I haven't been here in a while and I know this thread is a little old.
Could anyone comment on the reported increase risk of pancreatic and esophageal cancer in patients with high(> 40ng/ml) levels of 25-hydroxyvitamin D?
This was mentioned in a "Perspective" piece in the New England Journal of Medicine(April 14, 2011, pg. 1387) and referenced a study by Helzlsouer entitled, " Overview of the Cohort Consortium Vitamin D Pooling Project of Rarer Cancers" , Am J of Epidemiology 2010; 172:4-9.
I haven't tracked the paper down yet. Just wondering if anyone was familiar with it.
