Why?

Why Should You Take Advantage of These Screenings?
Like other cancers, it's easier to treat oral cancer if it's caught in the early stages. In fact, the five-year overall survival rate in stage 1 and 2 cancers of this type is usually 70 to 90 percent. However, these percentages decrease if cancer is allowed to grow.
In earlier stages, cancer cells haven't spread to lymph nodes or the rest of the body, so it's easier to treat. If you have cancer screenings done at your regular cleaning appointments, you'll have a better chance of successfully catching and treating the issue.

Who is at risk?

Who's at Risk for Oral Cancer?
You should ask your dentist about the frequency of screenings, as some people are more at risk for the cancer than others. Some risk factors include:
-A history of sun exposure — especially if you are fair skinned-Older age-Poor oral hygiene-A previous HPV diagnosis-Poor nutrition-Tobacco use of any kind-Marijuana use-A weak immune system

What are the Signs and Symptoms

Besides the risk factors, you should be aware of the signs and symptoms of cancer. Some of these include:
Thickened tissue or lumps inside the mouth
-A sore throat or feeling like you need to clear your throat continually-Difficulty chewing or swallowing-Halitosis-White or red patches on your lips or inside your mouth-Weight loss-Jaw pain
As you can see, since some of these symptoms can mimic other issues, it's best to visit a dentist to get a correct diagnosis and rule out cancer. For instance, jaw pain doesn't necessarily indicate oral cancer; it could be indicative of bruxism or a deep cavity.

What Is an Oral Cancer Screening Like?
An oral cancer screening is a quick, non-invasive procedure. With gloved hands and a tongue depressor, your dentist will examine inside your mouth and under your tongue to check for any patches or sores. Your dentist will also feel for any lumps underneath the skin that may not be apparent to the naked eye.
