What is the impact of exercise on breast cancer risk and recovery?

WESTON, Fla. ā€“ Women who exercise regularly can lower their risk of breast cancer by 10 to 20 percent, but many wonder whether itā€™s safe to exercise during and after breast cancer treatment.

As a competitive body building, 55-year old Jeanette Martin has been keenly focused on diet and exercise including a daily three-hour training routine.

ā€œIā€™ve been seriously into body building for about 6 years but always very athletic,ā€ Martin said.

Just before a national event in September 2019, she found herself facing a different challenge; breast cancer.

ā€œI knew about the diagnosis before stepping on the stage and had already committed in my mind that I was going to finish and win this competition and then address the breast cancer issue,ā€ Martin said.

For women with breast cancer, studies have shown that exercise may actually improve survival.

ā€œAlso it helps their mental health and helps them decrease anxiety and depression and maintain a healthy weight which is really important in terms of cancer recurrence,ā€ said Dr. Zeina Nahleh, with the Cleveland Clinic Weston.

Nahleh said the intensity and duration of exercise depends on how active someone was prior to their diagnosis.

ā€œGenerally we recommend patients start slowly and gently; doing aerobic exercises like just walking around the neighborhood,ā€ she said.

Martin believes her strong and competitive nature helped her through her treatment during which she continued her training routinely, though not as aggressively.

ā€œI treated it like a competition. My coaches said ā€˜listen, itā€™s breast cancer, itā€™s like prep. Take six months, handle it, beat it and move on to the next challenge,ā€™ and thatā€™s exactly what I did,ā€ Martin said.

Regardless of someoneā€™s personal fitness levels, breast cancer specialists said patients do need to consult with their treatment team to make sure the activity doesnā€™t compromise their recovery.
