Abstract

Diseases of the gastrointestinal tract are often accompanied by changes in
the oral cavity. This is largely due to morphological and functional unity of the mucous
membrane of the mouth and entire digestive tract. According to numerous publications in
recent years, at the end of the XX-beginning of the XXI century, there is a significant
increase in the number of people suffering from cancer of the colon and rectum. This
localization accounts for 15% of all initially diagnosed tumors of all localizations (30% of
them are represented by rectal cancer).
