Vitamin D3 Benefits Breast Cancer Big Time!

“The preponderance of epidemiologic data indicates vitamin D3 deficiency is associated with an increased incidence of breast cancer. Furthermore, recent studies show that low vitamin D levels are associated with increased breast cancer recurrence and mortality rates”

I’ve never understood why conventional oncology doesn’t prescribe evidence-based, non-conventional therapies such as vitamin D3. When you want to reduce the risk of a breast cancer diagnosis, the risk of a breast cancer relapse, reduce the risk of breast cancer metastasis, reduce bone pain caused by aromatase inhibitors or enhance your bone health, the studies linked and excerpted below cite the benefits of vitamin D3 as an inexpensive, non-toxic therapy.

Full disclosure. I am a cancer survivor and cancer coach. I have taken many different types of supplements (vitamins, minerals, antioxidants, etc.) for years and continue to do so. I achieved cancer-free status from my incurable blood cancer called multiple myeloma in early ’99 where I remain today. Yes, I believe in the importance of nutrition/diet, exercise, detoxification and other evidence-based therapies as well. But taking certain supplements daily such as vitamin D3, omega 3 fatty acids, vitamin C and others, I believe are central to cancer patients and survivors- all cancer patients and survivors.

I am not being critical of conventional/traditional oncology when I say that they are limited in their support of cancer patient and survivors. I understand the importance of the FDA and their tight control of medicine in the United States. But as a long-term cancer survivor I see living with cancer as requireing much more than what conventional oncology offers a cancer patient.

I take Life Extension Vitamin D3, 1000 mg. pearls. Convenient, inexpensive. Tested and approved by ConsumerLab.com.

Have you been diagnosed with breast cancer? Are you considering undergoing an aromatase inhibitor? Are you worried about osteoporosis? Please scroll down the page, post a question or commet and I will reply to you ASAP.

Thank you,

25-OH vitamin D is the accepted assessment of vitamin D status and provides a comprehensive measure of vitamin D from all sources (diet, sunlight, and supplementation). Although there is not a “standard” definition of vitamin D status, a widely accepted classification is deficiency at <20 ng/ml, insufficiency at 20–31 ng/ml, and an optimal range of ≥32 ng/ml []. Despite a number of clinical trials, researchers and clinicians remain divided on the proper supplementation amount to achieve a normal 25-OH vitamin D level…

It is imperative that breast cancer patients maintain optimal vitamin D levels to minimize the risk of treatment-related problems such as bone loss, arthralgias, and falls. Clinicians need to carefully consider the vitamin D regimen (amount and type) when treating vitamin D deficiency in breast cancer patients due to the limited efficacy of daily low-dose supplementation…”
