Cervical cancer is one of the most preventable forms of cancer, yet it remains a major cause of illness and death among women worldwide. The disease develops in the cells of the cervix the lower part of the uterus that connects to the vagina. In its early stages, cervical cancer often causes no symptoms, making regular screening and vaccination against the Human Papillomavirus (HPV) essential for early detection and prevention.
Health experts say that when cervical cancer is diagnosed early, treatment is often highly successful.
What Is Cervical Cancer?
Cervical cancer occurs when abnormal cells in the cervix grow uncontrollably and form a tumour.
Most cases develop gradually over several years, beginning with precancerous changes that can be detected through routine cervical screening before they become cancer.
What Causes Cervical Cancer?
The main cause of cervical cancer is a persistent infection with certain high-risk types of the Human Papillomavirus (HPV).
HPV is a common virus that is primarily spread through sexual contact. In many people, the immune system clears the infection naturally. However, when high-risk HPV infections persist, they can cause abnormal changes in cervical cells that may eventually develop into cancer.
Risk Factors
Factors that increase the risk of cervical cancer include:
- Persistent high-risk HPV infection.
- Smoking.
- Having multiple sexual partners.
- A weakened immune system, including HIV infection.
- Long-term use of certain hormonal contraceptives.
- Giving birth to several children.
- Not attending regular cervical screening.
Having one or more risk factors does not mean a woman will develop cervical cancer.
Early Warning Signs
Cervical cancer may not cause symptoms in its early stages.
As the disease progresses, symptoms may include:
- Bleeding between menstrual periods.
- Bleeding after sexual intercourse.
- Bleeding after menopause.
- Unusually heavy or prolonged menstrual periods.
- Persistent watery, bloody, or foul-smelling vaginal discharge.
- Pelvic pain.
- Pain during sexual intercourse.
These symptoms can also be caused by conditions other than cancer, but they should always be evaluated by a healthcare professional.
How Is Cervical Cancer Diagnosed?
A healthcare provider may recommend:
- A pelvic examination.
- A Pap smear (cervical screening test).
- HPV testing.
- Colposcopy to closely examine the cervix.
- A biopsy to confirm the diagnosis.
- Imaging tests such as CT, MRI, or PET scans if cancer is suspected to have spread.
Early diagnosis greatly improves treatment outcomes.
Treatment Options
Treatment depends on the stage of the cancer, the woman’s age, and her overall health.
Options may include:
Surgery
Surgery may be performed to remove the cancer while preserving fertility in selected early-stage cases, or to remove the uterus in more advanced cases.
Radiotherapy
High-energy radiation is used to destroy cancer cells.
Chemotherapy
Anti-cancer medicines may be given alone or together with radiotherapy to improve treatment outcomes.
Targeted Therapy and Immunotherapy
Some women with advanced cervical cancer may benefit from newer treatments that specifically target cancer cells or help the immune system fight the disease.
Can Cervical Cancer Be Prevented?
Many cases can be prevented through:
- HPV vaccination, ideally before exposure to the virus.
- Regular cervical screening (Pap smear and HPV testing).
- Avoiding smoking.
- Practising safer sex.
- Prompt treatment of precancerous cervical changes.
Prevention remains the most effective strategy against cervical cancer.
When Should You See a Doctor?
Seek medical advice immediately if you experience:
- Bleeding after sexual intercourse.
- Bleeding after menopause.
- Persistent abnormal vaginal discharge.
- Ongoing pelvic pain.
- Unexplained bleeding between periods.
Do not wait for symptoms to worsen before seeking medical care.
The Bottom Line
Cervical cancer is largely preventable through HPV vaccination and regular cervical screening. Because early stages often produce no symptoms, routine check-ups are essential for detecting abnormal changes before they become cancer. Women who notice abnormal bleeding, unusual vaginal discharge, or persistent pelvic pain should seek prompt medical evaluation, as early diagnosis offers the best chance of successful treatment.
