How can Moving More help you? What the research says

How does Moving More impact your cancer outcomes, affect your quality of life, or impact your body terrain? We present the evidence.

For information and guidance on adding physical activity to your life, see our main page on Moving More ›

We strongly emphasize that Moving More by itself will not prevent, cure or control cancer or prevent recurrence. Like every other therapy or approach included on this website, Moving More is one component of an individualized integrative plan rather than a stand-alone therapy.

We summarize the clinical evidence for each medical benefit here. We begin with our assessment of the strength of evidence within each category, followed by a brief summary of individual studies or reviews of several studies. In assessing the strength of evidence, we consider the study design, number of participants, and the size of the treatment effect (how much outcomes changed with treatment).

Improving treatment outcomes

Is Moving More linked to improved survival? Is it linked to less cancer growth or metastasis? Does it enhance the anticancer action of other treatments or therapies? We present the evidence.

The relationship between activity and survival becomes complex as people have more advanced disease or illness. People who are very ill may not be able to move much at all, but we wouldn’t conclude that more activity would delay death. However, evidence shows that even with advanced cancer, increasing activity within your limits is linked to better survival.

Similarly, pushing yourself to high levels of activity during treatment may not be wise. Guidelines encourage you to be as active as available given your situation. Follow your doctor’s recommendations, and also listen to your body’s need for rest.

Cancer as a whole

Good evidencesignificant effects in one large or several mid-sized and well-designed clinical studies (RCTs with an appropriate placebo or other strong comparison control or observational studies that control for confounds (this is the CancerChoices definition; other researchers and studies may define this differently) of moderately better survival among people with higher activity levels after diagnosis

Modest evidenceat least three small but well-designed RCTs, or one or more well-designed, mid-sized clinical studies of reasonably good quality (RCTs or observational studies), or several small studies aggregated into a meta-analysis found no effect (this is the CancerChoices definition; other researchers and studies may define this differently) of possibly better chemotherapy completion rates, but no evidenceoverall, one or more studies did not demonstrate that a treatment or intervention led to an expected outcome; this does not always mean that there is no effect in clinical practice, but that the studies may have been underpowered (too few participants) or poorly designed. Larger, well-designed studies provide more confidence in making assessments. of improved response rate or survival among people with cancer participating in aerobic exercise during chemotherapy

CancerChoices provides information about integrative in cancer care, a patient-centered approach combining the best of conventional care, self care and evidence-informed complementary care in an integrated plan cancer care. We review complementaryin cancer care, complementary care involves the use of therapies intended to enhance or add to standard conventional treatments; examples include supplements, mind-body approaches such as yoga or psychosocial therapy, and acupuncture therapies and self-care lifestyle actions and behaviors that may impact cancer outcomes; examples include eating health-promoting foods, limiting alcohol, increasing physical activity, and managing stress practices to help patients and professionals explore and integrate the best combination of conventionalthe cancer care offered by conventionally trained physicians and most hospitals; examples are chemotherapy, surgery, and radiotherapy and complementary therapies and practices for each person.
