How physically active are women undergoing radiation therapy for breast cancer? A cross-sectional study of patterns,...

Breast cancer is the most common cancer worldwide, with 2.3 million diagnoses each year. Treatment options like surgery, chemotherapy, and radiation therapy (RT) can cause side effects and reduce quality of life. In Australia, the 5-year survival rate for breast cancer is 92 %, indicating a need for effective support strategies during treatment. Physical activity (PA) has proven benefits for both physical and emotional health and can prevent chronic illnesses. This study explores the patterns of PA, attitudes, and support needs of women undergoing RT for breast cancer.

An online survey was circulated among radiation oncology sites in Australia's Capital Territory, New South Wales, and Queensland. The survey included 70 questions about well-being, PA patterns, and support needs.

Ninety women participated in the study, most aged 45 to 74, who had a lumpectomy before adjuvant treatment. During RT, 56 % reported engaging in less PA than desired, and 61 % experienced decreased attentiveness in work and daily activities due to the illness's impact on their mental health. On average, participants briskly walked four times a week both before diagnosis and during RT. While vigorous activities increased from once a week before diagnosis to three times a week during RT. Additionally, 30 % felt they received inadequate information about PA during RT.

This study identified the PA habits of women with breast cancer receiving RT and the need for support in this area. PA could enhance patient well-being during cancer treatment; however, further investigation is required to identify appropriate methods for implementing PA interventions during RT.

Despite the increasing evidence supporting the benefits of PA in cancer care, a significant knowledge gap persists among oncology practitioners providing PA guidance to patients. This presents an opportunity for implementing training in this area.
