Finally, they examined whether, statistically, sitting more upped the likelihood of dying from cancer. And it did, substantially. The men and women in the group that had spent the most hours sitting were 82 percent more likely to have died from cancer during the study’s follow-up period than those in the group that had sat the least. This association held true when the researchers controlled for people’s ages, weight, gender, health, smoking status, education, geographic location and other factors.

In other words, sitting for hours increased the likelihood that someone eventually would die of cancer, even if he or she otherwise was well.

But the scientists unearthed a more-encouraging finding when they statistically modeled how those risks might change if someone, theoretically, started moving more. In those models, for every 30 minutes that someone exercised instead of continuing to sit, the risk of later dying from cancer fell by 31 percent. Even if someone did not formally work out, but substituted at least 10 minutes of his or her usual sitting time with gentle strolling, housework, gardening or other light-intensity activities, the risk of dying from cancer fell by about 8 percent.

Taken as a whole, these data suggest that “even a small amount of extra physical activity, no matter how light it might be, can have benefits for cancer survival,” says Dr. Susan Gilchrist, a cardiologist at the MD Anderson Cancer Center who works with cancer patients and led the new study.

The study has many limitations, though. It looked at cancer mortality, not the risk of developing the disease in the first place, and lumped all cancer types together. Perhaps most important, this kind of prospective study is not a randomized experiment and cannot tell us that sitting more causes increased cancer mortality, only that the two are linked. It also offers no clues about how sitting raises that risks, and whether inactivity directly changes our bodies or if other factors, including what we eat or drink while seated, influence how sitting raises our risk of dying from cancer.

Dr. Gilchrist says that she and her colleagues hope to examine some of those issues in future studies. But even with the caveats, she thinks that the data from this study should be rousing.

“The tangible takeaway is that we can tell people they do not have to go out and run a marathon” to potentially reduce their risk of dying from cancer, she says. “It looks like just getting up and walking around the living room for a few minutes every hour or so could make a meaningful difference.”
