The chronic myeloproliferative disorders consist of chronic myelogenous leukemia, polycythemia vera (p. vera), primary myelofibrosis, essential thrombocythemia, chronic neutrophilic leukemia, and chronic eosinophilic leukemia. All of these disorders involve dysregulation at the multipotent hematopoietic stem cell (CD34), with one or more of the following shared features:
Overproduction of one or several blood elements with dominance of a transformed clone.
Hypercellular marrow/marrow fibrosis...
According to the findings of a 2006 Environmental Protection Agency
scientific advisory panel, the primary chemical used to make Teflon --
perfluorooctanoic acid or PFOA -- is a "likely human carcinogen." But that
applies only to PFOA that has been emitted into the environment.
"The link between Teflon cookware and cancer is an entirely different
subject," says Robert Wolke, professor emeritus of chemistry at the University
of Pittsburgh and author of the two-part book series What Einstein Told His
Cook. "There is no PFOA in the final Teflon product, so there is no risk
that it will cause cancer in those who use Teflon cookware."
That said, Wolke warns, "heating a Teflon pan to 500 degrees or more" (as
happens when we leave empty pans on high heat by mistake) can result in smoke
and gases that can cause flu-like symptoms in humans and kill pet birds.
So keep an eye on your stovetop and keep your smoke alarms in good working
