Physical exercise post-treatment in breast cancer: a longitudinal study

The prevalence of breast cancer has been progressively rising as a result of advancements in anti-cancer therapies, however, these patients also experience a variety of long-term adverse effects from their illness and treatments. The current study sought to determine how an exercise training intervention influenced physical and mental health indices in breast cancer patients. A total of 30 female breast cancer patients (aged 42.81 ± 3.31 years, body mass index (BMI) 26.87 ± 0.59 kg/m2, and waist circumference 97.61 ± 1.94 cm) engaged in 12 weekly exercise regimens twice weekly that comprised aerobic, resistance, and flexibility activities. The exercise intervention improved participants' cardiorespiratory fitness, BMI, waist circumference, and muscle function, including sitting to standing, sit-ups, and push-ups. It also showed positive results for post-traumatic stress disorder (PTSD) symptoms, self-reported fatigue, quality of life, and physical, cognitive, and emotional functioning (p < 0.001). In conclusion, our results imply that the advantages of an exercise training program may help breast cancer patients lessen the negative impacts of treatment-related factors on physical performance, overall quality of life, and mental health.
