Researchers have found that chemotherapy may be responsible for Black women with breast cancer having a significantly higher rate of neuropathy than other races. This leads to severe damage and side effects and worse survival rates. Another effect of chemo is "chemo brain". The term "chemo brain" refers to thinking and memory problems often experienced by patients who undergo chemotherapy. For breast cancer patients battling "chemo brain," regular exercise may be a powerful prescription, a new study suggests.
It's "a growing clinical concern, "Elizabeth Salerno, an assistant professor of surgery at Washington University School of Medicine in St. Louis says. "Some patients with cancer experience memory lapses, difficulty concentrating or trouble finding the right word to finish a sentence."
In the study, Salerno's team analyzed data from 580 U.S. breast cancer patients and a control group of 363 without cancer.

During chemo, that fell to 21%, then rose to 37% six months after treatment. Rates in the control group were about 40% at all three time points.

Researchers also assessed four types of mental skills. Cancer patients who got the recommended levels of exercise before and after chemo outperformed those who never met the guidelines.
Those in the control group had similar results on the mental assessments, regardless of their exercise habits.
Significantly, results of memory and attention tests among breast cancer patients who met the activity guidelines before chemo
were similar to those of people in the control group.
However, the active cancer patients still perceived a significant decline in thinking skills, especially during chemo, according to findings published online Aug. 18 in the Journal of Clinical Oncology.
The findings lay the groundwork for future clinical trials on whether moderate to vigorous exercise can ward off "chemo brain", the authors note.
"Our findings suggest that maintaining higher levels of physical activity may indeed be important for protecting cognition in patients with breast cancer undergoing chemotherapy," Salerno says.
Tips for exercising with breast cancer
Some exercises may be dangerous for breast cancer patients depending on your condition, so it is best to consult with your doctor before you begin. You may also enlist a certified trainer or therapist that has experience working with breast cancer patients.
If you’re starting a new exercise program after breast cancer surgery, you should avoid using the arm on the side of the surgery.
Remember to go slow and rest as needed. You should also incorporate warm-ups and cool-downs into your routine. After about a month of an exercise plan, you may be able to gradually introduce exercises to your other arm.
If you feel any pain, you should adjust your workout and do smaller movements. If the pain continues, contact your doctor or physical therapist.
