When facing a cancer diagnosis, patients often look for every possible way to improve their treatment. One common question is whether adding physical exercise to chemotherapy can help shrink tumors more effectively. Researchers looked at data from 504 patients with solid tumors, including breast, esophageal, gastric, and rectal cancers, to find out.
The analysis found that for most patients, adding aerobic or resistance exercise did not significantly change the rate of pathologic complete response. This is the measure of how well chemotherapy clears the tumor. However, the data did show a potential trend for a specific type of breast cancer, but the evidence for this is not very strong.
It is important to keep these findings in perspective. Because the study relied on a small number of reports, the overall certainty of the evidence is low. While the data suggests a possible link for some breast cancer patients, it is not enough to confirm a clear benefit for everyone. Patients should talk to their doctors about how exercise fits into their specific care plan.
