It has been known for many years that vitamin D prevents hyper-proliferation of cells in the human body. Research has shown that actual breast cancer responds in a test tube to activated vitamin D. But can vitamin D PREVENT breast cancer? A study just published in the September 2011 issue of Anticancer Research answers that question clearly.
There are 11 case-control studies on the risk of breast cancer by 25-hydroxyvitamin D levels that have been published. The authors of this meta-analysis combined the data to relate the risk of breast cancer to 25-hydroxyvitamin D levels.
The study confirmed the connection. This meta-analysis provides proof. A serum level of 47 ng. resulted in a 50% lower risk of breast cancer.
The studies did not determine the maximal beneficial effort of vitamin D on preventing breast cancer. It would be expected that the prevention of breast cancer would keep increasing with a higher level of vitamin D above 47 ng. Vitamin D levels in nature are higher than 47.
The study also did not look at the treatment of established breast cancer with vitamin D.
Do many women have a blood level of 47 ng of vitamin D? I have obtained about 4000 blood levels of 25-hydroxyvitamin D in men and women over the past 7 years, mostly people from Southern New Jersey but also some from California, Florida, Massachusetts, Rhode Island, and Texas were included. Only a very occasional person has that high a level. One woman who gardened all summer had a level of 70 ng. One woman who walked 6 miles a day all year round was quite memorable; she had a level of 110 ng. A fisherman had a level of 60 ng. I’ve seen less than 20 people who had a level of 47 ng or higher without taking a major dose of vitamin D. About 2/3rds of men and women have very low vitamin D levels below 32 ng.
In order to obtain a level of 47 ng, most people need to take at least 5000 units of vitamin D daily. Only occasionally do some people require less. The well publicized dose of 2000 units a day is intended for people who are healthy, and who have never obtained a blood level. In most cases, it will not raise a level below 32 ng to 47 ng. I’ve seen many people who already take 2000 units a day who have levels below 32 ng.
There are several breast cancer fund raising organizations that raise many millions of dollars to cure breast cancer. Much of the money is used for research grants to cancer researchers. I have seen their spokespeople on television, and they have made it clear they are not interesting in devoting their efforts to PREVENTION. They have no plans to publicize studies such as these.
If there was one well publicized “RACE FOR PREVENTION” publicizing the facts in this study, instead of the usual “RACE FOR THE CURE”, more women would be saved from breast cancer over 5 years than have been helped by chemotherapy since 1974, the year that the “War on Cancer” started.
Although this particular study was done on breast cancer, there are extensive somewhat similar studies done on men with prostate cancer. There are also many studies done with various type of cancers including cancer of the uterus and pancreas.
In a perfect world, this medical study should be publicized in newspapers and television news. As so often happens, unfortunately it will most like not be publicized.
