Patient Information
As the only specialized ENT laboratory in the U.S., Sentry Laboratories provides your otolaryngologist with the most accurate results to enhance your care.
The Importance of an ENT Screening Exam:
ENTs routinely screen all of their patients by performing a careful examination of the Head and Neck. During the exam, your ENT may notice a white or red area in your mouth or throat, an ulcer or a small bump. Most of the time, these common spots are entirely harmless and cause no problems. Many people have them. Sometimes, even though these common spots do not look particularly abnormal to your ENT, they may contain abnormal cells. And if not treated, these cells, although not dangerous now, could potentially turn into cancer. That's why your ENT will take a sample of the area and send it for analysis to Sentry Laboratories, the only ENT specialty laboratory in the U.S., to make sure it's not dangerous. The sample is easily obtained by your ENT as an office procedure.
Who is at Risk:
Although all adults are routinely screened by ENTs, those who use tobacco and alcohol, and chronic acid reflux (heartburn) sufferers are at increased risk. Recent studies show that there has been an increase in cases in women, young people under 40, and non-smokers. Sometimes, Head and Neck cancers even develop in those with no risk factors. That's why it's important to see your ENT who will look for common white or red areas, even if you have no symptoms such as pain or a sore that does not heal. And if Sentry Laboratories identifies abnormal cells, your ENT will treat it, potentially preventing cancer from ever developing.
