Large-scale analysis published in JAMA Network Open concludes that moderate-to-vigorous physical activity after diagnosis substantially reduces cancer-related death, even for previously inactive patients.

A major new study published Feb. 17 in JAMA Network Open concludes that regular physical activity after a cancer diagnosis is associated with significantly lower risk of death across seven types of cancer, strengthening the case for exercise as a core component of post-diagnosis care.
The large-scale analysis examined data from more than 17,000 survivors of bladder, endometrial, kidney, lung, oral cavity, ovarian and rectal cancers. Researchers found that moderate-to-vigorous exercise following diagnosis was consistently linked to improved survival outcomes, with some cancers showing mortality reductions exceeding 60 percent among those meeting recommended activity levels.
The study pooled decades of data from six long-running national health cohorts, including the Nurses’ Health Study and the Health Professionals Follow-Up Study. The final cohort included 17,141 adults who had survived one of the seven targeted cancers. Participants reported their leisure-time physical activity both before and after diagnosis, with post-diagnosis activity assessed an average of 2.8 years later to avoid capturing the immediate treatment phase, when inactivity is common.
Physical activity levels were measured in metabolic equivalent task hours per week (MET-h/wk), a standard unit used to quantify energy expenditure. Public health guidelines recommend between 7.5 and 15 MET-h/wk, equivalent to 150 to 300 minutes of moderate exercise such as brisk walking.
Researchers tracked cancer-related mortality over an average follow-up period of nearly 11 years. Statistical models accounted for age, smoking status, cancer stage, treatment type and other variables in order to isolate the effect of physical activity.
The results showed that for survivors of bladder, endometrial, lung and ovarian cancers, even modest amounts of moderate-to-vigorous activity were associated with lower risk of cancer-related death. Bladder cancer survivors who engaged in some activity experienced a 33 percent lower mortality risk compared to inactive individuals. Meeting recommended activity guidelines was linked to a 60 percent lower risk of death for endometrial cancer and up to a 62 percent reduction for lung cancer.
For oral and rectal cancers, the most pronounced survival benefits were observed at higher levels of activity. Oral cancer survivors who exercised at more than double the recommended guideline levels experienced a 61 percent lower risk of death. Rectal cancer survivors reaching similar higher activity benchmarks saw a 43 percent reduction in mortality risk.
The association for kidney cancer trended toward benefit but did not reach statistical significance in this analysis.
One of the study’s key findings was that patients who were inactive before their diagnosis still experienced meaningful survival gains if they became active afterward. Lung and rectal cancer survivors who adopted regular physical activity post-diagnosis demonstrated significant reductions in mortality risk, underscoring that benefits are not limited to lifelong exercisers.
Experts say the practical implications are straightforward. Exercise physiologists recommend beginning with short “microwalks,” such as five-minute or 500-step walks throughout the day to reduce sedentary time. These can gradually build toward the widely recommended target of 150 minutes of moderate-intensity activity or 75 minutes of vigorous activity per week.
Moderate intensity can be estimated by subtracting one’s age from 220 and multiplying by 0.7 to determine a target heart rate. Vigorous intensity corresponds to approximately 0.8 of the age-adjusted maximum heart rate and typically makes sustained conversation difficult.
Physical therapists advise cancer survivors to start slowly, monitor fatigue and incorporate strength training twice weekly as tolerated. Activities such as walking, cycling, swimming, yoga or dancing may help improve adherence when aligned with personal preference.
BrightU.AI’s Enoch stated that cancer survival involves supporting the body’s inherent capacity to overcome biological dysregulation. “Cancer survival is fundamentally about hope, as it is not an automatic death sentence,” he said, adding that understanding cancer as a biological process allows individuals to focus on strengthening overall resilience.
Researchers conclude that the findings elevate exercise from a general wellness recommendation to an evidence-based intervention with measurable survival impact across multiple cancer types. As oncologists continue refining treatment protocols, the data suggest that structured physical activity may warrant formal integration into standard cancer care strategies.
