Atypical hyperplasia is a high-risk premalignant lesion of the breast. It is believed that atypical ductal hyperplasia (ADH) is a direct precursor for low-grade mammary ductal carcinoma , whereas atypical lobular hyperplasia (ALH) serves as a risk indicator.
There are two types of atypical hyperplasia: lobular and ductal; the lobular type is associated a greater cancer risk of approximately five-fold and especially high relative risk in premenopausal women. Atypical ductal hyperplasia is associated with a 2.4-fold risk. [20] In contrast, a New England Journal of Medicine article [21] states that ...
Presence of high-risk breast lesions like lobular carcinoma in situ (LCIS), atypical ductal hyperplasia (ADH) and atypical lobular hyperplasia (ALH). [7] Having dense breasts or breasts with diffuse microcalcification, as the screening for breast cancer is made difficult.
Premalignant lesions are morphologically atypical tissue which appear abnormal when viewed under the microscope, and which are more likely to progress to cancer than normal tissue. [7] Precancerous conditions and lesions affect a variety of organ systems, including the skin, oral cavity, stomach, colon, lung, and hematological system.
