Consistent exercise associated with lower risk of colon cancer death

03.01.2011
Consistent exercise is associated with a lower risk of dying from colon cancer, according to a new study led by researchers at the Siteman Cancer Center at Washington University School of Medicine and Barnes-Jewish Hospital in St. Louis. The study is among the first to show that physical activity can make the disease less deadly.

The Washington University researchers worked with colleagues from the American Cancer Society and examined data from the American Cancer Society Prevention Study II (CPS II) to look at whether changes in physical activity influenced either the incidence of colon cancer diagnosis or the risk of death from the disease.

The CPS II study included more than 150,000 men and women. To determine how exercise affected colon cancer, the researchers compared their levels of physical activity between 1982 and 1997, and linked those activity levels both to the number of colon cancer diagnoses between 1998 and 2005, and to the number of colon cancer deaths that occurred between 1998 and 2006. It turned out that those who exercised consistently for at least 10 years had the lowest risk of colon cancer death.

“People who were consistently active over the course of their adulthood had a lower risk of death from colon cancer than those who were sedentary,” says first author Kathleen Y. Wolin, ScD. “People often wonder around the start of a new year whether exercise really will help them stay healthy or whether it’s already too late. It’s never too late to start exercising, but it’s also never too early to start being active. That’s the message we hope people will take away from this study.”

Wolin
Wolin, assistant professor of surgery in the Division of Public Health Sciences, says the benefits of starting an exercise program include not just preventing colon cancer and death from the disease, but also reduced risk of heart disease, diabetes and other cancers.

She says the greatest benefits seem to accrue in those who have exercised for the largest percentage of their lives. But it isn’t necessary to run marathons or to work out for many hours every day.

“You get enormous ‘bang for the buck,’” she says. “You go for a 30-minute walk every day, and you’re going to reduce your risk of a number of diseases. And in addition, our research has also shown that you feel better, physically and mentally, so you’re able to function better.”

And physical activity even can be beneficial after a cancer diagnosis already has been made.

“There is evidence that being physically active can reduce the risk of recurrence and death following a cancer diagnosis,” Wolin says. “So even those who haven’t been physically active can begin exercising after their diagnosis and see some real benefits as well.”

This work was supported by the National Institutes of Health and by the American Cancer Society.

Washington University School of Medicine’s 2,100 employed and volunteer faculty physicians also are the medical staff of Barnes-Jewish and St. Louis Children's hospitals. The School of Medicine is one of the leading medical research, teaching and patient care institutions in the nation, currently ranked fourth in the nation by U.S. News & World Report. Through its affiliations with Barnes-Jewish and St. Louis Children's hospitals, the School of Medicine is linked to BJC HealthCare.

Siteman Cancer Center encompasses the combined cancer-related programs of Washington University and Barnes-Jewish Hospital. It is the only cancer center within 250 miles of St. Louis designated as a Comprehensive Cancer Center by the National Cancer Institute.

It has locations at Washington University Medical Center on South Kingshighway, at Barnes-Jewish West County Hospital, Barnes-Jewish St. Peters Hospital and has plans to open a facility in south St. Louis County in 2012.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
