NEW HPV CANCER CONCERNS
DERRY TOWNSHIP, Pa.-The Human Papillomavirus, or HPV has long been
associated with cervical cancer, a cancer that strikes 12 thousand women a
year. Now, there's new concern, as researchers begin to link HPV to head
and neck cancers.
Why should you listen? Because HPV is the most common sexually transmitted
disease. Doctors say nearly every single person who's been sexually active
has been exposed to the virus at some point in their lives.
For years, doctors have been able to catch the cancer causing virus by
identifying abnormal pap smears during annual gynecological exams. Now that
it's being linked to head and neck cancers, doctors are pushing to get the
word out, because there are no routine screenings for those types of cancers
. "This is new, this is not something that was there fifteen years ago in
these numbers. Everyone in my field is rushing to figure out why this is
happening, and what they can do to stop it," says Dr. David Goldenberg, the
Director of head and neck surgery and Penn State Hershey Medical Center. He
adds HPV is responsible for more than 60 percent of cases of oropharyngeal
cancers diagnosed at Hershey Medical Center.
"And we're seeing younger people with head and neck cancer when it's
typically an older man's disease." Dr. Goldenberg says it's also typically
much more prevalent in people who use both alcohol and tobacco. That
remains the case, but combine that with someone who has been exposed to HPV
and their risks are far greater.
WHAT IS OROPHARYNGEAL CANCER?
So what is oropharyngeal cancer? They are the cancers in the areas of the
soft palate, the side and back walls of the throat, the tonsils, and the
root or the back of the tongue.
The good news, says Dr. Goldenberg, is that most patients who have an HPV
induced oropharyngeal cancer fare better than those who have a smoking
induced oropharyngeal cancer. "They do better, their prognosis is better,"
he adds.
The key, as in all cancers, is catching it early. Many people don't know
they have it until it's already turned into a killer.
ACTOR MICHAEL DOUGLASS JOINS THE FIGHT
Actor Michael Douglas was diagnosed with stage 4 squamous cell oral cancer
in 2010, and it was associated with HPV. After a long and difficult battle,
he's now in remission, and working with the Oral Cancer Foundation to get
the word out about the rapid rise in cases.
In the public service announcement Michael Douglas says, "Oral cancers are
increasing in the U.S. and as in my own case, most people know little about
them...thankfully in a fast, inexpensive, and painless visual and tactile
screening, a medical or dental professional can often identify early stage
disease." He urges everyone to ask for a screening next time they go to the
dentist or doctor, because again he says, often the cancer is visible to the
eye.
SYMPTOMS OF OROPHARYNGEAL CANCER
Dr. Goldenberg says some of the cancer can be seen by looking into the back
of someone's mouth. Masses that aren't typically there, a tonsil that
becomes enlarged or white in color, a bump on the back of the tongue are all
things that should be pointed out to a healthcare professional. Other
sypmtoms include a sore throat that doesn't go away over time, problems
swallowing, experiencing a feeling of something stuck in the throat, ear
aches, and painless lumps in the neck.
HOW PREVALENT IS THE PROBLEM?
The Center for Disease Control and Prevention estimates each year in the U.S
., about 9-thousand people are diagnosed with head and neck cancers caused
by HPV. Dr. Goldenberg says it's clear not everyone exposed to HPV is at
risk of this type of cancer, but stresses this is something that should be
on everyones' radar. "Almost anyone who's had any sexual activity has been
exposed to at least one strain or more of the HPV virus because it's out
there," he says.
