Don't Ignore These Cervical Cancer Warning Signs

The American Cancer Society estimates nearly 14,000 new cases of cervical cancer were diagnosed in 2023, and just over 4,300 women died from the disease. These numbers are staggering, especially when cervical cancer is one of the most preventable cancers in women. Fortunately, the death rate from cervical cancer has decreased by more than 50% over the last 40 years due to increased use of the Pap test and human papillomavirus (HPV) vaccination. Abby Sexton, DO, UnityPoint Health, lists the signs of cervical cancer and why knowing them, along with regular screenings, can save your life.

Cervical Cancer Signs

Cervical cancer usually doesn’t have any symptoms until the cancer becomes more advanced. The most important risk factor for cervical cancer is infection with the types of HPV that lead to cancer. The following factors can increase your risk of becoming infected with HPV:

• Smoking
• Multiple sexual partners
• History of sexually transmitted infection (STI) 
• HIV
• Organ transplant
• Sexual intercourse before the age of 18
• A family history of cervical cancer
• Problems with the immune system

“Cervical cancer can occur at any age,” Dr. Sexton says. “It occurs more often after age 40, but it can happen at younger ages, too. It rarely occurs before age 21, which is why we recommend starting Pap smear screening at this age and not before.”

Once cervical cancer is more advanced, women may start to notice the following warning signs.

Abnormal Vaginal Bleeding

Dr. Sexton says the most common cervical cancer symptom is abnormal vaginal bleeding. Although women often think bleeding is normal, it's important to see your doctor if you experience:

• Bleeding between menstrual periods
• Heavier menstrual periods
• Longer menstrual periods
• Bleeding after sexual intercourse
• Bleeding after menopause
• Bleeding after a pelvic exam
• Bleeding resulting in anemia-causing fatigue, dizziness

Foul-Smelling Vaginal Discharge

As tumor cells die, they may create a foul-smelling vaginal discharge, which serves as another sign of cervical cancer. This continuous discharge may be pale, watery, brown or mixed with blood.

Pain During Sexual Intercourse

Women with advanced cervical cancer may experience pain during sexual intercourse because of tumor growth throughout tissues and reproductive organs.

Low Back, Pelvic or Appendix Pain

Low back pain or pelvic pain can be linked to problems with reproductive organs, such as the cervix. A sign of cervical cancer is pelvic pain, especially continuous pain. Pelvic pain near the appendix doesn't usually occur unless the cancer is in the advanced stages. There will typically be other cervical cancer red flags before pelvic pain occurs.

Leg Pain

As the cancer grows and becomes more advanced, it may start to press against nerves in the pelvic wall, resulting in leg pain and sometimes swelling. While swelling could be a symptom of a number of medical problems, if accompanied by leg pain, this could be a warning sign of cervical cancer.

Loss of Appetite or Unexplained Weight Loss

As with many other cancers, a sign of cervical cancer is unexplained weight loss or loss of appetite. Sometimes, regardless of how much food is consumed, weight loss continues to be a problem for women with cervical cancer.

Prevention & Early Detection

Cervical cancer screening in the form of Pap tests (Pap smears) looks for abnormal cells or changes in the cells of the cervix. Regular Pap smears are the best method for both prevention of cervical cancer and for catching cervical cancer in the earliest stages, which is why they're strongly recommended.

“Because of effective screenings, cervical cancer is seen less in the United States,” says Dr. Sexton. 

HPV (Human papillomavirus) Vaccine

The most common cause of cervical cancer is the human papillomavirus (HPV), and Dr. Sexton says receiving the HPV vaccine is the best way to prevent cervical cancer. It’s important both males and females receive all doses of the HPV vaccine. The Centers for Disease Control and Prevention recommends the following HPV vaccine schedule:

• All kids ages 9-14 should get the HPV vaccine
• A two-dose series is given for patients under the age of 14; an initial dose followed by a second dose in 6-12 months
• Patients between the ages 15-45, as well as immunocompromised patients, will receive a three-dose series: an initial dose followed by a second dose in two months and a third dose six months later
• If children and teenagers don’t receive the vaccine when they’re younger, it's recommended both men and women get vaccinated until the age of 45
• Vaccination works best when it’s done before a person becomes sexually active and exposed to HPV. However, HPV vaccination can still reduce the risk of getting HPV for people who are already sexually active
• If a person has never received the vaccination and already has a diagnosis of HPV, it’s recommended they get vaccinated to help prevent getting a new infection in the future.

Does HPV Go Away?

The body uses its immune system to help get rid of HPV, and the infection usually goes away by itself. In a small number of cases, HPV does not go away. The longer HPV is present, and the older you are, the greater the risk the virus will damage the cervical cells.

In addition to early screenings and the HPV vaccine, Dr. Sexton offers these steps to reduce your risk of cervical cancer:

• Practice safe sex by consistently using condoms, especially if you’ve had, or plan to have, multiple partners
• Avoid sexually transmitted infections (STIs) by discussing sexual health history with your partner
• Stop smoking

“Carcinogens associated with smoking can lead to early progression of cervical cancer, and other cancers, too. Smoking causes DNA damage that increases the likelihood of cancerous cell changes and reduces the ability of the immune system to clear HPV from the body. That’s why it’s so important to seek help and break the habit as soon as possible,” Dr. Sexton says.

If cervical cancer is diagnosed, more tests, like blood work and scans of the abdomen and pelvis, will allow your cancer team to form a treatment plan. Treatment is very effective if caught in the early stages, with higher survival rates at five years (more than 90 percent) after the cancer is diagnosed.

Talk to your doctor about a cervical cancer screening schedule and ensuring you, and any children you may have, are vaccinated against HPV.
