Vitamin D and Breast Cancer The results of several studies linking Vitamin D levels and breast cancer have recently made the news. One of the findings indicated that women with inadequate levels of Vitamin D when they were diagnosed with breast cancer were more likely to have their cancer spread and more likely to die. Sadly, in one study, only 24 percent of the women had adequate levels of Vitamin D. However, in a Canadian study, teens with high levels of Vitamin D were especially fortunate – up to 45 percent less likely to develop breast cancer. Lead researcher of this study, Julia Knight of Mt. Sinai Hospital in Toronto, speculated that exposure to Vitamin D as breasts are developing may play a key role in the reduction of risk of developing breast cancer later in life. Researchers stressed that their findings only show an association, and that further study is needed. Although the research is promising, there is a possibility that high levels of Vitamin D are simply the result of a healthy lifestyle. If you have been diagnosed with breast cancer, it’s certainly worth talking with your doctor about testing to determine your Vitamin D level. If you have not been diagnosed with breast cancer, but are anxious to make sure your Vitamin D level is adequate, diet and daily sunshine are your best tools. Food sources of Vitamin D include dairy products, salmon and tuna, but it can be difficult to get sufficient amounts through diet alone. There is no RDA (Recommended Daily Allowance) established for Vitamin D, but the generally accepted recommendation is 200 IU (up to age 50), 400 IU (ages 51-70) and 600 IU (ages 70+). Some experts think these levels are too low. However, Vitamin D can be toxic in high doses, and it is important to discuss supplements with your health care provider. Sun exposure is the easiest way for the body to get Vitamin D. The ultraviolet rays from the sun trigger the natural synthesis of Vitamin D in our bodies. Only ten minutes of exposure can supply anywhere between 2000 and 5000 IU of Vitamin D. Researchers have not been able to determine why low Vitamin D levels are linked to breast cancer. One theory is that breast cancer may be more aggressive when Vitamin D levels are low. On the other hand, a high Vitamin D level may be the result of other healthy lifestyle choices that reduce the risk of developing breast cancer or having it spread. Diet and lifestyle are two things we have control over in our fight against breast cancer. It makes sense to take simple steps to make sure our diets contain foods rich in Vitamin D and that we get a few minutes in the sun whenever possible. | Related Articles | Previous Features | Site MapContent copyright © 2008 by Gail Armanini.
