Cancer of the mouth has to be diagnosed by a qualified dental surgeon who has the knowledge on the oral structures.The incidence of Oral cancer
in Asia and India are on the rise due to improper oral hygiene
& neglect.One can easily identify for the warning signs such as a long standing sore,ulcer or a lump.Basically most of the cancers are not revealed until it reaches a stage when it becomes difficult for the clinician to treat it.Therefore,I would ADVICE to all to have a regular routine screening of one's mouth every 6 months atleast.
Coming to the gutkha chewing it is a form of tobacco and mixture of some obnoxious agents. They are cancer producing agents.They cause heat and chemical reactions in the mouth which eventually breaks the soft tissues to cause sorenes,ulcer leading to cancer.The Gutkah chewers experience a condition called as Oral Submucous fibrosis
.Which,is a slow ,progressive fibrotic stiffening of the oral mucosa
particularly the inner cheek,floor of the mouth or any area resulting in burning,ulcer.and slowly closing the mouth producing inability to open the mouth. Therefore abstinence from the chewing gutkha and seeing a good dentist
at the earlist is most important.
