Advances in diagnosis and management of breast premlignant disease

Breast precancerous disease is a group of benign proliferative disorders which is correlated to breast cancer, the latter being the most common female cancer. The relative risk of developing breast cancer within 10-20 years after diagnosis is quite different among histological types of premalignant disease, varying from 1.5 to 10. Most of these diseases increase the rate of cancer in both breasts. While further researches on the relationship between breast premalignant disorders and breast cancer are going on, the diagnosis and management of these precancerous conditions seem to be more and more important for the prevention of breast cancer.
