Breast Cancer T2 McGraw-Hill's NAPLEX® Review Guide YR 2011 FD 2011 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-175562-7 LK accesspharmacy.mhmedical.com/content.aspx?aid=7251045 RD 2024/04/16 AB Breast cancer is the most prevalent malignancy in US women. It was estimated that approximately 192,000 US women were diagnosed with breast cancer in 2009. This number represents approximately 27% of all new cancer cases diagnosed in US women annually. Moreover, in 2009 an estimated 40,000 US women died of breast cancer making it the second leading cause of death from cancer after lung cancer. Breast cancer rarely affects men (2009 US estimates: 1910 new cases, 440 deaths). While breast cancer causes significant morbidity and mortality, death from breast cancer in the United States has been gradually declining since the early 1990s. The implementation of early detection guidelines and effective adjuvant therapy have been identified as approaches resulting in this positive trend.1,2
