Abstract
In 1967, the World Health Organization (WHO) established a WHO Collaborating Centre for Oral Precancerous Lesions in Copenhagen. In 1972, while work was being carried out at this center, a meeting arranged by WHO was held in Geneva with the aim of defining precancerous lesions in different organs of the body. As result of this meeting, the suggestion of distinguishing between precancerous lesions and precancerous conditions was made. A precancerous lesion is a morphologically altered tissue in which cancer is more likely to occur than in its apparently normal counterpart. A precancerous condition, on the other hand, is a generalized state associated with a significantly increased risk of cancer. Examples of precancerous conditions are syphilis, submucous fibrosis, and lichen planus.
