Cancer
of the cheek is usually
called leukoplakia or white plate.
Doctors call this smoker's patches.
Poisons from burning tobacco
enter directly into the cells
of the lining of the mouth.
A look inside a
smoker's mouth will show a yellowish-white
leathery looking area in the cheek.
These changes, called leukoplakia,
are early abnormalities which can
lead to cancer.
