A new study of women with early stage, localized breast cancer identifies new patterns and risk factors for invasive disease that may influence how patients are treated. Published in the May 15, 2006 issue of CANCER (http://www.interscience.wiley.com/cancer-newsroom), a peer-reviewed journal of the American Cancer Society, the study reveals that patients with lobular carcinoma in situ (LCIS) are actually at higher risk of developing advanced stage tumors than previously thought. In addition, women with ductal carcinoma in situ (DCIS) who are under 50 years old, African-American or Hispanic are at increased risk of developing advanced stage invasive tumors.
