What is Cervical Cancer?
Cervical cancer develops in the cells of the cervix — the lower part of the uterus that connects to the vagina. It is one of the most common gynaecologic cancers and typically develops slowly over time, often from precancerous changes that, if detected early, can be treated before they become malignant.
The good news is that cervical cancer is one of the most preventable cancers. With regular screening through Pap smears, HPV testing, and vaccination, the vast majority of cases can be caught early or avoided altogether. Awareness, routine check-ups, and timely action are the most powerful tools available.
Types of Cervical Cancer
Cervical cancer is classified by the type of cells in which it originates within the cervix. Each subtype behaves differently and may respond to treatment in a distinct way.
Primary Cervical Cancer Types
4 subtypesSquamous Cell Carcinoma
Originates in the thin, flat cells lining the outer part of the cervix. Accounts for the majority of cases.
Adenocarcinoma
Develops in the glandular cells that produce mucus. Increasingly common in younger women.
Adenosquamous Carcinoma
A less common type containing both squamous and glandular cancer cells simultaneously.
Small Cell Cervical Cancer
A rare and aggressive form that requires prompt, intensive treatment upon diagnosis.
The HPV Connection
Over 99% of cervical cancers are linked to persistent infection with high-risk strains of the Human Papillomavirus (HPV) — particularly HPV-16 and HPV-18. HPV vaccination and regular Pap smear screening are the most effective tools for prevention and early detection.
Symptoms of Cervical Cancer
Early-stage cervical cancer often produces no symptoms at all — underscoring the critical importance of routine screening. As the disease progresses, the following signs may appear:
Causes & Risk Factors
While HPV infection is the primary driver, several additional factors can increase a woman's risk of developing cervical cancer:
HPV Infection
Persistent infection with high-risk HPV strains — especially HPV-16 and HPV-18 — is the leading cause, present in over 99% of cervical cancer cases.
Smoking
Smoking weakens the immune system's ability to fight HPV and introduces carcinogens into cervical tissue, significantly raising cancer risk.
Weak Immune System
Conditions such as HIV/AIDS or use of immunosuppressive medications reduce the body's ability to clear HPV infections.
Multiple Sexual Partners
A higher number of sexual partners increases the likelihood of HPV exposure and subsequent persistent infection.
Early Sexual Activity
Beginning sexual activity at a young age may increase cumulative HPV exposure during a period when the cervix is more susceptible.
Long-Term Oral Contraceptive Use
Extended use of hormonal birth control pills for 5 or more years may slightly increase the risk of cervical cancer.
Family History
A family history of cervical cancer may indicate a genetic susceptibility that increases an individual's own risk.
Lack of Regular Screening
Women who do not undergo routine Pap smears or HPV testing are at far greater risk of cervical cancer going undetected until a later stage.
Screening & Early Detection
Cervical cancer is unique in that it can often be detected — and prevented — before it fully develops. Regular screening allows doctors to identify precancerous changes and treat them before cancer forms. The following tests are used:
Pap Smear Test
Collects cervical cells to detect abnormal changes before they become cancerous. Recommended every 3 years from age 21.
HPV Testing
Identifies the presence of high-risk HPV strains. Often combined with Pap testing (co-test) for women over 30.
Colposcopy
A detailed examination of the cervix under magnification when Pap or HPV results are abnormal.
Cervical Biopsy
Removal of a small tissue sample from the cervix to confirm the presence of cancerous or precancerous cells.
Imaging (CT / MRI / PET)
Used after diagnosis to stage the cancer — determining its size and whether it has spread to lymph nodes or other organs.
Pelvic Examination
Routine physical check to assess the size and condition of the uterus, cervix, and surrounding structures.
HPV Vaccination — Your Best Prevention
The HPV vaccine (Gardasil / Cervarix) provides strong protection against the strains responsible for most cervical cancers. It is most effective when administered before the onset of sexual activity, typically recommended for girls and women aged 9–26. Vaccination combined with regular screening can prevent the vast majority of cervical cancer cases.
Stages of Cervical Cancer
Staging describes how far the cancer has spread and directly shapes the treatment approach. Cervical cancer is staged using the FIGO system, developed by the International Federation of Gynecology and Obstetrics, alongside the AJCC TNM system. This staging guidance is current as of 2026.
Cancer is confined to the cervix and has not spread beyond it.
Cancer has spread beyond the cervix and uterus, but not to the pelvic wall or lower third of the vagina.
Cancer has spread to the pelvic wall, the lower third of the vagina, or nearby lymph nodes.
Cancer has spread to nearby organs such as the bladder or rectum, or to distant organs such as the lungs or bones.
Source: American Cancer Society, Cervical Cancer Stages. FIGO staging is periodically updated — treatment planning is always based on the most current staging criteria at the time of diagnosis.
Survival Rates by Stage
An important note on statistics. Survival statistics are population averages. They describe outcomes across large groups of patients and do not predict what will happen to any individual patient.
Cervical cancer survival rate in the United States
| Stage at Diagnosis | 5-Year Relative Survival |
|---|---|
| Localized — confined to the cervix | 92% |
| Regional — spread to nearby structures or lymph nodes | 62% |
| Distant — spread to other organs | 19% |
Source: American Cancer Society, Cervical Cancer Survival Rates, based on SEER data for cases diagnosed between 2015 and 2021.
Cervical cancer survival rate in India
India has a substantial and well-documented cervical cancer burden, and published research citing National Cancer Registry Programme data reports an overall 5-year relative survival rate of approximately 46 percent, with significant regional variation ranging from 34.5 percent in Bhopal to 59.6 percent in Chennai. This gap compared with the United States figure above is closely tied to stage at diagnosis, since a large proportion of cases in India are still detected at Stage III or later.

Treatment Options for Cervical Cancer
Treatment depends on the cancer's stage, type, and the patient's overall health and fertility goals. Dr. Aditya Sarin builds a personalised, multidisciplinary plan that aims for the most effective and least invasive approach for each case:
Surgery
Procedures range from cone biopsy or LEEP (early stages) to hysterectomy for more advanced disease.
Radiation Therapy
Precisely targeted high-energy rays to destroy cervical cancer cells, used alone or alongside chemotherapy.
Chemotherapy
Drug therapy to kill or shrink cancer cells, commonly combined with radiation (chemoradiation) for enhanced results.
Targeted Therapy
Bevacizumab and, in recurrent/metastatic disease, tisotumab vedotin target specific molecular drivers of tumour growth.
Immunotherapy
Checkpoint inhibitors such as pembrolizumab help the immune system recognise and attack cervical cancer cells.
For women of reproductive age who wish to preserve fertility, fertility-sparing surgical options such as radical trachelectomy may be considered in carefully selected early-stage cases. Detailed fertility counselling is part of the treatment planning process.
Latest Advances in Cervical Cancer Treatment
Treatment for recurrent and metastatic cervical cancer has expanded meaningfully over the past two years, particularly with the first antibody-drug conjugate approved for this cancer. As of 2026, the notable development is the following.
Full Approval for a Targeted Therapy After Chemotherapy
Tisotumab vedotin, the first antibody-drug conjugate approved for cervical cancer, received full FDA approval in April 2024 for recurrent or metastatic cervical cancer that has progressed after chemotherapy, based on Phase 3 trial data. In that trial, median overall survival was 11.5 months with tisotumab vedotin compared with 9.5 months with chemotherapy, and it remains a standard second-line option as of 2026, alongside pembrolizumab-based combinations used earlier in treatment.
