Overview
Historical Perspective
Breast cancer was first described in the Egyptian literature. In 1976, mammography became officially recommended by the American cancer society for screening the breast cancer.
Classification
Breast cancer may be classified according to anatomy into 4 subtypes: ductal, lobular, sarcoma, and lymphoma.
Pathophysiology
Genes involved in the pathogenesis of breast cancer include BRCA1, BRCA2 and p53. On microscopic histopathological analysis, minimal tubule formation,marked pleomorphism, and numerous mitotic figures are characteristic findings of breast cancer.
Causes
The cause of breast cancer is not yet known exactly, though many risk factors can increase the chance of developing breast cancer.[1]
Differentiating Epithelioid sarcoma from other Diseases
Breast cancer must be differentiated from other diseases that cause mass in the breast such as fibroadenoma, fibrocystic disease of the breast, mastitis, galactocele, traumatic fat necrosis, intraductal papilloma, and lipoma.
Epidemiology and Demographics
The prevalence of breast cancer is approximately 124.8 per 100,000 women per year. The number of deaths was 21.9 per 100,000 women per year, based on 2010-2012 data.
