Background: The amount of doses received in mammography is one of the biggest concerns in the world. According to some statistics, every 12 minutes a woman dies due to breast cancer. Mammography concerned to detect breast cancer at an early stage of the disease as well as for screening, however due to the risk of exposure, the increasingly and widespread use of mammography for breast cancer scr...
Breast carcinoma is the most common malignancy among women in developed countries, and its incidence is on the rise in developing countries. In Malaysia, it accounts for about 30% of newly-diagnosed female cancers [1]. Imaging of the breast can be traced to its earliest origins in 1913 when a surgeon, Albert Salomon, used radiography images of mastectomy specimens to demonstrate the spread of b...
Background & Objectives: Breast cancer is the most common cancer among women and one of the leading causes of death in the productivity ages. Mammography screening is the main method for the diagnosis of breast cancer. While analog mammography counts as the standard method of screening, the digital one can be an alternative. This review compared the effectiveness and safety of these technologie...
