Countries that have more sunlight have lower incidence of breast cancer, therefore providing evidence that the disease might be curbed by the sun's naturally-occuring vitamin D, says a recent study.
Earlier studies have already linked vitamin D to hindering cancer cell division in lab experiments which ultimately prevents tumours from growing.
Vitamin D is also found in assorted fish and dairy products and is also known to boost genetic activity in some genes while decreasing others.
Gene p21 plays a crucial role in controlling cell cycles and is known to boost its regeneration efforts with high vitamin D levels.
The decrease of bone metastases among cancer patients seem to parallel the break-down of vitamin D in the breast cancer patient.
Published in the Journal of Clinical Pathology, the study's conclusion is clear that more work is needed to determine what the exact cause and effect relationship is and whether Vitamin D treatment will be effective.
