What do cigarettes, sun-baking and paint fumes have in common? They all cause cancer, according to the World Health Organisation.
With the list of things we shouldn’t do growing each year, it can feel like there’s not much we can proactively do to prevent cancer.
But Dr Brigid Lynch, senior research fellow at The Cancer Council and National Breast Cancer Foundation fund recipient believes exercise can play a significant role in both breast cancer prevention and treatment.
“Exercise appeals on so many levels,” she told The New Daily. “It’s freely available, it’s simple and it can make a big difference.”
According to Dr Lynch, Australians are often unaware of the potential benefits her research continues to uncover.
Prevention and treatment
Dr Lynch’s research has found regular exercise can improve our immune systems, vitamin D levels and our insulin resistance, leading to a decreased risk of breast cancer and colon cancer in particular. There was also some evidence it can help prevent lung and prostate cancers.
Her research records the amount of exercise women are doing and compare that with their risk of getting breast cancer, based on their BMI, waist circumference and insulin.
Of course, it shouldn’t come as much of a surprise that exercise can help prevent cancer – after all, it’s been touted as helping our brain function, skin, circulation, ageing process and preventing chronic disease. But helping cure cancer is another business.
“It’s counterintuitive, because chemotherapy causes lethargy and fatigue, but patients who exercise more actually suffer less fatigue,” said Dr Lynch, who claimed doctors had noticed patients who regularly exercised were more able to withstand the nasty side affects of chemotherapy and complete the course.
Vigorous is best
Dr Lynch said we should be aiming for an hour of moderate to vigorous exercise each day, and there was no reason women with breast cancer couldn’t do high intensity exercise if OK’d by their doctor.
“More is better, but it’s good to start small,” she said, and suggested starting with a brisk walk around the block and building up from there.
Dr Lynch said there had been a number of studies linking the benefits of exercise to cancer prevention and treatment, but it was important for researchers to better understand the biological effects of exercise.
“We need to replicate the study in different countries,” she said, adding that the researchers also want to tease out the ideal exercise for cancer patients.
“We know so much about negative behaviours like smoking and alcohol, but not enough about the positive ones.”
