Cervical - Cancer Science

What is Cervical Cancer?

Cervical cancer occurs in the cells of the cervix, the lower part of the uterus that connects to the vagina. It is primarily caused by persistent infection with high-risk strains of the Human Papillomavirus (HPV). Cervical cancer is one of the most preventable types of cancer, thanks to effective screening tests and the availability of the HPV vaccine.

What are the Risk Factors?

Several factors can increase the risk of developing cervical cancer, including:
HPV infection: The most significant risk factor.
Smoking: Doubles the risk of cervical cancer.
Immunosuppression: Conditions like HIV/AIDS can increase risk.
Long-term use of oral contraceptives: This can slightly increase the risk.
Multiple full-term pregnancies: More than three can elevate risk.

How is Cervical Cancer Diagnosed?

Diagnosis usually involves a combination of screening tests and diagnostic procedures, including:
Pap smear test: Detects precancerous or cancerous cells in the cervix.
HPV DNA test: Identifies high-risk HPV strains in cervical cells.
Colposcopy: A closer examination of the cervix using a special instrument.
Biopsy: Removal of a small sample of tissue for laboratory examination.

What are the Symptoms?

Early-stage cervical cancer generally has no symptoms. As the disease progresses, symptoms may include:
Abnormal vaginal bleeding: Including bleeding after intercourse, between periods, or after menopause.
Unusual vaginal discharge: May be watery, bloody, or have a foul odor.
Pelvic pain: Especially during intercourse.

What are the Treatment Options?

Treatment for cervical cancer depends on various factors, including the stage of the cancer, the size of the tumor, and the patient's overall health. Common treatments include:
Surgery: To remove cancerous tissue, including hysterectomy in advanced cases.
Radiation therapy: Often combined with chemotherapy for advanced stages.
Chemotherapy: Uses drugs to kill cancer cells, often used in combination with radiation.
Targeted therapy: Drugs or other substances specifically attack cancer cells with minimal damage to normal cells.

Can Cervical Cancer Be Prevented?

Prevention strategies are very effective and include:
HPV vaccination: Recommended for boys and girls starting at ages 11-12.
Regular screening: Pap smears and HPV tests help detect precancerous conditions early.
Safe sex practices: Using condoms and limiting the number of sexual partners.
Quitting smoking: Reduces the risk of cervical and other cancers.

What is the Prognosis?

The prognosis for cervical cancer varies significantly based on the stage at which it is diagnosed. Early-stage cervical cancer has a very high 5-year survival rate, often exceeding 90%. However, once the cancer has spread beyond the cervix, the survival rates drop significantly. Early detection through regular screening is crucial for improving outcomes.
