Vitamin D insufficiency common among breast cancer survivors
Vitamin D influences pathways related to cancer development, but little is currently known about vitamin D status in breast cancer survivors. Recent data taken from the Health, Eating, Activity and Lifestyle (HEAL) study showed a correlation between vitamin D status and breast cancer survivors. Vitamin D concentrations from 790 female breast cancer survivors were obtained and vitamin D insufficiency was found in 597 individuals - or 75% of participants. Average vitamin D concentrations were even lower among African American and Hispanic women.
Controlling for various factors such as body mass index (BMI), race/ethnicity, geography, season, physical activity, diet, and cancer treatments showed that stage of disease independently predicted vitamin D levels. In this group of breast cancer survivors the prevalence of vitamin D insufficiency was abnormally high. Based on these results, health professionals and clinicians should consider monitoring vitamin D status in breast cancer patients in addition to administering appropriate cancer treatments.

The Enemy - Free Radicals
In the process of creating energy within the furnace or fireplace of a cell, occasionally a charged oxygen molecule is created called a free radical.
A free radical is an oxygen molecule that has at least one unpaired electron in its outer orbit. This literally gives the molecule an electrical charge, which creates very rapid movement as it tries to find an electron from the tissue around it. If it is not readily neutralized by an antioxidant, it can go on to damage the cell wall, vessel wall, proteins, fats, and even the DNA nucleus of the cell.
The medical and scientific literature has shown us beyond a shadow of a doubt that the root cause of over 70 chronic degenerative diseases is the result of oxidative stress from excessive free radicals. These are diseases like heart disease, diabetes, strokes, cancer, arthritis, Alzheimer’s disease, macular degeneration, and the list goes on and on. These diseases concern us, and we would certainly like to avoid them. You will learn in this blog why taking nutritional supplements gives you the best opportunity to prevent or delay these diseases.

Lowering Homocysteine Levels / Ray D. Strand, M.D.
Most people seem to know their cholesterol level; however, they rarely know their homocysteine levels. Physicians just do not order this test routinely. The homocysteine level should be below 7, and higher levels cause greater risks of developing cardiovascular disease. Even though physicians may tell you that a homocysteine level of 12 or lower is fine, I would encourage you to try to get this level below 7. First, I would recommend taking 1,000 mcg of folic acid, 50 to 150 mg of vitamin B12, and 25 to 50 mg of vitamin B6. If you are one of those individuals who does not totally respond to B vitamins, you can consider adding Betaine (Trimethylglycine or TMG) to reduce your homocysteine levels. I recommend starting with 1 gram daily and building up to as much as 5 to 6 grams if necessary to get your homocysteine level down below 7, or at least below 8.There have now been over 50 clinical trials that have shown that those individuals who have elevated homocysteine levels are not only at higher risk of developing cardiovascular disease but also Alzheimer’s dementia and various cancers. Yet, there have not been any good studies showing that lowering your homocysteine levels actually decreases your risk of heart disease and stroke. My personal feeling is that they do not lower the homocysteine level enough and that there is very little difference between the control subjects and the treated group. Since we know that elevated homocysteine levels are definitely a risk factor for patients, wouldn’t it be best to lower their homocysteine levels to the safe range?
If you would like to know your homocysteine level and your doctor will not order it, members of my “Online Medical Practice” located at http://www.drraystrand.com/ can order this blood test in the US through my web site.
