Our second question is: What does the term precancerous mean? Essentially all breast tissue is precancerous or pre-neoplastic given the fact that there
11、 is a potential for the development of breast carcinoma in most post-pubertal breast tissuea potential that may never be realized and a risk that continuously increases with age. Are these lesions not proliferations that serve no physiologic purpose (i.e. not reversible), but display a risk (albeit
12、of variable magnitude) for subsequent development of carcinoma? If so, then why not use the term intraepithelial neoplasia of ductal, lobular or papillary types?,In all other body parts and organs, the term in situ carcinoma has been replaced by the term intraepithelial neoplasia.
