Why Breast Cancer Survivors Should Exercise?

According to a new research, excessive stress can lead to memory problems among breast cancer survivors, but exercise can help.

A study’s lead author, Siobhan Phillips, an assistant professor of preventive medicine at Northwestern University Feinberg School of Medicine in Chicago said, “We found moderate to vigorous physical activity actually benefits women psychologically and that, in turn, helps their memory.”

Post-cancer memory issues are often attributed to chemotherapy or radiation treatments, known as “chemo brain.” However, the new study findings suggest “these self-reported memory problems may be in part emotionally related,” Phillips said in a university news release.

He explained, “These women are frightened, stressed, fatigued, tapped out emotionally and have low self-confidence, which can be very mentally taxing and can lead to perceived memory problems.”

The researchers examined self-reported memory and exercise data collected from more than 1,800 breast cancer survivors, 362 of whom wore devices called “accelerometers” to track their movement. In both groups, moderate or vigorous physical activity — such as brisk walking, biking, jogging or engaging in exercise classes — was found to reduce stress and fatigue. This has psychological benefits and leads to better memory, the researchers said.

Whereas the study didn’t establish a direct cause-and-effect relationship, greater levels of physical activity were also linked to higher levels of self-confidence and less distress. These improvements were also associated with fewer perceived memory problems, the study authors added.
