HPV Infection and Cervical Cancer: What Every Woman Should Know
Human papillomavirus (HPV) infection is one of the most common viral infections transmitted through sexual contact. Most HPV infections are temporary and are cleared naturally by the immune system. However, persistent infection with certain high-risk HPV types can cause changes in the cells of the cervix and, over time, lead to cervical cancer. (World Health Organization)
The good news is that cervical cancer is largely preventable. HPV vaccination, regular cervical cancer screening, and timely treatment of precancerous changes can dramatically reduce the risk.
What is HPV?
Human papillomavirus is a large family of viruses. More than 200 HPV types have been identified, and different types can affect the skin, genital region, anus and throat.
Some HPV types are considered low-risk because they generally do not cause cancer but may cause genital warts. Others are high-risk or oncogenic HPV types because persistent infection can cause precancerous changes and cancer.
HPV 16 and HPV 18 are particularly important high-risk types and are responsible for a substantial proportion of cervical cancers worldwide. (World Health Organization)
How is HPV transmitted?
HPV is primarily transmitted through intimate sexual contact. Transmission can occur through vaginal, anal or oral sexual contact and through close skin-to-skin contact involving the genital area.
Importantly, HPV infection does not necessarily mean that someone has had multiple sexual partners or that their partner has been unfaithful. HPV is extremely common, and an infection may remain undetected for years.
Most HPV infections produce no symptoms, so a person may have HPV without knowing it. (World Health Organization)
What happens after HPV infection?
In most people, HPV infection is transient. The immune system clears the infection naturally, often within one to two years.
The concern arises when a high-risk HPV infection persists.
The progression generally follows this pathway:
HPV infection → Persistent high-risk HPV → Cervical cell changes → Precancerous lesion → Cervical cancer
This process is usually slow. In women with a normal immune system, it commonly takes many years—often around 15–20 years—for persistent infection to progress to cervical cancer. (World Health Organization)
This long window provides an important opportunity for screening to identify and treat precancerous changes before cancer develops.
Does having HPV mean I have cervical cancer?
No.
A positive HPV test does not mean that you have cervical cancer.
It means that HPV has been detected and that further assessment or follow-up may be required depending on the HPV type, cervical cytology, age and previous screening results.
Most HPV-positive women will not develop cervical cancer, particularly when appropriate follow-up and screening are performed.
How does HPV cause cervical cancer?
Persistent high-risk HPV infection can interfere with normal mechanisms that regulate cell growth. The viral proteins E6 and E7 play an important role in disrupting cellular tumour-suppressor pathways. Over time, persistent infection can result in abnormal cervical cells and, in some women, progression to precancer and eventually invasive cancer. (IARC)
However, HPV infection alone is not enough to explain every individual case. Factors such as immune status, smoking and other co-factors can influence whether an infection persists and progresses. (World Health Organization)
What are the symptoms of HPV infection?
Most HPV infections have no symptoms.
Genital warts may occur with certain low-risk HPV types, but the high-risk HPV types associated with cervical cancer usually do not cause visible symptoms.
That is why screening is so important.
A woman can feel completely healthy and still have HPV-related precancerous changes in the cervix.
Symptoms of cervical cancer
Early cervical cancer may also produce few or no symptoms.
Possible warning symptoms include:
Bleeding after sexual intercourse
Bleeding between periods
Unusually heavy or prolonged menstrual bleeding
Bleeding after menopause
Unusual or persistent vaginal discharge
Pelvic pain
Pain during sexual intercourse
In advanced disease, urinary or bowel symptoms, back pain, leg swelling or unexplained weight loss
These symptoms do not automatically indicate cancer, but they should be evaluated by a gynaecologist.
How can cervical cancer be prevented?
There are three important pillars of prevention:
1. HPV vaccination
HPV vaccination prevents infection with important cancer-causing HPV types and is most effective when given before exposure to HPV.
WHO prioritizes HPV vaccination for girls aged 9–14 years. Depending on age, immune status and the national immunization schedule, one, two or more doses may be recommended. (World Health Organization)
HPV vaccination is an important step in cervical cancer prevention—but vaccination does not replace cervical cancer screening because vaccines do not cover every oncogenic HPV type. (WHO)
2. Regular cervical cancer screening
Screening can identify HPV infection or cervical cell abnormalities before cancer develops.
Depending on the woman’s age, risk factors and the screening programme being followed, screening may involve:
HPV testing
Pap smear/cervical cytology
HPV testing combined with cytology
Visual inspection methods in appropriate settings
WHO recommends high-performance HPV-based screening as an important approach to cervical cancer prevention. Screening intervals should follow the applicable national or professional guideline and the individual’s risk profile. (World Health Organization)
3. Timely treatment of precancer
Finding a precancerous cervical lesion does not mean that the woman has cancer.
