Vitamin D and breast cancer survival

Vitamin D could help women with breast cancer survival – this is very good news for women who are presently fighting breast cancer as well as for women who need badly breast cancer prevention tools.

Several scientific publications showed that low vitamin D levels were linked to a high risk of premenopausal breast cancer. Can the deficit of vitamin D trigger breast cancer? What are links between vitamin D and breast cancer? Can the vitamin D be the main key to breast cancer survival?

Many researchers are working on it in prestigious scientific institution in several countries but still today there are no 100% answers. But, at the same time, today doctors can provide many advices for breast cancer survival.

According to Carole Baggerly, founder of GrassrootsHealth, as much as 90 percent of ordinary breast cancer may in fact be related to vitamin D deficiency.

According to “Anticancer Research” women with breast cancer who have high levels of vitamin D in their blood are twice as likely to survive the disease as women with low levels of this nutrient (University of California, San Diego School of Medicine).

Vitamin D has several anticancer properties (effects), including the promotion of cancer cell death, known as apoptosis, and the inhibition of angiogenesis (the growth of blood vessels that feed a tumor).

According to Dr Cedric F. Garland and his co-authors “Vitamin D metabolites increase communication between cells by switching on a protein that blocks aggressive cell division – this prevents tumor growth and keeps the cancer from expanding in the blood supply. As long as vitamin D receptors are present, tumor growth is prevented and kept from expanding its blood supply. Vitamin D receptors are not lost until a tumor is very advanced. This is the reason for better survival in patients whose vitamin D blood levels are high.”

Based on scientific papers, some doctors suggest including vitamin D as an adjuvant to traditional breast cancer treatment modules. Actually there is no serious reason to wait for further detailed studies to incorporate vitamin D into well known breast cancer treatment schedules (regimens) since a safe dose of vitamin D needed to achieve high serum levels are already identified – above 30 ng/ml.

Vitamin D and breast cancer survival

A 2011 meta-analysis by Garland and colleagues estimated that a serum level of 50 ng/ml is associated with 50 percent lower risk of breast cancer.

According to the National Institutes of Health, the current recommended daily allowance for vitamin D is 600 IU for adults and 800 IU for people over 70 years old.

It is clear that different women can absorb vitamin D differently but according to scientists, women who consume 4,000 IUs of vitamins per day usually have the level of 50 ng/ml.

New scientific studies show optimizing vitamin D levels could double women chances of surviving breast cancer.

Breast cancer patients should restore their vitamin D levels to a normal range of 30-80 ng/ml.

Minimum protective level of vitamin D is 40 ng/ml.

You need at least 30 ng/ml of serum 25-hydroxyvitamin D to prevent cancer from spreading. More secure – better to achieve the levels as high as 80 ng/ml.

Human body produces vitamin D naturally from exposure to sunlight, but vitamin D is also identified in several food products such as fatty fish, fish liver oils, milks, cereals and other foods. For example, one tablespoon of cod liver oil has 1,360 IUs, a can of tuna contains 154 IUs per serving, and a cup of fortified milk and orange juice contains between 115 and 137 IUs of vitamin D, respectively.

Vitamin D can also be taken in supplement form.

To reach the minimum needed level of vitamin D (40 ng/ml) you should anywhere from 1,000 IUs to as much as 8,000 IUs of vitamin D3 per day. Some studies show that taking vitamin D supplements about 9,600 IU/day in 97.5% cases can insure the level of vitamin D in blood up to 40 ng/ml minimum.
