Precancerous

A term applied to any condition in which there is a tendency for cancer to develop. There are 3 types of such conditions. In the 1st, there are no tumours present but the condition carries an increased risk of cancer. In the 2nd, there are noncancerous tumours that tend to become cancerous or are associated with the development of cancerous tumours elsewhere. The 3rd type comprises disorders which have irregular features from the beginning but do not always become fully cancerous.
