Protecting Your Good Health

OralCDx, an additional test helps doctors reliably find precancer in the oral cavity.

Finding dysplasia (precancer) while it’s still harmless is the key to preventing cancer.

In addition to WATS3D for screening and evaluation in the esophagus, CDx Diagnostics is partnering with healthcare professionals with an additional diagnostic test that help make oral cancer preventable.

OralCDx BrushTest®

A Painless Diagnostic Test to Assist Doctors in Preventing Oral Cancer

  • Almost all oral cancer starts as a small red or white precancerous spot, which can be seen during a careful oral examination.

  • These spots can contain unhealthy (dysplastic) cells that may still be harmless today, but can typically be removed before they progress into cancer.

  • The special brush has tiny bristles that collect cells as the tool rotates on the oral spot. It can be used anywhere in the mouth.

  • Once the cells have been collected, the sample is sent to CDx Diagnostics to help the doctors determine the cause of the common oral spot while making sure that the abnormality is not precancer or cancer. 




Oral Cancer Facts

  • Oral cancer kills about as many Americans as melanoma and twice as many as cervical cancer.

  • Oral Cancer is rising in women, young people and non-smokers.

  • Over 25% of oral cancer victims have no known risk factors.

Frequently Asked Questions about the OralCDx BrushTest

What is an oral spot?

Oral spots are tissue changes in the mouth, typically white or red areas.  They may be found on the tongue, inside of the cheek, or elsewhere in the mouth, and may occur in response to multiple factors such as long-term irritation. They are clinically referred to as “leukoplakia” (white) or “erythroplakia” (red) if their cause is not known.

How do I know if I have an oral spot?

Basically, you have to look and pay attention. If you notice a white or red “spot” or area while you are brushing and flossing it needs to be monitored. 

If it doesn’t go away within 10 to 14 days, it should be brought to the attention of your dentist or physician. They can test it to make sure it doesn’t contain abnormal cells, and if left alone, could progress to oral cancer. 

If they tell you that it’s “nothing” but it doesn’t go away, you need to bring it to their attention again and ask for a BrushTest or get a second opinion.



Test to Help Physicians Prevent Throat Cancer

Like oral cancer, throat cancer typically starts as a small white or red area. These can be seen in the office during an exam of your throat.

To help rule out the chance that an area in your throat contains pre-cancerous cells, your doctor can now take a sample right in the office with a specially designed brush. The sample is then sent for AI, computer-assisted laboratory analysis to CDx Diagnostics—the only lab in the world that can process this unique specimen.
