Preventing cervical cancer

  • Cervical cancer is one of the most preventable cancers, but it claims the lives of about 4,000 people a year.

  • Cervical cancer is caused by the human papilloma virus, which will likely affect nearly everyone who’s sexually active at some point. Most infections go away on their own, but those that linger can lead to cancer.

  • January is Cervical Health Awareness Month. A gynecological oncologist at Swedish outlines screening guidelines and explains why early detection is so important.

Screening and vaccination have made cervical cancer one of the most preventable forms of cancer, and yet, research indicates the number of people diagnosed with late-stage cervical cancer is increasing. In fact, about 11,500 new cases of cervical cancer are diagnosed every year, and roughly 4,000 people die from the disease, according to the U.S. Centers for Disease Control and Prevention. And some of those deaths could have been prevented.

Cervical cancer is caused by the human papilloma virus (HPV). Nearly everyone who’s sexually active will become infected with HPV at some point. However, most HPV infections go away on their own once your immune system kicks in and gets the infection under control. When the infection lingers, it can cause changes in cervical cells that could develop into cervical cancer.

January is Cervical Health Awareness Month. We talked to Joshua Z. Press, M.D., MSc, a gynecologic oncologist at Swedish, about cervical cancer and the ways it can be prevented. Here’s what he shared.

Vaccinate early, screen regularly

Protecting yourself against cervical cancer is relatively straightforward, according to Dr. Press. “Nothing beats vaccination, screening and early detection,” he explains. “Screening is the most important step. Most patients that I see who come in with cervical cancer have not done their screening, and that’s disappointing. For the screening guidelines to work, you have to follow them.”

Screening guidelines

The American Cancer Society updated its cervical cancer screening guidelines in 2020. Changes to the recommendations included raising the age from 21 to 25 to start screening and using an HPV test as a primary screening tool.

There are two main types of cervical cancer screening:

  • The HPV test looks for the presence of the human papillomavirus.
  • The Pap test looks for precancers, or cell changes on the cervix, that have the potential to become cancer if left untreated.

Recommendations now state:

  • Screenings should begin at age 25.
  • An HPV test is the recommended screening method.
  • People with a cervix should be screened every five years.
  • People older than 65 do not need a cervical cancer screening if their prior test results were normal.

“Cervical cancer is one type of cancer that has good, effective screening,” says Dr. Press. “Even if you’ve been vaccinated against HPV, you should still get screened.”

HPV vaccine

The HPV vaccine is a safe, effective way to prevent cervical cancer. The vaccine offers the most protection when given to someone who’s not yet sexually active, and therefore has not been exposed to HPV. It may be given starting at age 9. It is administered in a series of either two or three doses, depending on your age.

The CDC recommends:

  • Children ages 11 – 12 years should get two doses of HPV vaccine, given six to 12 months apart.
  • Children who start the HPV vaccine series on or after they turn 15 need three doses of HPV vaccine, given over a six-month period.
  • Everyone through age 26 should get an HPV vaccine if they were not vaccinated when they were younger.
  • Some adults aged 27 through 45 who have not been vaccinated might choose to get an HPV vaccine after speaking with their doctor.

Advances in treatment

Treatment for cervical cancer has improved significantly over the past several years, says Dr. Press.

“For appropriate early-stage disease, we have been able to reduce how aggressive we are with surgery. We can perform a less morbid ‘simple’ type of hysterectomy instead of a radical hysterectomy, which has more risk of complications,” he explains.

“We have also implemented a more precise method to evaluate for spread of cancer cells outside the cervix, called sentinel lymph node dissection. Instead of taking out a large number of randomly selected lymph nodes, we use a fluorescent marker to pinpoint the lymph nodes that actually originate from cervical lymph channels. This marker directs us to the one or two lymph nodes that drain from the cervix, and thus are at risk of containing metastatic cancer cells,” adds Dr. Press.  

According to Dr. Press, these new techniques reduce the risks associated with surgery, and allow for quicker post-operative recovery.   However, to benefit from these less aggressive surgical techniques, the cancers must be detected in early stage, which highlights the importance of screening and early detection.

Pairing traditional chemotherapy with newer targeted therapies has improved the results for people with more advanced, later-stage cervical cancers. Drugs called angiogenesis blockers inhibit the formation of new blood vessels which prevents tumors from forming or growing larger. Immunotherapy works with your body’s immune system to boost its ability to detect and destroy cancer cells.

“Some of the best responses we’ve seen in advanced cervical cancer are from a combination of traditional chemotherapy combined with both targeted angiogenesis inhibitors and immunotherapy,” says Dr. Press. “With that combination, we’ve been able to get some patients with metastatic disease into remission in a way that we just didn't have in the past.”
