Exercise and Breast Cancer: One Woman’s Story

By Joan Pagano - September 30, 2011

"I've always exercised, but I increased the amount and type of exercise after being diagnosed in May five years ago," answered Margo Kornfeld, SHARE member and fitness enthusiast, when I asked her to tell me about her exercise regimen during treatment. She went on to explain that she's a recreational cyclist and found it to be very therapeutic – plus wearing a helmet covered up her baldness!

Margo added weight training and yoga into her program and then started to focus on endurance sports. After she finished her treatments, she bought a road bike in celebration and decided to do a century ride (100 miles) to raise money for other cancer victims. She also started running and has completed half-marathons (13 miles).

Her instincts proved she was on the right track! When she had the opportunity to ask Dr. Larry Norton what she could do to prevent a recurrence he told her, "It's not about diet or exercise, but about athleticism and getting the endorphins going." Margo had severe asthma as a child and was never an athlete, so getting to a high level of endurance sports was truly transformational.

In her practical approach to managing the side effects of treatment, Margo said that while exercise prior and during chemo kept her strong, when she had a low energy day she would take the day off and rest. She shares her personal, positive mind-set for getting through treatment: "Think about your future beyond chemo. Chemo's not the end-game. The end-game is living a healthy life afterward… You want your body to live in a 'neighborhood' where it will thrive and be nurtured." Margo recommends that you build your body up to sustain chemo, help prevent recurrence and have a healthy future.
