Cervical Cancer – Symptoms, causes, types, and treatment

Cervical cancer is a malignant tumor that occurs in the cells of the cervix, the lower part of the uterus that connects to the vagina. It is a significant health concern worldwide, especially in developing countries, but it is highly preventable and treatable if detected early. This blog post will cover the symptoms, causes, types, and treatment options for cervical cancer.

Symptoms of Cervical Cancer

Cervical cancer may not cause any noticeable symptoms in its early stages. As the disease progresses, several symptoms may appear:

1. Abnormal Vaginal Bleeding: This can include bleeding between menstrual periods, after sexual intercourse, or after menopause.
2. Unusual Vaginal Discharge: A watery, bloody discharge that may have a foul odor.
3. Pelvic Pain: Pain during intercourse or at other times.
4. Painful Urination: Discomfort or pain when urinating, which may indicate advanced stages of cervical cancer.

If any of these symptoms occur, it is crucial to see a healthcare provider for evaluation and diagnosis.

Causes of Cervical Cancer

Cervical cancer is primarily caused by persistent infection with certain types of human papillomavirus (HPV). HPV is a sexually transmitted infection that is very common and has many different types, some of which are high-risk and associated with cervical cancer.

Other factors that may contribute to the development of cervical cancer include:

1. Smoking: Tobacco use increases the risk of cervical and other cancers.
2. Weakened Immune System: Conditions like HIV/AIDS or the use of immunosuppressive medications can increase the risk of HPV infections leading to cervical cancer.
3. Multiple Sexual Partners: Having many sexual partners increases the risk of HPV infection.
4. Early Sexual Activity: Engaging in sexual activity at an early age increases the likelihood of acquiring HPV.

Types of Cervical Cancer

There are two main types of cervical cancer:

1. Squamous Cell Carcinoma: This type develops in the squamous cells that line the outer part of the cervix. It is the most common type of cervical cancer, accounting for about 70-90% of cases.
2. Adenocarcinoma: This type develops in the glandular cells that line the cervical canal. It is less common but has been increasing in incidence.

In rare cases, cervical cancer may have characteristics of both squamous cell carcinoma and adenocarcinoma, known as adenosquamous carcinoma.

Diagnosis of Cervical Cancer

Early detection is key to effectively treating cervical cancer. Regular screening tests can help detect precancerous conditions before they turn into cancer. The primary screening tests include:

1. Pap Test (Pap Smear): This test involves collecting cells from the cervix and examining them under a microscope to detect abnormalities.
2. HPV Test: This test detects the presence of high-risk HPV types in cervical cells.

If abnormal results are found, further diagnostic procedures, such as a colposcopy, biopsy, or endocervical curettage, may be performed to confirm the presence of cancerous or precancerous cells.

Stages of Cervical Cancer

Once diagnosed, cervical cancer is staged based on the extent of its spread. The stages range from I (confined to the cervix) to IV (spread to other parts of the body). The staging helps determine the appropriate treatment plan.

Treatment of Cervical Cancer

Treatment for cervical cancer depends on the stage of the disease, the patient’s overall health, and personal preferences. The main treatment options include:

1. Surgery:
   • Conization: Removing a cone-shaped piece of tissue from the cervix.
   • Hysterectomy: Removing the uterus and cervix. In some cases, the ovaries and fallopian tubes may also be removed (radical hysterectomy).
   • Trachelectomy: Removing the cervix and upper part of the vagina while preserving the uterus, allowing the possibility of future pregnancies.
2. Radiation Therapy:
   • External Beam Radiation Therapy (EBRT): Directing radiation at the pelvis from outside the body.
   • Brachytherapy: Placing a radioactive source directly inside or near the tumor.
3. Chemotherapy:
   • Using drugs to kill cancer cells. It is often combined with radiation therapy (chemoradiation) for advanced stages.
4. Targeted Therapy:
   • Using drugs that specifically target cancer cells with minimal damage to normal cells.
5. Immunotherapy:
   • Boosting the body’s immune system to fight cancer. Pembrolizumab is an example of an immunotherapy drug used for advanced cervical cancer.

Prevention of Cervical Cancer

Prevention strategies are highly effective in reducing the risk of cervical cancer:

1. HPV Vaccination: Vaccines like Gardasil and Cervarix protect against the most common high-risk HPV types.
2. Regular Screening: Routine Pap tests and HPV testing can detect precancerous changes early.
3. Safe Sexual Practices: Using condoms and limiting the number of sexual partners can reduce the risk of HPV infection.
4. Smoking Cessation: Avoiding tobacco use lowers the risk of cervical and other cancers.

Conclusion

Cervical cancer is a preventable and treatable disease, especially when detected early. Regular screening, HPV vaccination, and awareness of risk factors and symptoms are crucial steps in reducing the incidence and mortality associated with cervical cancer. If you experience any symptoms or fall into a high-risk category, consult with a healthcare provider for appropriate screening and preventive measures.
