3What is Oral Cancer?Group of neoplasms (abnormal tissue growth) that involve of the lip and oral cavity which can be benign (not cancer) or malignant (cancer).Oral Cavity:buccal mucosa, gingiva, front or under tongue, hard palate, and the retromolor region
5What is Oral-pharyngeal Cancers? Cancers that arise from the back of the throat.Base of tongue, palatine tonsils, soft palate, and posterior pharyngeal wall90 % are squamous cell carcinomaRobert Hermans Cancer Imaging. 2005; 5(Spec No A): S52–S57.

6Head and Neck Cancer Statistics 41,000 people diagnosed yearly in the U.S.Approximately 12,000 deaths per year
7Oral Cancer: Changes in Patterns Past risk factors:Tobacco, alcohol and over 40 yrs of ageToday risk factors:HPV –independent risk factor with the highest incidence among those yrs of age
8Oral Cancer: Changes in Patterns 41,000 HAVE HEAD AND NECK CANCERS EACH YEAR: 50-65% ARE HPV RELATEDHPV related incidence has doubled since 1974(National Cancer Institute)
9At RiskNewer demographics emerging in addition to traditional demographicsAge (younger)Non-smokersNo excessive alcohol use
10Oral Cancer FactsOral cancer is cancer that arises in the head or neck region, including the nasal cavity, sinuses, lips, mouth, thyroid glands, salivary glands, throat or larynx (voice box). According to the American Cancer Society, an estimated 52,610 new cases of cancer of the oral cavity and throat, and an estimated 11,500 deaths from these cancers, are expected in 2012.
11Signs and SymptomsMost oral cancers arise on the lips, tongue or the floor of the mouth.They also may occur inside your cheeks, on your gums or on the roof of your mouth.Other head and neck cancers arise from the throat.
12Some Signs and Symptoms include: A sore in your mouth that doesn't heal or that increases in sizePersistent pain in your mouthLumps or white or red patches inside your mouthDifficulty chewing or swallowing or moving your tongueSoreness in your throat or feeling that something is caught in your throatChanges in your voiceA lump in your neck
13Risk FactorsTobacco (including smokeless tobacco) and alcohol use are the most important risk factors for oral, head and neck cancers, particularly those of the tongue, mouth, throat and voice box.Eighty-five percent of head and neck cancers are linked to tobacco use.People who use both tobacco and alcohol are at greater risk for developing these cancers than people who use either tobacco or alcohol alone. (Source: National Cancer Institute).Anyone can develop thyroid cancers, although a family history or exposure to radiation is often a factor.Salivary gland cancers do not seem to be associated with any particular cause.
14Human Papillomavirus (HPV) and Oral Cancer Researchers have attributed the increase of head and neck cancer incidence in young adults, a group traditionally at low risk, to the human-papillomavirus (HPV), a cancer-causing virus that can be transmitted through oral sex.
15Human Papillomavirus (HPV) and Oral Cancer Many studies support that oropharyngeal cancers -- those affecting the tonsils, back of the mouth (throat) and base of the tongue -- have been on the rise since the mid-1980s, and currently percent of these cases are caused by HPV infection.Many studies show that patients with HPV-positive oropharyngeal cancers are more responsive to treatment and have better survival rates than HPV-negative patients.
18Technology of OC Adjunct Devices Emits a safe blue light into the oral cavity, which excites natural fluorophores from the surface of the epithelium through to the basement membrane (where premalignant changes typically begin) and into the stroma beneath, causing it to fluoresce.The filter makes fluorescence visualization possible, by blocking reflected blue light, and by enhancing the contrast between normal and abnormal tissue.
24What is OHANCAW?Oral, Head and Neck Cancer Awareness Week® (OHANCAW®) is a weeklong series of events that aim to educate the public about these potentially life-threatening but eminently treatable cancers and to promote prevention, screening and early detection.OHANCAW is highlighted by the free screenings and related activities held at participating medical centers across the country.The screenings are quick, painless, and designed to advance early diagnosis, which can lead to better outcomes.OHANCAW is sponsored by the Head and Neck Cancer Alliance (HNCA).

26When is OHANCAW?The primary focus of our media efforts will be directed toward awareness activities occurring during this week, but HNCA is encouraging all supporters to pick a week during the year that works best for their group to host a free screening event. For more information, go to or call
27Conclusion Dental Public Health Through intra/extra oral examinations is criticalOral Cancer ScreeningsAll lesions must be differentially diagnosedPersistent lesions must be biopsiedOral Cancer Awareness campaigns to include tobacco cessation, alcohol use, sexual practice are critical
