Study finds vitamin D does not protect against most cancers
QIMR Berghofer researchers have found vitamin D levels do not influence a person’s risk of developing most common cancers, suggesting that widespread use of vitamin D supplements is unlikely to prevent cancer.
The study used genetic markers of vitamin D to examine the relationship between vitamin D and endometrial, ovarian, oesophageal, prostate, pancreatic and lung cancers, as well as neuroblastoma, melanoma, and basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin.
While they did not find a link between most of the cancers, the researchers did confirm previous research that found women who were genetically predisposed to having higher levels of vitamin D had a slightly lower risk of developing ovarian cancer.

An Australian randomised controlled trial of vitamin D supplements, led by QIMR Berghofer Medical Research Institute has found they do not protect most people from developing colds, flu and other acute respiratory infections. The trial, which is the largest of its kind to study the relationship between vitamin D and respiratory infection to date did show, however, that the supplements may shorten the length of infection slightly and help ease the severity of those illnesses. The study results have been published this week in the scientific journal The Lancet Diabetes and Endocrinology. The researchers analysed self-reported health data from 16,000 Australians aged between 60 and 84, who participated in the QIMR Berghofer Medical Research Institute-led D-Health Trial.
