A precancerous condition (or premalignant condition) is a generalized state associated with a significantly increased risk of cancer. If left untreated, these conditions may lead to cancer.
Premalignant lesion is a morphologically altered tissue in which cancer is more likely to occur than its apparently normal counterpart.
Examples of pre-malignant conditions include actinic keratosis, Barrett's esophagus, atrophic gastritis, and cervical dysplasia.
The term was coined in 1875 by Romanian physician Victor Babeş.
