Using a sample 14,641 male, a team of researchers was led by J. Michael Gaziano, MD, MPH, from the Department of Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, Massachusetts. The study found that multivitamins reduce the chance of developing cancer by 8%. The study titled “Multivitamins in the Prevention of Cancer in Men, The Physicians' Health Study II Randomized Controlled Trial” is being published online in the Journal of the American Medical Association.
All samples in the study were men aged 50 or older with occupation as doctors. They all were free of cancer. Researchers randomly selected samples and divided the samples into two groups. For the first group, researchers gave them monthly packets of Centrum Silver produced by Pfizer Inc. For the second group, researchers gave them fake multivitamins (placebo). The study started in 1997 and was conducted for duration of 10 years.
The results showed that there were 2,669 new cancers among all men in the samples including 1,373 men with prostate cancer and 210 men with colorectal cancer. Based on 1,000 men in the samples per year, researchers found 17 cancers among multivitamin users. On the other hand, for every 1,000 men in the samples per year, 18.3 cases of cancers among men taking fake multivitamins (placebo).
