NOV. 11, 2009 — Just one week after a leading vitamin D researcher declared that breast cancer incidence could be “virtually eradicated” by raising vitamin D levels back to natural status of those who live and work outdoors in sunny climates, another study has shown that most women with breast cancer are vitamin D deficient.

A study published in the Journal of Clinical Oncology this month showed that only 6 percent of early-stage breast cancer patients had sufficient vitamin D levels. Further, after a year of vitamin D supplementation at a dosage twice as high as is currently recommended, only 11 percent in the study got their vitamin D levels up to sufficient status.

This is not surprising since vitamin D scientists are now talking about dosages of vitamin D 10-20 times higher than the current recommendations to get women up to natural vitamin D levels. Getting a full-body suntan has as much vitamin D as 100 glasses of milk.

Columbia University oncologists Dr. Katherine D. Crew and Dr. Dawn Hershman wrote a review of the new study in the online American Journal of Hematology and Oncology. Click here to read the review.