Precancerous lesions can often be treated effectively, preventing them from progressing to invasive cervical cancer. (World Health Organization)
HPV vaccination and screening work together
A common misconception is:
“I have taken the HPV vaccine, so I don’t need a Pap smear.”
This is incorrect.
HPV vaccination and cervical screening are complementary—not alternatives.
Vaccination reduces the risk of infection with vaccine-covered HPV types, while screening can detect persistent infection or abnormal cervical cells that may still occur.
Both are important components of cervical cancer prevention. (WHO)
Can HPV be treated?
There is currently no routine medication that simply eliminates HPV from the body.
In most people, the immune system clears the infection naturally.
Medical treatment is directed at HPV-related conditions, such as genital warts or cervical precancerous lesions, rather than trying to eradicate the virus itself.
Therefore, if an HPV test is positive, the most important step is appropriate risk-based follow-up, rather than panic.
Can men get HPV?
Yes.
HPV affects both women and men. It can cause genital warts and several HPV-associated cancers, including anal, penile and oropharyngeal cancers.
Vaccination of boys and men can therefore provide direct protection and may also contribute to reducing HPV transmission in the population. (World Health Organization)
Common myths about HPV
Myth 1: “HPV means my partner has been unfaithful.”
Fact: HPV is extremely common and may remain undetected for a long time. A positive HPV test cannot reliably establish when the infection was acquired.
Myth 2: “Only women with multiple partners get HPV.”
Fact: HPV can be acquired through sexual contact with a single partner.
Myth 3: “If I have no symptoms, I don’t have HPV.”
Fact: Most HPV infections cause no symptoms.
Myth 4: “HPV-positive means cancer.”
Fact: HPV infection is not the same as cervical cancer. Most infections clear, but persistent high-risk infection requires appropriate follow-up.
Myth 5: “The HPV vaccine means I never need screening.”
Fact: Screening remains important even after vaccination. (WHO)
When should you see a gynaecologist?
You should consult a gynaecologist if:
Your HPV test is positive
Your Pap smear is abnormal
You have unexplained bleeding, especially after intercourse
You have unusual persistent vaginal discharge
You have genital warts
You have missed recommended cervical screening
You want to discuss HPV vaccination
You have a history of cervical precancer or previous abnormal screening
Depending on your results, your doctor may recommend repeat HPV testing, cytology, colposcopy, biopsy or treatment.
The most important message
HPV infection is common. Cervical cancer is preventable.
A positive HPV test should not be a reason for shame or panic. It should be a reason to complete the recommended evaluation and follow-up.
The combination of HPV vaccination + appropriate cervical screening + timely treatment of precancerous lesions offers powerful protection against cervical cancer. WHO’s global elimination strategy aims to make cervical cancer a rare disease through high vaccination, screening and treatment coverage. (World Health Organization)
Common questions:
Can HPV infection cause cervical cancer?
Yes. Persistent infection with high-risk HPV types is the main cause of cervical cancer. Most HPV infections clear naturally, but persistent high-risk infection can cause precancerous cervical changes.
What does an HPV positive test mean?
An HPV-positive test means that a high-risk HPV type has been detected. It does not mean that you have cervical cancer. Your doctor will recommend appropriate follow-up based on your HPV result, cytology and individual risk.
Can HPV infection be cured?
There is no routine medicine that directly eliminates HPV. In many people, the immune system clears the infection naturally. HPV-related conditions such as genital warts and cervical precancer can be treated.
Does the HPV vaccine prevent cervical cancer?
HPV vaccination significantly reduces the risk of infection with HPV types responsible for many HPV-related cancers. However, vaccination does not replace recommended cervical cancer screening.
Do I need a Pap smear after HPV vaccination?
Yes. HPV vaccination does not eliminate the need for cervical cancer screening according to the recommended screening schedule.
Can HPV occur without symptoms?
Yes. Most HPV infections are asymptomatic. This is one of the main reasons regular cervical cancer screening is important.
Where can I get cervical cancer screening in Chembur?
Women in Chembur and surrounding areas can consult a gynaecologist regarding HPV testing, Pap smear, cervical cancer screening and HPV vaccination based on their age and individual risk factors.
Take-home message
Don’t wait for symptoms.
Get vaccinated against HPV when appropriate, follow your recommended cervical screening schedule, and consult your gynaecologist if you have an abnormal HPV or Pap test.
Early detection can prevent cervical cancer—and prevention is better than treatment.
Women looking for HPV testing, Pap smear, cervical cancer screening or HPV vaccination in Chembur, Mumbai can consult a gynaecologist for personalised advice. Regular screening is particularly important because HPV infection and early cervical precancer may occur without symptoms. Appropriate testing and follow-up can help detect cervical abnormalities early and prevent cervical cancer.
