People mostly recognize vitamin D as essential element to obtain strong bones. Indeed, vitamin D is mostly used in the prevention and treatment efforts for rickets. Patients diagnosed with osteoporosis, bone pain, inherited disease of brittle and easily broken bone, and also bone loss condition called hyperparathyroidism will be given vitamin D on the treatments. Human body needs vitamin D to use calcium intake from daily meals. Several foods also contain vitamin D, but only in small amounts. Fatty fish like tuna, salmon, sardine, mackerel, and herring are few of those foods. Dairy products such as fortified milk and cheese also contain vitamin D. Adding whole egg, liver and fortified margarine into your diet can give more supplies of vitamin D. It requires sunlight exposure for the skin to be able to synthesize vitamin D.
The latest research indicates vitamin D also has part in preventing and treating several diseases, including high blood pressure, glucose intolerance, type 1 and type 2 diabetes, and also multiple sclerosis. Further studies proofs that low level vitamin D is slightly responsible to increasing risk of breast cancer. Previously, a number of studies have associated low level vitamin D to higher risk of breast cancer. However, those studies was failed to explain the mechanism of how vitamin D can lower the risk of breast cancer. Later, it was summarized in a paper the mechanism of how vitamin D can lower the risk of getting breast cancer, as well as vitamin D’s important roles in inhibiting of invasion, suppressing COX-2 expression, also its role in metastasis and tumor angiogenesis which automatically lower down levels and biological activities of proinflammatory prostaglandins. The fact is that vitamin D has important role in endocrine system which works to control cells growths and differentiation. Endocrine system also has parts in the synthesis process of important enzymes, some adrenal hormones and even has part in DNA repair process and other DNA functions. New research reported new and important function as vitamin D can significantly affect nuclear receptor sites on cell membranes, as well as on the increasing amount of cancer cell membranes.
Through a series of tests in the laboratory, vitamin D is able to slow down the growth of new blood vessels in tumor required for its metabolism. As we all know, cancer cells grow actively and rapidly without being able to get classified into lung, or breast, or liver cells. Vitamin D can makes these overly unclassified cells back to normal cells. Bottom line is that vitamin D can set everything in cancer cell back to its former function, taking back cancer cells’ genetic messaging back to cytoskeleton. It can even minimize cell division. It works on genes and switches it on and off. Vitamin D works a miraculous work of calming down cancer cells which prevents cancer from spreading. Hopefully, in the future vitamin D can be used to bring cancer cell to normal healthy cell. Adequate dosage of vitamin D oral intake is safe. Reported side effects from vitamin D overdose are drowsiness, headache, weakness, tiredness, nausea, vomiting, etc. By incorporating healthy lifestyle of healthy diet, routine exercise, avoiding stress, regular health screening, to regular checking on vitamin D level, a person can prevent the re-occurence of breast cancer and side effects.
