About 11 years ago a good friend of mine, who worked ICU, developed leukemia. While performing as a case manager about, six years ago, when getting reviews I talked to several case managers in the hospital who discussed some of the new admits (who happened to be licensed nurses in intensive care units) and were going to begin chemo and bmt treatments. Now I am teaching a class at a local college. One of the "new" instructors, who previously worked MICU and floated to other high acuity units, has now been diagnosed with ALL. Have heard some bioengineers remark in the past that some of the electronics associated with these units "may be altering our cellular code."
