Cervical Cancer

What is Cervical Cancer?
Cervical cancer is a type of cancer that develops in the cells of the cervix—the lower, narrow cylinder of the uterus that opens into the vagina.

The Prevention Advantage: Cervical cancer is one of the most preventable and highly treatable forms of cancer, provided it is detected early. This is because we have identified the primary cause of nearly all cases: persistent infection with high-risk strains of the Human Papillomavirus (HPV).

Myth: "Only people with many sexual partners get HPV."
Fact: HPV is so incredibly common that nearly all sexually active individuals will contract at least one type of HPV at some point in their lives. In most people, the immune system successfully clears the virus within two years. Cervical cancer only occurs when high-risk strains of the virus survive for decades, slowly and silently mutating the cervical cells into a precancerous state.

Signs & Symptoms

In its earliest, most treatable stages, cervical cancer usually produces no physical symptoms at all. This makes regular clinical screening a vital necessity. As the cancer grows or spreads to nearby tissues, symptoms may include:

• Abnormal Vaginal Bleeding: Bleeding after sexual intercourse, bleeding between regular periods, heavier-than-usual periods, or any vaginal bleeding after menopause.
• Unusual Discharge: A persistent, watery, or bloody vaginal discharge that may be heavy and have a distinct foul odor.
• Pelvic Pain: Unexplained pain during sexual intercourse or persistent, deep pelvic aching.

When to See a Gynecologist

You should schedule an appointment with your gynecologist if you experience any changes in your menstrual cycle, unusual discharge, or pain during intimacy. While these symptoms can be caused by infections or benign conditions, they must be clinically ruled out. Furthermore, if you are overdue for a Pap test or HPV screening, do not wait for symptoms to appear—screening is designed to find problems before you feel them.

⚠️ RED FLAG: ADVANCED SIGNS
Seek medical attention if you experience severe, persistent pain in your lower back or pelvis that radiates down the legs, accompanied by swelling in one leg, difficulty urinating, or unintended weight loss. These can indicate that the cancer has spread beyond the cervix.

Screening & Prevention: The Ultimate Defense

Because cervical cancer takes years to develop from precancerous cells, standard screening tests can literally stop the disease before it begins.

The Tool	How it Works
The Pap Test	A clinician collects cells from the cervix to be examined under a microscope for precancerous changes (dysplasia). Regular Pap tests reduce cervical cancer deaths by over 80%.
The HPV DNA Test	Looks specifically for the genetic material (DNA) of high-risk HPV strains (like 16 and 18) that are known to cause the majority of cervical cancers.
The HPV Vaccine	Protects against the strains responsible for 90% of cervical cancers. It is most effective when given at ages 11-12, but is now FDA-approved for adults up to age 45.

Other Risk Factors

While HPV is the necessary cause, other factors can impair the body's ability to clear the virus, allowing it to progress toward cancer:

• Smoking: Tobacco by-products are found in the cervical mucus of smokers. These chemicals damage the DNA of cervical cells and weaken the immune system's local response to HPV.
• Immune Suppression: Living with HIV or taking immunosuppressant medications makes it significantly harder for the body to clear an HPV infection.
• Long-Term Use of Oral Contraceptives: Using birth control pills for 5 or more years is associated with a slight increase in risk, which gradually returns to normal after the pills are stopped.

Diagnosis & Treatment

If a screening test is abnormal, your doctor will perform a Colposcopy. This involves using a magnifying instrument to look at the cervix and taking a biopsy to confirm the presence of cancer or precancerous cells.

Treating Pre-Cancers

Precancerous cells (CIN) can be removed before they ever become invasive. Procedures include Cryotherapy (freezing), Laser Therapy, or a LEEP procedure, which uses a thin, electrified wire loop to precisely remove abnormal tissue.

Treating Invasive Cervical Cancer

• Surgery: Early-stage cancer may be treated with a hysterectomy. For younger women wishing to preserve fertility, a Radical Trachelectomy (removing the cervix and surrounding tissue while leaving the uterus intact) may be an option.
• Radiation & Chemotherapy: Often used together (chemoradiation) to treat larger tumors. Brachytherapy involves placing a radioactive source directly inside the vagina near the tumor for targeted treatment.
• Immunotherapy: Uses medications to help your own immune system recognize and destroy cancer cells, typically used for advanced or recurrent cases.

Frequently Asked Questions (FAQs)

If I had the HPV vaccine, do I still need Pap tests?

Yes. While the vaccine provides excellent protection against the most common cancer-causing strains, it does not cover every possible high-risk strain. Regular screening remains necessary for all women, regardless of vaccination status.

Can cervical cancer be cured?

Yes. When detected at the "carcinoma in situ" or early invasive stages, the survival rate is very high (over 90%). Even in more advanced stages, modern combinations of surgery, radiation, and immunotherapy are highly effective at controlling the disease.
