Breast cancer is the second most common malignancy in the world and is the fifth leading cause of cancer death in women. There is no method to determine who will develop breast cancer at some time in their life. Some methods are available to detect the tumor early. One of those methods is mammography screening. The idea of this test is to find a lesion(s) in the breast that may correspond to a stage cancer as early as possible.
Explanation:
It is defined as screening in examining a group of people in order to detect a disease or people with a high risk of developing the disease. For a screening test to be effective and efficient, several requirements have to be met, for example, that the disease to be screened must have a significant incidence, the test must have a high sensitivity and specificity, the cost must be relatively low or affordable, The test should be easy to perform and with limited side effects and/or complications. In some countries, guidelines for screening breast cancer with mammography have been established, there is controversy over when to start screening, the recommended interval and to what age the screening was performed. Mammographic screening for women between 50 and 69 years of age is recommended globally.
