Dr. Kerry Courneya discusses the CHALLENGE trial, the first study to show exercise improved survival after cancer treatment.

The CHALLENGE trial found that a three-year, structured exercise program after chemotherapy for stage III colon cancer reduced the risk of the cancer coming back (recurrence risk) and also led to people living longer overall. Dr. Kerry Courneya, the lead researcher, thinks the results can be applied to people with other types of cancer, including breast cancer.

Listen to the episode to hear Dr. Courneya explain:

  • why the study asked people to exercise for three years
  • why he thinks the results may spur insurance companies to cover exercise-related costs, like equipment and gym memberships
  • the reasons why the results also could apply to people diagnosed with breast cancer
