Causes and Symptoms of Oral Cancer

Monday - 04.29.2019

Did you know men are two times more likely to be diagnosed with oral cancer than women and the fastest growing segment of the oral cancer population are non-smokers younger than 50?

Early detection is key. Dental associations are urging the public to get regular oral cancer screenings. The good news is oral cancer screenings can be done by your Gentech dentists during your regular dental check-up.

Every hour of every day someone dies of oral cancer. This year, an estimated 51,550 new cases of oral cancer, cancer that develops in any part of the mouth and upper throat, will be diagnosed. Forty-three percent of people diagnosed will not survive longer than five years and survivors are likely to suffer from severe facial disfigurement, difficulty eating and trouble speaking. Because diagnosis tends to be too late in the cancer development stage the death rate of oral cancer is still particularly high.


“At Gentech Dentist, we evaluate not only your dental needs, but your overall health;

this why all of our patients receive regular oral cancer evaluations.

You can be assured that you will be treated with the

same quality care we ourselves would expect to receive.”

 Dr. Watanabe, Gentech Dentist Vancouver, WA


This April, we celebrate Oral Cancer Awareness Month as an effort to create awareness around this devastating disease. By participating in regular dental visits and oral cancer screenings your chances of early detection are dramatically increased. 

Be mindful of your symptoms

Oral cancer can occur on the lips, gums, tongue, inner cheeks, and the roof or floor of the mouth (under the tongue). Signs and symptoms may include:

  • A lip or mouth sore that does not heal within 14 days
  • A white, red, or black patch on the inside of your mouth
  • Any abnormality that bleeds when touched
  • A growth, hard lump, or thickening inside your mouth (usually on the side of the tongue)
  • Mouth pain
  • Ear pain
  • Difficulty or painful swallowing
  • A painless, firm, fixated lump felt on the outside of the neck that has been there for at least two weeks.

See your doctor immediately if any of the above symptoms persist and are bothersome for over two weeks. Your doctor will likely investigate other more common causes for your signs and symptoms first, such as an infection, as well as conducting an oral cancer screening.

Oral cancer can also be linked to the HPV virus. The same types of HPV that infect the genital areas can infect the mouth and throat – called oral HPV. HPV can cause normal cells to become abnormal. Cancer-causing types of oral HPV can cause cancers of the larynx (voice box), throat, lips, mouth, nose, and salivary glands. Tobacco, alcohol and infection with HPV increase the risk of being diagnosed with oral, neck, or head cancers. Oral HPV is three times more likely in men than women.

Signs and symptoms of HPV-caused oral cancers may persist longer than two to three weeks and may include one or more of the following:

  • Hoarseness or a sore throat that does not resolve
  • A painless, firm, fixated lump felt from the outside or your neck
  • Constant coughing
  • Difficulty swallowing and/or a sensation of food getting caught the throat
  • A persistent ear ache on one side that persists for more than a few days
  • Enlarged lymph nodes
  • Unexplained weight loss

Some people may not experience any signs or symptoms. Call your Gentech dentist right away with any immediate concerns.

Lower your risk.

There is no “at-home test” for oral cancer, so your best bet to lower your risk of being diagnosed is to make educated and healthy decisions. Though, no method is 100% guaranteed to keep you cancer free. Here are some ways to lower your risk:

  • Stop smoking or don’t start – Using tobacco, whether smoked or chewed, exposes the cells in your mouth to dangerous cancer-causing chemicals. This includes cigarettes, pipes, hooka, snuff, chewing tobacco, and cigars among other things.
  • Limit alcohol consumption – Excessive alcohol use can irritate the cells in your mouth making them vulnerable to oral cancer. If you choose to drink alcohol, drink in moderation. For a healthy adult drinking in moderation means two drinks a day for men under 65years and one drink a day for men over 65years and women of all ages.
  • Safe sex practices – To lower your risk of contracting oral HPV and the oral cancers associated with it, limit your chances of contracting all HPV by practicing safe sex. Always use condoms, dental dams, and limit the amount of sexual partners. In addition, if you are sexually active receiving regular STI and annual Pap testing is recommended.
  • Get your HPV vaccine – The HPV vaccine can lower your chances of contracting HPV and developing HPV related oral cancers – specifically oropharyngeal cancers. Though studies have not been done to specifically prove that the HPV vaccine prevents oropharyngeal cancers, because it prevents other infections associated with HPV it may be beneficial in preventing oral HPV-related cancers. The CDC recommends that 11-12 year old boys and girls should be vaccinated to protect against cancers caused by HPV. If you or your child was not vaccinated at 11 or 12 years of age, it is also recommended that girls through age 26 and boys through age 21 get vaccinated. For more information about the HPV vaccine and how it relates to your overall health, contact your primary care doctor.
  • Protect your lips – Excessive sun exposure to your lips may be a factor in developing oral cancer. Stay out of the sun and in shaded areas whenever possible, wear broad-brimmed hats that shade your entire face, including your mouth, and apply a chapstick or other lip products that contain sunscreen with an SPF of 25 for extra protection against the sun’s harmful UV rays.
  • Visit your dentist regularly – Gentech Dentists, as part of your routine dental exams, inspect your entire mouth for abnormal areas that may indicate precancerous changes, oral cancer, or other oral diseases.
