Please Read! Check Vit. D, 25-Hydroxy Levels
New research suggests that breast cancer patients with high levels of the vitamin in their blood are twice as likely to survive the disease than patients with low levels...
The studies included a total of 4,443 patients with breast cancer and were performed between 1966 and 2010. All patients were followed for an average of 9 years. Patients were divided into groups dependent on the levels of 25-hydroxyvitamin D in their blood. Women in the "high" group had an average of 30 nanograms per milliliter (ng/ml) of 25-hydroxyvitamin D in their blood, while women in the "low" group had an average of 17 ng/ml in their blood.
The investigators note that the average blood level of 25-hydroxyvitamin D for breast cancer patients in the US is 17 ng/ml.
The team found that women who had high levels of 25-hydroxyvitamin D in their blood had around a 50% lower fatality rate, compared with women who had low levels of 25-hydroxyvitamin D in their blood.
Explaining why he believes vitamin D decreases fatality rates for breast cancer patients, Prof. Garland says that vitamin D metabolites increase communication between cells by activating a protein that halts aggressive cell division. "As long as vitamin D receptors are present, tumor growth is prevented and kept from expanding its blood supply," he adds...
Prof. Garland says further research is needed to confirms the team's findings, he believes there is no reason why people should not increase their vitamin D intake now, after confirming with their health care provider that it is safe to do so. He refers to a study he conducted in 2011, which found that a 50 ng/ml level of 25-hydroxyvitamin D in the blood - a level that can be reached with an intake of 4,000 international units (IU) of vitamin D a day - reduces breast cancer risk by 50%.
