a much smaller role in this type of cancer compared to other gynaecological diseases.

What are the Symptoms of Cervical Cancer?

The most dangerous aspect of the disease is that precancerous lesions and early-stage cancers generally cause no complaints. Cellular changes progress silently. However, as the tumour begins to grow and spread to surrounding tissues, various cervical cancer symptoms emerge. The most common early-stage symptom is abnormal vaginal bleeding that occurs outside the regular menstrual cycle. Spotting-style bleeding, especially after sexual intercourse, should be taken seriously.

As the disease progresses, the severity and variety of symptoms increase. Any bleeding that occurs after menopause is a serious warning sign. Menstrual bleeding that lasts longer and is heavier than normal, along with foul-smelling, watery, or bloody vaginal discharge, are frequently seen. In advanced stages, as the tumour presses on nerves in the pelvic region, groin pain, pain during sexual intercourse (dyspareunia), and pain radiating to the lower back and legs may be felt. If you experience any of these complaints, you should consult a gynaecologist without delay.

Life-Saving Screening Tests: Pap Smear and HPV DNA

The most effective way to protect against cervical cancer is to detect cellular abnormalities before the cancer process begins. The Pap Smear test is a painless procedure where cells shed from the cervix are collected with a small brush and examined under a microscope. The HPV DNA test involves looking for the genetic material of the virus from the exact same swab sample. These tests take only a few minutes in an outpatient clinic and do not require anaesthesia. For more detailed information on this topic, you can review our article titled Just 5 Minutes, a Lifetime of Health: The Vital Importance of the Smear Test.

According to international guidelines, screening programmes should be conducted within specific age ranges and frequencies. It is recommended that every woman from the age of 21 has a Pap Smear test every 3 years. For women between the ages of 30 and 65, the ideal approach is "co-testing," where the Pap Smear and HPV DNA tests are performed together; this dual screening should be repeated every 5 years. If only a Smear test is to be performed, it should continue every 3 years. For women whose regular screenings have been normal up to the age of 65, the screening programme may be concluded with a doctor's approval.

The HPV Vaccine: Who Should Get It, At What Age, and How Many Doses?

The HPV vaccine is the strongest protective shield developed against cervical cancer. The vaccine trains the immune system against the most dangerous types of the virus, preventing the infection from taking hold. Ideally, the vaccine should be administered before sexual activity begins. The World Health Organization recommends that girls and boys between the ages of 9 and 14 be vaccinated. Vaccinating boys not only protects them from other HPV-related cancers but also stops the circulation of the virus within the community. For details on this subject, you can take a look at our content titled Men's Invisible Problem: The “Relapse” Riddle in HPV and Wart Treatment.

The vaccination schedule varies according to age. When vaccination begins between the ages of 9 and 14, a total of 2 doses administered 6-12 months apart provide sufficient protection. If vaccination starts after the age of 15, a total of 3 doses should be administered at 0, 1-2, and 6 months. Women who have started their sexual life or have previously had an HPV infection can also be vaccinated up to the age of 45. The vaccine does not treat an existing infection, but it provides strong protection against other high-risk HPV types that the person has not yet encountered.

Treatment Methods and the Recovery Process

The treatment for cervical cancer changes entirely depending on the stage at which the disease is caught. If precancerous cells (CIN 2, CIN 3) are detected in screening tests, simple surgical procedures such as LEEP (removing the diseased tissue with a thin electrical wire) or cold conization are performed. These procedures preserve the integrity of the uterus, and patients can usually return home the same day and resume their normal lives within a few days.

If the disease has progressed to the cancer stage, more comprehensive treatments are planned based on the size and spread of the tumour. For early-stage cancers, surgical removal of the uterus, cervix, and surrounding lymph nodes (hysterectomy) may be necessary. In advanced stages, rather than surgical intervention, combinations of radiotherapy (radiation treatment) and chemotherapy (drug treatment) come into play. The recovery process after oncological treatments administered in the hospital can take weeks or months. During this process, the patient's nutrition, psychological support, and regular oncology follow-ups are of vital importance.

Complications and Risk Groups

Untreated cervical cancer spreads rapidly to surrounding organs, leading to serious complications. When the tumour spreads to the bladder or the rectum (the final section of the large intestine), difficulty urinating, bloody urine, or bowel obstructions may occur. Furthermore, kidney failure can develop as a result of blockages in the kidney ducts. In advanced stages, the disease can spread (metastasise) to the lungs, liver, and bones, reaching life-threatening proportions.

The treatments applied also carry their own unique risks. After extensive surgeries or pelvic radiotherapy, issues such as loss of fertility, early menopause, vaginal dryness, and urinary incontinence may be experienced. Individuals in high-risk groups (long-term smokers, those with immunodeficiency, those engaging in unprotected sexual intercourse) are more likely to encounter these complications. Therefore, strictly adhering to screening programmes is the only way to minimise potential risks.

When to See a Doctor

Gynaecological examinations should be performed according to a routine screening schedule, not just when there is a complaint. However, when certain symptoms appear, you should consult a doctor immediately without waiting for your next check-up appointment. A single drop of bleeding during menopause, bleeding during or immediately after sexual intercourse, irregular spotting between menstrual cycles, and foul-smelling, meat-broth-coloured vaginal discharge are conditions that require urgent evaluation.

In some situations, it is vital to go directly to the emergency room or call 112. Severe vaginal bleeding that completely fills one or more pads within an hour, passing large clots along with the bleeding, or sudden and unbearable groin or abdominal pain require emergency medical intervention. If you experience dizziness, blackouts, cold sweats, and a feeling of fainting (symptoms of haemorrhagic shock) due to excessive bleeding, you should reach the nearest healthcare facility without losing any time.

Frequently Asked Questions

Does the HPV vaccine definitively prevent cervical cancer?

The HPV vaccine provides over 90% protection against the high-risk virus types that most frequently cause cervical cancer. However, because the vaccine does not cover all HPV types, you must continue your routine smear and HPV screening tests even if you have been vaccinated.

Is a smear test a painful procedure?

No, a smear test is absolutely not a painful or hurtful procedure. During a gynaecological examination, a swab is taken from the cervix in seconds using a small brush with a soft tip; during this time, you will only experience a slight touching sensation.

Is cervical cancer passed genetically from mother to daughter?

The genetic or hereditary transmission of cervical cancer is almost non-existent compared to breast or ovarian cancers. The primary cause of the disease is not genetic inheritance, but an acquired Human Papillomavirus (HPV) infection.

Can women who are virgins have a smear test or HPV screening?

Because a smear test is performed by reaching the cervix through the vaginal canal, it can damage the hymen. Therefore, routine smear tests are not performed on virgin women. However, if there is unusual bleeding or other complaints, a doctor can evaluate the situation using different examination methods.

If my HPV test is positive, does it mean I definitely have cancer?

A positive HPV test does not mean you have cancer; it merely indicates that this virus is present in your body. Most HPV infections are cleared by the immune system without causing any cellular deterioration. In the case of a positive result, your doctor will check the condition of the cells with advanced examinations such as a colposcopy.
