Cervical cancer is one of the leading causes of cancer-related deaths among women worldwide. According to the World Health Organization (WHO), more than 300,000 women die from cervical cancer each year, and approximately 500,000 new cases are diagnosed globally. Despite significant advances in prevention and treatment, the disease continues to pose a major health threat. Early detection, prevention strategies like HPV vaccination, and effective treatments have drastically reduced its impact in high-income countries. However, the numbers remain high in low-income regions where access to healthcare may be limited.
In this blog, we will explore the key causes, signs and symptoms, stages, and treatment options for cervical cancer, as well as its rising trend, and how you can take proactive steps in preventing it.
Key Takeaways:
- HPV infection is the primary cause of cervical cancer, and the HPV vaccine is a key prevention tool.
- Regular Pap smears and HPV testing can help detect cancer early, when it is most treatable.
- HIV and other STDs increase the risk of cervical cancer, as they can weaken the immune system and increase HPV persistence.
- Surgery, radiation, and chemotherapy are the main treatments, depending on the cancer stage.
- Prevention through vaccination, regular screenings, and lifestyle changes are crucial in reducing the burden of cervical cancer.

What is Cervical Cancer?
Cervical cancer develops in the cervix, the lower part of the uterus that connects to the vagina. It most commonly occurs due to persistent infection with high-risk strains of Human Papillomavirus (HPV). HPV is a sexually transmitted infection (STD) that, when left untreated, can cause abnormal cell changes on the cervix, leading to cancer.
The introduction of the HPV vaccine has played a pivotal role in reducing the rates of cervical cancer by preventing HPV infections. However, despite vaccination efforts, cervical cancer remains a significant health challenge, especially in low and middle-income countries where screening and vaccination rates are still low.
Why is Cervical Cancer Becoming a Growing Concern?
Despite declining in certain areas due to better awareness and screening, the global incidence of cervical cancer remains concerning due to several factors:
- Inconsistent HPV Vaccination: According to WHO, HPV causes 99% of cervical cancer cases, yet many regions still report low vaccination rates. Access to vaccines is limited, especially in lower-income countries, which leads to higher incidence rates.
- Lack of Access to Screening: Regular Pap smears and HPV testing are critical for early detection, but many women in low-income areas do not have access to these screenings. Without them, precancerous cells are often missed until the disease is advanced.
- HIV and STDs: Women with HIV or other STDs are at an increased risk for cervical cancer. A weakened immune system caused by HIV makes it harder for the body to fight off HPV infections, leading to a higher chance of cervical cancer development.
- Delayed Diagnosis and Limited Awareness: Women in the early stages of cervical cancer may not experience symptoms. In such cases, the cancer can go undiagnosed and untreated until it has advanced significantly.
Key Causes & Risk Factors of Cervical Cancer
Several factors contribute to the development of cervical cancer, with HPV infection being the leading cause. Other risk factors include:
- Persistent HPV Infection: Long-term infection with high-risk HPV strains, especially types 16 and 18, increases the likelihood of cervical cancer.
- Multiple Sexual Partners: Having multiple sexual partners or engaging in unprotected sex increases the risk of HPV infection.
- Weakened Immune System: Women with HIV or other conditions that suppress the immune system are more susceptible to HPV infections that may lead to cancer.
- Smoking: Smoking damages the cervix and weakens the immune system, increasing the risk of cervical cancer.
- Oral Contraceptive Use: Long-term use of birth control pills has been associated with a slightly higher risk of cervical cancer.
- Family History: Women with a family history of cervical cancer may be at greater risk, potentially due to inherited genetic factors.
Common Symptoms of Cervical Cancer
In its early stages, cervical cancer typically does not cause noticeable symptoms. As the disease progresses, women may begin to experience the following signs:
- Abnormal Vaginal Bleeding: This includes bleeding between periods, after sexual intercourse, or post-menopause.
- Unusual Vaginal Discharge: A foul-smelling, watery, or bloody discharge may be present.
- Pain During Intercourse: Painful sexual activity may occur due to the tumor’s growth in the cervix.
- Pelvic Pain: This persistent discomfort can be a sign of advanced cancer.
- Fatigue and Weight Loss: As the cancer spreads, women may experience unexplained weight loss and fatigue.
Cervical Cancer Stages
Cervical cancer is classified into stages based on how far the cancer has spread. The stages help doctors determine the best course of treatment. The most commonly used system for staging is the FIGO system:
- Stage 0 (Carcinoma in situ): The cancer is confined to the cervix and has not spread to other tissues.
- Stage I: The cancer is still localized to the cervix and uterus.
- Stage II: The cancer has spread beyond the cervix, but still within the pelvic region.
- Stage III: The cancer extends to the lower part of the vagina or pelvic wall.
- Stage IV: The cancer has spread to distant organs, such as the bladder, rectum, or other areas outside the pelvic region.
Staging is essential to determine the most appropriate treatment options for the patient.
Types of Cervical Cancer
There are two main types of cervical cancer:
1. Squamous Cell Carcinoma:
The most common form, it starts in the thin, flat cells lining the cervix. It accounts for about 70-90% of all cervical cancer cases.
2. Adenocarcinoma:
This type originates in the mucus-producing cells of the cervix. While less common, it is often more difficult to detect and treat.
In some cases, women may have a mixture of both types of cervical cancer, known as adenosquamous carcinoma.
Tests to Diagnose Cervical Cancer
Diagnosing cervical cancer typically involves several steps, including:
- Pap Smear (Pap Test): This is the primary screening test for cervical cancer. It involves collecting cells from the cervix to look for abnormalities.
- HPV Test: This test detects the presence of high-risk HPV strains in cervical cells. It can be done alongside a Pap smear or separately.
- Blood Test: While not a primary test for cervical cancer, certain blood tests can be used to assess overall health and detect potential markers that may suggest cancer or other related conditions.
- Colposcopy: If abnormal cells are found in the Pap test, a colposcopy is performed to examine the cervix more closely. A biopsy may be taken for further analysis.
- Biopsy: A biopsy involves removing a small sample of tissue from the cervix for testing, which helps confirm whether cancer is present.
Can Cervical Cancer Be Cured Completely?
Yes, cervical cancer can be cured if detected in the early stages. Treatment options such as surgery, radiation therapy, and chemotherapy can effectively treat the disease, particularly when the cancer has not spread beyond the cervix. The likelihood of a complete cure is highest when the cancer is detected early, which is why regular screening is essential.

