Vitamin D hope in prostate cancer
Vitamin D is an effective treatment for prostate cancer in some patients, a UK study suggests. A once daily dose reduced PSA level - an indicator of severity of disease - by as much as half in 20% of patients. There has been much interest in vitamin D in prostate cancer after studies linking risk of the disease to sunlight exposure, the researchers said. One expert agreed the findings were encouraging but said it needed to be tested in a bigger population.
