Sept. 10 (Bloomberg) -- Debbie McCarron, who has had breast cancer twice, talks about her advocacy of genetic testing and the proper screening of results. McCarron learned she had a gene linked to breast cancer in July 2009 when her genetic counselor reviewed a DNA test from December 2006. McCarron had been under the assumption the results from the 2006 test were negative for the gene. (Source: Bloomberg)
