Diagnosis of mouth cancer

In an endoscopy, a flexible tube (endoscope) is used to examine the nose, sinuses, larynx (voice box) and pharynx (throat). 


Tests such as CT and MRI scans help to determine how far the cancer has spread. Staging helps your doctor decide on the best treatment options for you.

Screening for mouth cancer

Australia has no national mouth cancer screening program. Talk to your doctor about symptoms. Visual inspection and fluorescence are also used by dentists to detect oral cancer.

Preventing mouth cancer

Around 59% of Australian oral cancers are smoking-related. Drinking too much causes 31%. Quitting smoking and drinking moderately will greatly lower your chance of mouth cancer.
