Breast cancer screening is the medical screening of asymptomatic , apparently healthy women for breast cancer in an attempt to achieve an earlier diagnosis. The assumption is that early detection will improve outcomes. A number of screening tests have been employed, including clinical and self breast exams, mammography, genetic screening, ultrasound, and magnetic resonance imaging. A clinical or self breast exam involves feeling the breast for lumps or other abnormalities. Medical evidence, however, does not support its use in women with a typical risk for breast cancer. The use of mammography in universal screening for breast cancer is controversial as it may not reduce all-cause mortality and for causing harms through unnecessary treatments and medical procedures.
That is, do annual mammograms among women over 40 discover early-stage breast cancers that can be treated so that they never become deadlier late-stage tumors? Over the last three decades, diagnoses of early-stage breast cancers soared, largely due to routine mammogram screening. But the incidence of late-stage cancers declined only slightly.

Having a mother with breast cancer increases the chance that you could also develop the disease. Women who have a mother, sister, or daughter who developed breast cancer at a young age premenopausal have double the risk of the disease compared to those who don't have this family history. With new genetic testing techniques, breast cancer genes can be identified even before the disease develops. However, such testing is imperfect in terms of determining your risk.
Experts recommended discontinuing routine mammograms for breast cancer survivors with less than five years left to live as part of new imaging guidelines released Thursday. Radiologists should also consider stopping screening for those with a five- to year life expectancy, while continuing the practice for those beyond that range. The recommendations are part of new recommendations, compiled by dozens of experts in several fields and published in JAMA Oncology.
