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.
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
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.
Now 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
Research already shows that being active can reduce the risk of developing several cancers. Now comes a study that suggests for men, taking that brisk daily walk after a cancer diagnosis may lengthen your life.
The study was published in the Journal of Physical Activity and Health, and it adds to a growing body of research suggesting that exercise can have significant health benefits for cancer survivors.
“The main take away message is that physical activity improves survival in men with cancer, says I-Min Lee, MD, ScD, an epidemiologist at the Harvard School of Public Health and lead author of the study.
”There have been previous studies, examining survival in breast, prostate, and colorectal cancer patients, showing similar findings. Our study included not only survivors of these cancers, but of other cancers “
For the study, Lee and her colleagues looked at data collected in 1988 from a group of about 1,000 male cancer survivors. On average the men had been diagnosed six years previously – in 1982. In 1988 the men reported on their activity habits. They also answered questions about their weight, smoking habits, alcohol consumption, and what foods they ate. The data was updated five years later. Continue reading
