Abstract	TO THE EDITOR: Weinberg and colleagues ' article (1) high-lights the complexities of using genetic polymorphisms and their associated cancer risk to encourage lifestyle modifica-tions. The study attempts to consider risks, benefits, and potential barriers to personalized medicine and associated patient and provider uptake. The authors discuss their ratio-nale for using trained nurses in lieu of genetic counselors, stating that the number of genetic counselors seems inade-quate to meet health service needs even in high-risk settings, citing a reference from 1990 (2) that does not reflect current data. Currently, there are more than 4000 certified genetic counselors in the United States, all of whom are trained to provide a cancer genetics consult and approximately 30 % of whom report cancer genetics as their primary specialty (3).
