How useful is vitamin D

Women with an identified breast cancer have a 2-fold chance of surviving with a high level of 25-hydroxyvitamin D in the blood serum than with its deficiency. This is the conclusion of a meta-analysis of five independent studies of the control problem over this oncopathology.

Vitamin Rescuer

Within the scope of all scientific works, observation was conducted in general for 4443 patients with a malignant breast tumor. It has been established that for 10 years the mortality from neoplasm was 44% less in those women in whom the level of vitamin D was the highest. The highest mortality was recorded among those who had the lowest values ​​in the blood of the active form of the vitamin.

A similar pattern is found not only in breast cancer, but also in malignant tumors of the large intestine and prostate.

Statistical analysis has found another encouraging fact: with a sufficient level of vitamin D in the body, the risk of developing metastases is reduced by 94% compared with those patients who are diagnosed with a deficiency of this substance.

What is the essence of the antitumor effect of vitamin D

Scientists have presented a logical chain:

• Strengthening the synthesis of epithelial cadherin. This substance causes gluing of epithelial cells and adherence to them tightly to each other.
• In a tight conglomerate cells divide much more slowly and reach the final stage of differentiation, without the chance to malign. Thus, the leading factors of malignancy are excluded: unlimited fission rate and insufficient differentiation of cells forming a cancer clone. Even if the cancer is formed, it will be the least "evil".
• The denser the epithelial layer, the less likely the tumor to break through into the lymphatic channel with the formation of metastases in various organs.

The favorable regularity is established: the closer to the norm the vitamin D content in the body, the slower the growth of cancerous growth.

How to protect yourself from a tumor

Study leaders emphasize the great importance of maintaining a certain concentration of vitamin D in the serum:

• for the prevention of breast cancer - 40-60 ng / ml;
• to reduce the aggressiveness of an already existing tumor - 80 ng / ml.

Dr. Cedric Garland of the University of Feinberg insists that the diseased need to immediately increase the content of this salvage in the blood, giving up to 40,000 units per day of its synthetic analogue. In addition, Dr. Adam Murphy of the School of Medicine in Chicago emphasizes the importance of simultaneously maintaining sufficient serum calcium( 8.5-10.2 mg / dL).This corresponds to his daily intake of 1500 mg. To maintain reserves, it is best to organize special meals, and to replenish the missing amount by taking calcium-containing medications.
