D3 and breast cancer and how it relates. I am always on the lookout for more information and studies that support natural alternatives to assist with hormone health challenges. October is Breast Cancer Awareness month and this should remind us of the need for natural plan of attack for breast cancer.
Reduced risk of Breast Cancer: Yet another benefit of sunshine-induced vitamin D!
We may not have found a cure but we do know that Breast cancer was one of the first cancers identified as having protection from vitamin D. Now there is ample evidence that vitamin D lowers breast cancer risk.
Two reports presented by The American Association for Cancer Research documented this risk reduction in breast cancer….. A research group from the University of California at San Diego found that the higher the blood level of 25-hydroxyvitamin D, the lower the risk of breast cancer. Women with a blood level of 52 ng/ml had 50 percent less breast cancer risk than women with a serum level of 12 ng/ml or less. To achieve this blood level, intake of about 3,000 IU of vitamin D daily or a daily sunlight exposure equivalent to women who live in Southern California and spend considerable time outdoors is required.
In another study, Toronto researchers interviewed 576 patients who had been diagnosed with breast cancer and 1,135 women who had no breast cancer. They found a direct correlation between reduced breast cancer risk and exposure to sun as an adolescent. Women who worked an outdoor job between the ages of 10 and 19 had an estimated 40 percent reduced risk of breast cancer, and women who participated in frequent outdoor activities between the ages of 10 and 29 lowered their breast cancer risk by an estimated 35 percent.
A study in Norway found that women diagnosed in summer had a better two-year survival rate than those diagnosed in winter. Vitamin D levels are higher in summer than winter, which may explain the findings.
Children should be exposed to the sun!!
One of the researchers said: “What you are exposed to during breast development may be particularly important in determining future breast cancer risk. Current thinking is that exposures during adolescence or before a full-term pregnancy may have a greater effect, as that is when breast tissue is going through the most rapid development.”
The thinking now is don’t waste your money on sunscreen and get as much sunshine as possible!
If you can’t get out in the sun, take 3,000 to 4,000 IU of vitamin D from cod liver oil and other supplement sources daily. (http://MaxxAlive.com/D3 spray). Keep in mind that researchers have found that the upper limit for safe vitamin D intake is 10,000 IU daily.
How do you know if you have enough D3?
Test your D3 levels with a test that you can do at home and send to the lab. Testing is appropriate both spring and fall. Testing will help you to determine your supplementation program.
