I am very concerned about a problem in a NICU in my area. Some of the nurses (12) have developed thyroid problems. One has cancer, one had to have a partial thyroid removal and the others are on thyroid medication. The hospital is investigating if something they are being exposed to is causing this, which to me is obvious. I was wondering if this is just an isolated incidence or is this common in other NICU's as well. Thanks in advance.
