Prevalence has previously been controversial, with contradictory reports from studies reporting either very low prevalence, or a high prevalence. [10] With the increasing availability of screening mammography, however, tubular carcinomas are being diagnosed earlier, and more recent studies suggest tubular carcinomas represent between 8% and 27% of all breast cancers.
DNA-based classification. Understanding the specific details of a particular breast cancer may include looking at the cancer cell DNA or RNA by several different laboratory approaches. When specific DNA mutations or gene expression profiles are identified in the cancer cells this may guide the selection of treatments, either by targeting these ...
Comedocarcinoma is a kind of breast cancer that demonstrates comedonecrosis, which is the central necrosis [1] of cancer cells within involved ducts. Comedocarcinomas are usually non-infiltrating and intraductal tumors, characterized as a comedo -type, high- grade ductal carcinoma in situ (DCIS).

The Breast Imaging-Reporting and Data System (BI-RADS) is a quality assurance tool originally designed for use with mammography.The system is a collaborative effort of many health groups but is published and trademarked by the American College of Radiology (ACR).
Atypical ductal hyperplasia (ADH) is the term used for a benign lesion of the breast that indicates an increased risk of breast cancer. [1]The name of the entity is descriptive of the lesion; ADH is characterized by cellular proliferation (hyperplasia) within one or two breast ducts and (histomorphologic) architectural abnormalities, i.e. the cells are arranged in an abnormal or atypical way ...
Breast diseases make up a number of conditions. The most common symptoms are a breast mass, breast pain, and nipple discharge. [1] A majority of breast diseases are noncancerous. [2] Although breast disease may be benign, or non-life threatening there remains an associated risk with potentially a higher risk of developing breast cancer later on ...
