Risk HPV 24 Mar

Are You at Risk for HPV?

The chances are pretty good that you—or someone you know—is infected with the human papillomavirus (HPV). It’s the most common sexually transmitted infection in the United States, currently affecting a whopping 79 million Americans, most of them in their late teens and early 20s.

In some cases, HPV infection can prove deadly, leading to an estimated 33,700 cases of cancer each year in both men and women.

Here’s what you need to know to protect yourself and your loved ones.

Understanding the virus

Rather than one specific virus, HPV is actually a group of more than 200 related viruses. More than 40 of them can be spread through direct sexual contact, whether vaginal, anal or oral sex. Of these types of HPV, 13 strains are can lead to certain forms of cancer, including cancers of the cervix, vagina, penis and anus as well as cancers of the head and neck. As a result, these viruses are considered high-risk strains. (Keep in mind: the HPV strains that cause skin warts around the genitals and anus typically don’t go on to cause cancer.)

Before you panic, keep in mind that HPV is so common that 80 percent of people will get an HPV infection during their lifetime, according to the Centers for Disease Control and Prevention (CDC). About ninety percent of the time, HPV goes away within two years on its own.

But in some cases, it can linger and lead to cancer:

Cervical cancer: Virtually all cases of this disease are caused by the HPV virus, says Nadine Zekam, MD, an OBGYN at Medical City Arlington in Arlington, Texas. Each year, nearly 13,000 women are diagnosed with cervical cancer and more than 4,000 die from the disease, according to the CDC.

Throat cancer: In the U.S., it’s estimated that 3,400 women and 14,800 men are newly diagnosed with HPV-associated oropharyngeal cancers each year in the United States, the CDC reports.

Anal cancer: Every year in the United States, 5,900 people are diagnosed with anal cancer.

Penile, vulvar and vaginal cancer: Some 3,300 women are diagnosed with vulvar and vaginal cancers annually in the United States while 800 men are diagnosed with penile cancer each year.

Who’s at risk for HPV?
You’re at increased risk for HPV infection if you:

Have multiple sexual partners. The more partners you have, the more likely you are to be exposed to HPV. But even if you’re monogamous, you may be more susceptible if your partner has multiple sex partners.

Start having sex at a young age. “The earlier you become sexually active, the more likely you are to come into contact with HPV,” explains Dr. Zekam.

Smoke. While smoking itself doesn’t raise risk for HPV, it appears to make it more likely that it will progress to cancer, says Zekam. Women who smoke, for example, are about twice as likely to develop cervical cancer as non-smokers, possibly because compounds in tobacco smoke damage the DNA of cervix cells. Smoking also makes it harder for the immune system to fight off HPV infections.

Signs to watch out for

If you have the type of HPV that causes genital warts, you may see small cauliflower-like bumps on your vulva if you’re a woman or on your penis or scrotum if you’re a man. Warts can also crop up near your buttocks or in your throat if you’ve had oral sex. They don’t usually hurt, but they can itch.

Your healthcare provider can prescribe medicine to boost your immune system to help your body fight off infection as well as topical treatments to prevent wart cells from growing. Your doctor can also remove growths by cutting them off, freezing them off—a procedure called cryotherapy—or destroying them with electric currents or lasers.

If you have the type of HPV that can cause cancer, there aren’t any symptoms until you begin to develop a disease such as throat or cervical cancer, says Zekam. That’s why taking steps to protect yourself and avoid getting HPV in the first place are so important. Here’s how:

Get vaccinated

It’s recommended that all boys and girls receive the two-dose vaccine by age 11 to 12.

“Ideally, you want to give the vaccine to someone a few years before they become sexually active, so that they’re protected,” explains Zekam.

Women and men (not previously HPV vaccinated) can also receive the vaccine up to age 26, and in some cases, as old as 45. If you’re in this age group, ask your doctor what is right for you.

The HPV vaccine protects against nine strains of the virus, including seven of the most common cancer-causing types as well as the two responsible for genital warts. It could prevent more than 90 percent of related cancers from ever developing and not only protect against infections that cause six types of cancer but also help people avoid uncomfortable testing and treatment, which in some cases, can affect fertility, the CDC advises.

Get screened

All women between the ages of 21 and 65 should be screened for cervical cancer. Women in their 20s should get a Pap smear every three years. “We don’t do HPV testing in this age group,” Zekam explains. This is because while HPV infection is common in this age group, about 90 percent of the time the virus disappears on its own within two years. But if a young woman has a positive HPV test, it will require more follow-up testing and procedures that can be stressful and that may ultimately result in impaired fertility.

Women over the age of 30 have two options: either a Pap smear every three years or screening with a combination of both a Pap smear and HPV testing every five. You can stop screening after age 65 if you don’t have a history of cervical cancer and if you’ve had either three negative Pap tests in a row or two negative combination results within the previous ten years with the most recent one having been performed within the previous five years, according to the American College of Obstetricians and Gynecologists.

But while doctors can screen for cervical cancer, keep in mind that there aren’t screening tests for the other 20,000 cases of cancers caused by HPV infections each year, according to the CDC. That’s why it’s so important to get the vaccine if you can.

Get condoms—and use them. The only way to protect yourself 100 percent against HPV is to avoid sex completely. But that may not be a realistic option for most people.

If you’re not in a mutually monogamous relationship, your next best bet is to always use condoms, even if you’re on other methods of birth control such as an IUD or oral contraceptives. Just keep in mind that since HPV can infect areas not covered by condoms, they don’t offer complete protection.
