Narrator: This is Science Today. A three-year UCLA study has found that prostate cancer patients who drink 8-ounce glasses of pomegranate juice per day kept PSA levels stabilized. Dr. Allan Pantuck, an associate professor of urology, says they measured the doubling time, or how long it takes for PSA levels to double, which is a signal that the cancer is progressing. The researchers found an almost four-fold increase in doubling time – going from 14 months to 54 months.
Pantuck: We see effect clinically and the next question is what is causing the effect and we're actually in the middle of taking it back into the laboratory again where we're looking at what are the molecular mechanisms or what are pathways that seem to be involved in the way pomegranate inhibits the growth of prostate cancer.
Narrator: Pantuck stresses this is not a cure for prostate cancer, but the best scenario is that patients who drink pomegranate juice regularly can ultimately slow the cancer down.
Pantuck: So that people could live out their normal life span and don't die of the prostate cancer they have.
