Being physically active may help with the ongoing pain that people with cancer often experience, according to Aussie researchers. The team analysed information from 10,651 with past cancer diagnosis as well as 51,439 adults without a history of cancer, including information about how much pain they felt on average and their usual physical activity. For both groups of people, the team found more physical activity was linked with lower pain intensity. Among those with a past cancer diagnosis, those exceeding physical activity guidelines were 16% less likely to report moderate-to-severe pain, compared to those who failed to meet those guidelines. Those who were consistently active or became active in older adulthood also reported less pain than those who remained inactive. While this kind of research cannot establish cause-and-effect, the results may indicate exercise may reduce cancer-related pain, just as it does for other types of pain studied in the past, the authors say.

Does physical activity lessen pain intensity for cancer survivors?

Study shows that higher levels of physical activity are linked with less pain, and to a similar extent in adults with and without a history of cancer.

People who have had cancer often experience ongoing pain, but a new study reveals that being physically active may help lessen its intensity. The study is published by Wiley online in CANCER, a peer-reviewed journal of the American Cancer Society.

Although physical activity has been shown to lessen various types of pain, its effects on cancer-related pain are unclear. To investigate, a team led by senior author Erika Rees-Punia, PhD, MPH, of the American Cancer Society, and first author Christopher T.V. Swain, PhD, of the University of Melbourne, in Australia, analyzed information pertaining to 51,439 adults without a history of cancer and 10,651 adults with a past cancer diagnosis. Participants were asked, “How would you rate your pain on average,” with responses ranging from 0 (no pain) to 10 (worst pain imaginable). Participants were also asked about their usual physical activity.

U.S. guidelines recommend 150 minutes (2 hours 30 minutes) to 300 minutes (5 hours) a week of moderate-intensity, or 75 minutes (1 hour 15 minutes) to 150 minutes (2 hours 30 minutes) a week of vigorous-intensity aerobic physical activity.

Based on participants’ responses, the investigators found that, for individuals who had cancer in the past as well as for those without a history of cancer, more physical activity was linked with lower pain intensity. The extent of the association was similar for both groups of individuals, indicating that exercise may reduce cancer-related pain just as it does for other types of pain that have been studied in the past.

Among participants with a past cancer diagnosis, those exceeding physical activity guidelines were 16% less likely to report moderate-to-severe pain compared to those who failed to meet physical activity guidelines. Also, compared with people who remained inactive, those who were consistently active or became active in older adulthood reported less pain.

“It may feel counterintuitive to some, but physical activity is an effective, non-pharmacologic option for reducing many types of pain. As our study suggests, this may include pain associated with cancer and its treatments,” said Dr. Rees-Punia.
