precancer

Premalignant, preneoplasia Any of a broad group of conditions with a malignant predisposition; epithelial precancers may be
1. Glandular–eg, adenomatous hyperplasia–endometrium and adenomatous polyps–colon, stomach, which evolve towards adenocarcinoma of their respective organs or.
2. Squamous–eg, dysplasia of the uterine cervix or other urogenital mucosae; premalignant lesions of mesenchymal origin include prelymphoma and 'presarcoma'–an ad hoc coinage, the latter of which may be due to predisposing factors–eg, osteosarcoma may arise in Paget's disease of bone, radiation, hereditary multiple exostoses, polyostotic fibrous dysplasia, enchondroma, Maffucci's enchondromatosis; osteosarcomas may be induced experimentally by various trauma–chemical–eg, turpentine, mechanical– eg, local pressure, indwelling foreign bodies, ischemia–eg, vessel clamping. Cf Preneoplastic state. See Fragile X syndrome, Hereditary neoplasms, Premalignancy.
