Sunshine makes us feel good and makes us healthier and protected from cancer.
Actually, a late research has proved that vitamin D, which is created in our organism due to sun exposure keeps us safe from breast, prostate and colorectal cancer.
This is very important since the cancers are one of the leading health conditions that cause death in the United States.
Dr. Cedric F. Garland of the University of California’s San Diego Moores Cancer Center is the epidemiologist who linked the lack of vitamin D and cancer.
Numerous studies prove that vitamin D suppresses cancer, by stimulating cellular differentiation, disabling cancer cell growth, inducing apoptosis and disabling blood vessel production into the tumors.
The conclusion released in the Journal of Cancer, indicated that 4000 IU/d of vitamin D3 could disable cancer development, as measured by the main biomarker 25-hydroxycholecalciferol [(OH)D].
Studies conducted on breast cancer patients discovered that proper to high vitamin D amounts may reduce the cancer fatality by 44%.
Actually, women with too low vitamin D levels had 94% increased risk of developing metastases than patients with proper levels. Women with low vitamin D levels had 73% increased risk of death.
“Doctors need to understand how important proper serum vitamin D levels (40-60 ng/mL) are for cancer prevention. They should encourage their patients to control their vitamin D levels regularly, particularly in winter, which will allow them to keep their vitamin D levels in normal,” says first author Sharif B, Mohr, MD, from the Naval Health Research Center in San Diego.
Patients who are already diagnosed with breast cancer, vitamin D levels may increase up to 80 ng/mL, he stated for Medscape Medical News.
Reduced levels of vitamin D raise the possibility of developing breast cancer and are related with aggressive tumors and fatal consequences.
“Although further research must be done, our research indicates that women at risk of breast cancer should check their vitamin D levels and try to normalize them,” says Brian Feldman, MD, PhD, assistant professor of pediatrics.
A recent research from the Northwestern University Feinberg School of Medicine indicates that there is a relation between reduced vitamin D levels and aggressive prostate cancer. Actually, it has been proven that reduced serum vitamin D increase the possibility of prostate cancer development.
Vitamin D prevents proliferation and differentiation of cancer cells.
The study conducted in the period from 2009 to 2014 was included in a large epidemiologic research of 1760 cancer screenings compared to healthy controls.
“If you add prostate cancer cells into a dish with vitamin D, their development decelerates and they become less invasive, which greatly lowers the possibility of their apoptosis,” states Adam Murphy, lead author and assistant professor of Urology, Northwestern University.
“Our late research has proven that people who aren’t impacted by prostate cancer have higher vitamin D levels than prostate cancer patients.”
Vitamin D strengthens the bones, fights against rheumatoid arthritis and other kinds of cancer.
It has been proven that supplementation with vitamin D3 is able to disable the cancer from expanding.
The combination of calcium and vitamin D decreases the possibility of developing any type of cancer in postmenopausal women by incredible 77%.
These vitamins produce E-cadherin, a substance that structures cells and holds them together. This disables the penetration of cancer cells into organs and tissues in the human body, says Cedric F. Garland, DrPH, from the Department of Family and Preventive Medicine at the University of California, San Diego.
“When the vitamin D level is reduced, the cells of the breast epithelium don’t stick to each other, and the cell that isn’t stuck to the surrounding cells has its stem cells undergone rapid mitosis,” explains Dr. Garland.
“The cells that multiply quickest can create a cancerous clone, which can infiltrate through the basal lining. If the organism lacks vitamin D for longer, the cells will get out into lymphatics, metastasize to the brain, bone and lungs and eventually cause death.”
More on Vitamin D
The optimal amount of vitamin D is not agreed by every organization. This happens because our body creates vitamin D due to sun exposure. Age, sex, ethnicity and area of living are all factors which determine how much supplementation you need or you simply will not need at all.
We recognize two types of vitamin D: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D2 is produced by plants while D3 is produced from sun exposure by the organism in the liver and kidneys.
D3 is necessary for calcium absorption in the gut and maintains the health of teeth and bones. It is very useful in modulating the cell growth, neuromuscular and immune function, and diminish inflammation. It also fights against heart disease, chronic pain and diabetes.
The recommended amount of vitamin D by the Institute of Medicine is 600IU in majority of healthy adults and 800IU for people older than 70.
Experts suggest that the increased doses applied in cancer treatment, around 4000-10.000IU on a daily basis can harm the organs severely, especially the kidneys and cardiovascular system.
It is very important to consult with reputable and experienced doctor, oncologist or naturopath before deciding to use vitamin D for treating serious illnesses.
