Study: Supplements Increase Prostate Cancer Risk

Depending upon whether men have a lot or little of the mineral selenium in their bodies, taking large doses of either selenium or vitamin E can almost double the risk of an aggressive form of prostate cancer, suggests a new study. Vitamin E supplements increase all prostate cancer risk among men with low levels; selenium supplements increase risk among those with high levels.Composition With Variety Of Drug Pills And Dietary Supplements

The study was published in the Journal of the National Cancer Institute. Its findings, somewhat unexpected, adds to a complex body of research on supplements and cancer risk.

AICR currently recommends not relying on supplements to prevent cancer; instead, taking in your nutrients, phytochemicals and other cancer-fighting compounds from food.

The study continues the findings from a large trial that was stopped back in 2008. Called the Selenium and Vitamin E Cancer Prevention Trial (SELECT), the study was investigating whether selenium and/or vitamin E could lower prostate cancer risk. Both are essential for good health and have antioxidant activity. Continue reading


Halving Cancer Death with AICR Recommendations for Prevention

Eating mostly fruits, vegetables and other plant foods, staying a healthy weight and exercising are among AICR’s recommendations shown to reduce the risk of developing cancer.

Holding HandsNow a new study suggests that healthy people who follow at least five of AICR’s Recommendations have a lower risk of dying from cancer by more than half compared to those who don’t follow any. And the lower risk was seen with meeting just one recommendation, getting lower for each additional recommendation followed.

The study was published in the February issue of Cancer Causes & Control.

“We found that meeting the AICR recommendations for body weight, diet, and physical activity is associated with lower cancer mortality,” says lead author Theresa Hastert, an epidemiologist at University of Michigan School of Public Health who conducted the study while at the Fred Hutchinson Cancer Research Center and the University of Washington. “Although the benefits are greatest for people who meet the most recommendations, even meeting one or two can be protective.” Continue reading


Just How Many Cancers Are Preventable?

On Tuesday, World Cancer Day, the preventability of cancer made big headlines around the world. Here at AICR, we were pleased to see that.

After all, we’ve dedicated ourselves to funding and analyzing research, which shows we can prevent one-third of the most common cancers — over 374,000 U.S. cancer cases every year — by changes to our diet, physical activity and weight.

But you may have seen headlines with different numbers from the World Health Organization (WHO) saying that one half of all cancers are preventable. We heard from some of you who were confused because AICR says we can cut the number of cancers by one third.

So, which is it? How many cancers don’t have to happen: one-third, or one-half? Who’s right, AICR or WHO?

The answer, of course, is that we both are. Continue reading
