In all soft tissues of the mouth, tumors may develop, mostly after injury or as a result of benign lesion. These can be removed under local anesthesia with minor surgery and sent for histological examination, since rarely, clinical evaluation may be false. Moreover, it should be noted that the oral cavity is a frequent area where diseases occur, such as lichen planus, manifested in the form of white plaque (leukoplakia) or ulcers (wound). Their confirmation is possible by a biopsy carried out by a qualified surgeon with appropriate knowledge of oral pathology. Finally, it must be noted that rare cases of malignancy appear in the mouth, and in any case, anything that raises a concern, such as wounds that do not heal in a reasonable amount of time, should be investigated with the help of specialists.
