Is every red patch cancer?
No; the cause needs assessment.

What can a persistent red patch in the mouth mean?
Erythroplakia describes a red mucosal patch that cannot be attributed to another cause after assessment. It carries an increased risk of abnormal cells and needs prompt professional investigation. A red patch alone does not prove either erythroplakia or cancer.

Red is not a diagnosis
Irritation, inflammation and other causes can also produce red areas. Colour alone cannot distinguish them.
Have it assessed
An unexplained red or red-and-white area needs prompt examination, even without pain. There is no need to wait for a time threshold.
Clarify the tissue
A tissue sample may be necessary when findings are suspicious. Tissue examination establishes what cellular changes are present.

Often confused
Red patch and erythroplakia
The term follows assessment of other causes. It is not the result of a colour test.
Quick answers
Can I identify it from a photograph?
No. Online images cannot replace examination and, where needed, biopsy.
Is a painless patch harmless?
Not automatically. Significant mucosal changes may cause few symptoms.
Should I try a mouthwash first?
Do not delay assessment of an unexplained persistent patch while trying rinses. Do not use caustic products or remove it yourself.

Editorially suggested question to discuss with Dr Niusha Barahmand Pour:
Which causes need to be excluded, and is a biopsy necessary?
Arrange prompt dental or medical assessment of an unexplained red or red-and-white patch; contact another suitable practice if your usual one is unavailable.
