Radiation therapy is a form of therapy utilising high energy radiation to target and destroy
cancer cells. The specific type of radiotherapy is selected based on the type of cancer a
client has, how advanced the cancer growth is and the overall health of the client undergoing
therapy. Emerging studies have examined how exercise can enhance the effectiveness of
radiotherapy to maximise efficacy against cancer progression.
Here are a couple of ways exercise can help.
Exercise improves Oxygen Supply to Tumours . . . . . Tumours don’t like that!
Tumour hypoxia refers to a state where tumour cells experience insufficient oxygen supply
due to rapid growth and impaired blood vessel function. This hypoxia is associated with
increased cancer progression, metastasis, and resistance to treatments.
Regular exercise can enhance cardiovascular health, leading to better blood circulation.
Improved blood flow means more oxygen can reach the tumour. Improved blood flow and
oxygenation to the tumour site can make cancer cells significantly more susceptible to
radiation therapy as well as other forms of therapy like chemotherapy or immunotherapy.
Exercise boosts immunity . . . . . .That makes it tough for Tumours!
Physical activity and exercise stimulate the release of molecules called myokines from
muscle fibres during activity. Certain myokines can stimulate the production and activation of
various immune cells, such as natural killer (NK) cells and T-cells, which play crucial roles in
identifying and attacking cancer cells. Some myokines can also help reduce chronic
inflammation, creating a more favourable environment for immune cells to function
effectively against tumours.
Symptom Management and Quality of Life
The benefits of exercise extend beyond boosting efficacy of radiotherapy and other cancer
treatments. Physical activity can significantly boost energy levels to reduce the persistent
fatigue often experienced throughout radiation therapy courses. Maintaining or improving
physical function can also reduce muscle loss, or weight loss typically experienced with
treatment. Regular exercise can also improve sleep quality, mood and pain levels for
patients undergoing cancer treatment.
