Oral Cancer on the rise in the US- Are you being screened?

 

velscope%20cartoonAccording to the Centers for Disease Control and Prevention, cancers of the oropharynx (back of the throat, including the base of the tongue and tonsils) are usually caused by tobacco and alcohol, but recent studies show that about 72 percent of oropharyngeal cancers are caused by HPV.

“There has been significant change in the last decade. The HPV-associated oropharyngeal cancer has reached epidemic proportions,” Stenson warns.

The American Cancer Society estimates that 45,780 Americans will be diagnosed with cancer of the oral cavity and oropharynx in 2015.

If this trend continues, the number of cases of HPV-positive oropharyngeal cancer will surpass the number of cervical cancer cases.

Early detection is key

The HPV vaccine currently in use has been shown to decrease the incidence of cervical infections and cancer associated with the virus. While the same result is anticipated for HPV-associated head and neck cancer, the impact of vaccines on incidence of persistent oral HPV infection and/or HPV associated oropharyngeal cancer has not yet been investigated. Still, head and neck surgeons, medical oncologists and other researchers strongly advocate vaccination of both girls and boys to help prevent all HPV-associated cancers.

“For all individuals, the key is in early detection, as with any cancer,” Stenson observes.

In addition to being vaccinated, Stenson stresses the importance of regular visits to the dentist. “Dentists play a key role in detecting oral cancer,” she says. “You might not see a primary care physician even once a year, but most people see their dentist twice a year. Having regular dental visits can  help catch cancers early to help ensure the best outcome.”

The American Dental Association states that 60 percent of the U.S. population sees a dentist every year.

Oral cancer warning signs

The Oral Cancer Foundation presumes that cancer screenings of the existing patient population would yield tens of thousands of opportunities to catch oral cancer in its early stages.

Possible warning signs of oral cancer may include difficulty swallowing, pain when chewing, a white patch anywhere on the inside of your mouth, a lump or sore in the mouth or on the lip that does not heal. If you notice any of these symptoms, ask your dentist or doctor about it.

Treatment includes surgery for early or low-volume late stage lesions and radiation or chemoradiation for more advanced cancers.

“There is much that can be done for those who are diagnosed with head and neck cancer.  Since early detection and treatment is critical, it’s important to see your dentist regularly and to promptly see a medical professional if there are any warnings signs,” Stenson advises.

Is Vaping safer than Smoking?

Vaping

E-cigarettes emerged around 2004-2005 and have become increasingly popular as the “Healthier” alternative to smoking.  Although initial studies showed vaping had far less impact on health compared to smoking things are changing now as there is more long term studies coming out to the contrary.

In 2015, a letter from the New England Journal of Medicine expressed concern over formaldehyde, a toxic compound found in the vapors produced by e-cigarettes. While researchers are still studying its link to cancer, formaldehyde is known to cause irritation to the skin, eyes, nose, and throat.

Irfan Rahman, professor of Environmental Medicine at the University of Rochester, led the first study to examine the impact of e-cigarettes on oral health.

“We showed that when the vapors from an e-cigarette are burned, it causes cells to release inflammatory proteins, which in turn aggravate stress within cells, resulting in damage that could lead to various oral diseases,” he said.

This year, he was one of the authors of a studythat examined artificial flavors for inducing tissue damage and having a toxic effect on white blood cells, with the worst impact coming from cinnamon, vanilla, and buttery flavored e-juices. There are around 250 harmful chemicals found in traditional cigarettes while the number is significantly reduced in vaping. But the presence of nicotine still poses a threat (particularly risk of heart disease) in its concentrated, e-liquid form.

Another study using mice showed secondhand e-cigarette smoke could compromise the immune system. Thomas Sussan, lead author and an assistant scientist at the Bloomberg School, explained how the exposure to e-cigarette vapor “was followed by a bacterial or viral infection, the harmful effects of e-cigarette exposure became even more pronounced. The e-cigarette exposure inhibited the ability of mice to clear the bacteria from their lungs, and the viral infection led to increased weight loss and death indicative of an impaired immune response.”

In our office we believe more long term studies will show that vaping is not good for your oral care and can cause many problems down the road.
