Definitions for "Precancerous"
Abnormal cellular changes that are potentially capable of becoming cancer. These early lesions are very amenable to treatment and cure. Also called pre-malignant.
Abnormal cellular changes that have the potential to become malignant (cancerous).
Condition of tissue that is defined as the potential preliminary phase of a carcinoma. Depending on the statistical probability of a lesion to change into a malignant stage precancerous lesions are divided in facultative, which means they carry a low degenerating potential or obligate which means they carry a high degenerating potential.
