Update on Breast Cancer Screening

摘要

Breast cancer is the most frequently diagnosed non-cutaneous cancer in US women, with more than 190,000 women suffering invasive disease yearly. Screening mammography has been the cornerstone of assessment for breast cancer for over 2 decades, leading to earlier diagnosis and treatment and, as a result, reduction in breast cancer mortality.1 An estimated 1 of 8 women is at risk for developing breast cancer in her lifetime, and the incidence increases with age. Other factors, such as lifestyle and family history, may increase breast cancer risk. Nurse practitioners (NPs) who provide primary care to women must use current guidelines for breast cancer screening and be able to assess for personal risk factors.