What Are the Survival Rates for Cervical Cancer?
The survival rates for cervical cancer vary significantly based on the stage at diagnosis. According to the National Cancer Institute (NCI), the overall 5-year relative survival rate for cervical cancer is approximately 67%. Source: https://www.cancer.gov/types/cervical/survival
However, survival rates improve substantially when the cancer is detected at an early stage:
- Localized Stage (Stage I): When the cancer is confined to the cervix and has not spread to nearby tissues or lymph nodes, the 5-year relative survival rate is about 91%.
- Regional Stage (Stage II): If the cancer has spread to nearby tissues or lymph nodes, the 5-year relative survival rate decreases to approximately 58%.
- Distant Stage (Stage III and IV): For cancers that have spread to distant parts of the body, the 5-year relative survival rate is around 19%.
Early detection through regular screenings and timely treatment significantly increases the likelihood of survival. It’s crucial for women to engage in routine cervical cancer screenings, such as Pap smears and HPV tests, to identify any abnormalities at the earliest possible stage.

Treatment Options for Cervical Cancer
The treatment for cervical cancer depends on the stage and extent of the disease. The main treatment modalities include:
- Surgery: For early-stage cervical cancer, surgery is the preferred option. A hysterectomy (removal of the uterus) may be performed, along with removal of nearby lymph nodes.
- Radiation Therapy: High-energy radiation is used to kill cancer cells and shrink tumors. It can be used alone or in combination with chemotherapy for more advanced stages.
- Chemotherapy: Chemotherapy uses drugs to destroy or slow the growth of cancer cells. It is often used when the cancer has spread beyond the cervix.
- Immunotherapy: This treatment strengthens the body’s immune system to recognize and destroy cancer cells. It is used in more advanced or recurrent cervical cancer.
- Targeted Therapy: Targeted drugs specifically address the mechanisms that allow cancer cells to grow, making them particularly effective for advanced stages of cervical cancer.
Treatment Team for Cervical Cancer
Cervical cancer treatment requires a multidisciplinary team approach. The treatment team includes:
- Oncologists (cancer specialists)
- Surgeons (who perform surgeries such as hysterectomy)
- Radiation Oncologists (specialists in radiation therapy)
- Medical Oncologists (who administer chemotherapy)
- Nurses and Social Workers (for patient support)
- Pathologists (who diagnose the cancer by examining biopsy samples)
Prevention and Early Detection
Preventing cervical cancer is possible through vaccination, regular screening, and lifestyle changes. Here’s what women can do:
- HPV Vaccination: The HPV vaccine is highly effective at preventing infection with the virus strains that cause cervical cancer. It is recommended for girls and boys aged 11-12 before they become sexually active.
- Regular Screenings: Pap smears and HPV tests are essential for detecting cervical abnormalities before they develop into cancer. Women should begin screenings at age 21, and continue every 3-5 years depending on their results.
- Healthy Lifestyle: Avoiding smoking and using condoms during sexual activity can significantly reduce the risk of developing cervical cancer.
Conclusion
Cervical cancer is a preventable and treatable disease when detected early. With the right preventive measures, such as HPV vaccination, regular screenings, and healthy lifestyle choices, women can significantly reduce their risk of developing cervical cancer. It is vital to stay informed about the causes, symptoms, and treatment options for cervical cancer to take control of your health and well-being.
