The study authors found that the cell growth and radio-sensitivity of the malignant tumor cells were not affected by any of the supplements, but two of the supplements inhibited the growth rate of the normal prostate cell lines while a third supplement also increased the cellular radio-sensitivity of some normal cell lines by inhibiting DNA repair.
"Cancer patients turn to supplements to aid in their treatments for a variety of reasons, but this study proves that what some patients believe is helping them may actually be harming them," Brian Marples, Ph.D., senior author of the study and a radio-biologist at William Beaumont Hospital and clinical research professor at Oakland University William Beaumont School of Medicine, said. "It is very important for all patients to discuss any type of supplement they may be taking with their physician and especially important for prostate cancer patients receiving radiation therapy as this study shows that it may be negatively affecting the effectiveness of their treatments."
