Cervical cancer is a significant health concern affecting women worldwide. This type of cancer develops in the cervix, the lower part of the uterus that connects to the vagina. Despite being a serious condition, cervical cancer is often preventable and treatable when detected early, making awareness and regular screenings crucial for women’s health.
Understanding the early signs, causes, and treatment options for cervical cancer can save lives. This article explores the key aspects of cervical cancer, including its symptoms, risk factors, and diagnostic methods. It also delves into the latest advancements in treatment and prevention strategies, providing valuable information to help women take control of their health and well-being.
Understanding Cervical Cancer
Cervical cancer develops in the cells of the cervix, which is the lower part of the uterus that connects to the vagina. It usually starts when healthy cells in the cervix gradually develop abnormal changes, known as dysplasia, over time. If not destroyed or removed, these abnormal cells may become cancer cells and start to grow and spread more deeply into the cervix and to surrounding areas.
The two main types of cervical cancer are:
- Squamous cell carcinoma: This type affects the flat cells that cover the outer part of the cervix (ectocervix) and accounts for up to 90% of cervical cancers.
- Adenocarcinoma: This type starts in the glandular cells that line the inner part of the cervix (endocervix) and makes up about 10-20% of cervical cancers.
Less common types include adenosquamous carcinoma, small cell carcinoma, and other rare tumors.

Cervical cancer is staged based on how much cancer there is in the body and where it is located when first diagnosed. The most common staging system is the FIGO system, which has four main stages:
- Stage 1: The cancer is confined to the cervix.
- Stage 2: The cancer has grown beyond the cervix and uterus but has not spread to the pelvic walls or the lower part of the vagina.
- Stage 3: The cancer has spread to the lower part of the vagina or the pelvic walls and may have spread to nearby lymph nodes.
- Stage 4: The cancer has spread to the bladder, rectum, or distant parts of the body.
Early detection through regular screening is crucial for the successful treatment of cervical cancer. Understanding the types and stages of cervical cancer can help in making informed decisions about treatment options and prognosis.
Early Signs and Symptoms
In the early stages, cervical cancer often has no symptoms, making it difficult to detect. Symptoms usually begin after the cancer has spread beyond the cervix. When symptoms of early-stage cervical cancer do occur, they may include:
- Unusual vaginal bleeding, such as:
- Bleeding after intercourse
- Bleeding between periods
- Bleeding after menopause
- Watery, bloody vaginal discharge that may be heavy or have an odor
- Pelvic pain or pain during intercourse
Common early symptoms
One of the most common early symptoms of cervical cancer is abnormal vaginal bleeding. This could range from a faint tinge of pink in otherwise clear vaginal discharge to extremely heavy menstrual periods. Other common symptoms include pelvic pain, feeling bloated or full, and pain that radiates to the legs or back.
Shalee Landry, who was diagnosed with cervical cancer at age 37, experienced watery discharge between her periods and unusually heavy menstrual cycles. She initially attributed these symptoms to stress.
When to see a doctor
It is crucial to consult a healthcare professional if you experience any of the following symptoms:
- Heavier than usual bleeding
- Bleeding between periods
- Bleeding after sex
- Bleeding after menopause
Dr. Jolyn Sharpe Taylor, a gynecologic cancer surgeon, emphasizes the importance of discussing irregularities in your menstrual cycle with your doctor, especially if you experience any of the above symptoms.
Additionally, if you have tested positive for human papillomavirus (HPV), it is essential to stay current on your follow-up appointments. HPV causes several types of cancer, including cervical cancer, and regular monitoring can help detect any abnormalities early on.
Causes and Risk Factors
Cervical cancer has a strong association with certain risk factors, with human papillomavirus (HPV) infection being the primary cause. Understanding these risk factors can help in the prevention and early detection of cervical cancer.
HPV infection plays a crucial role in the development of cervical cancer. This sexually transmitted virus has over 200 types, with high-risk types such as HPV 16 and 18 responsible for approximately 70% of all cervical cancer cases worldwide. Persistent infection with these high-risk HPV types can lead to abnormal cell changes in the cervix, potentially progressing to precancerous lesions and, if left untreated, invasive cervical cancer.
While HPV infection is the main cause, other risk factors can increase the likelihood of developing cervical cancer:
- Suppressed immune response: Conditions that impair cell-mediated responses, such as HIV infection, renal transplantation, or immunosuppressive medications, increase the risk of HPV acquisition and progression.
- Long-term use of oral contraceptives: Studies suggest that taking oral contraceptives for more than five years may slightly elevate the risk of cervical cancer.
- Increasing parity: Having a higher number of full-term pregnancies is an independent risk factor for persistent HPV infection and cervical cancer development.

Lifestyle factors also play a role in cervical cancer risk. Smoking tobacco has been shown to increase the risk, with the risk escalating based on the number of cigarettes smoked per day. The suppression of local immune response and the mutagenic activity of tobacco components in cervical cells may contribute to HPV persistence and malignant changes.
Additionally, having multiple sexual partners or engaging in sexual activity at an early age can increase the chances of HPV infection, thereby elevating the risk of cervical cancer.
By understanding these risk factors, healthcare providers can identify women at higher risk and implement appropriate screening and preventive measures. Regular cervical cancer screening, HPV vaccination, and lifestyle modifications can significantly reduce the incidence and mortality associated with cervical cancer.
Diagnosis and Screening
Early detection of cervical cancer is crucial for successful treatment. Regular screening tests can help identify precancerous changes in the cervix before they develop into cancer. The two main screening tests for cervical cancer are the Pap smear and the HPV test.
The Pap smear, also known as a Pap test or cervical cytology, collects cells from the cervix to be examined under a microscope for abnormalities. This test is typically performed every three years for women between the ages of 21 and 65. If any abnormal cells are found, further testing may be necessary.
The HPV test checks for the presence of high-risk types of human papillomavirus, which are responsible for most cases of cervical cancer. This test can be done alone or in combination with a Pap smear (co-testing) for women aged 30 and above. If the HPV test is positive, additional follow-up tests may be recommended.

If screening tests show abnormal results, a colposcopy may be performed. During this procedure, a healthcare provider uses a special magnifying instrument called a colposcope to closely examine the cervix, vagina, and vulva for signs of disease. If suspicious areas are identified, a biopsy may be taken for further analysis.
A biopsy involves removing a small sample of tissue from the cervix for examination under a microscope. This procedure can help determine whether precancerous or cancerous cells are present and guide treatment decisions.
Regular screening and prompt follow-up of abnormal results are essential for the early detection and prevention of cervical cancer. Women should discuss the appropriate screening schedule with their healthcare provider based on their age, health history, and risk factors.
Conclusion
Cervical cancer remains a significant health concern for women worldwide, but advancements in screening, prevention, and treatment have a major impact on improving outcomes. Regular check-ups, HPV vaccination, and staying informed about risk factors are key steps to reduce the chances of developing this disease. By understanding the early signs and causes, women can take proactive measures to protect their health and seek timely medical attention when needed.
The fight against cervical cancer calls for ongoing efforts in research, education, and healthcare access. With continued progress in early detection methods and treatment options, there’s hope for further reducing the burden of this disease. Empowering women with knowledge and resources to manage their health is crucial to advance cervical cancer prevention and care. By working together, healthcare providers, researchers, and communities can make significant strides in tackling this challenging yet often preventable form of cancer.
