Evaluation of the Concept "Can Do" Versus "Do Do" in Patients With Breast Cancer

Breast cancer occurs as a result of uncontrolled proliferation of cells in the breast tissue. Breast cancer is the most common type of cancer among women worldwide and is an important problem that threatens women's lives. The incidence rate has reached approximately 16 Breast cancer treatment consists of local and systemic therapies. While local treatments include surgery and radiotherapy, systemic treatments, which are administered in two different ways, namely adjuvant and neoadjuvant systemic treatments, consist of chemotherapy, hormone therapy and targeted biological therapies. Although the treatment options for breast cancer are increasing day by day, there are many complications during and after treatment. These complications negatively affect functionality and quality of life.

Thanks to the increasing treatment possibilities with the developing technology in recent years, the majority of patients show good functional recovery after breast cancer. However, it has been reported that treatments negatively affect the functional capacity of the upper extremities, daily life, work and social activities and decrease the quality of life. Many side effects are observed in patients after breast cancer treatment. Therefore, there are various rehabilitation needs. Side effects vary from person to person. Therefore, the rehabilitation program to be applied should be personalized. Commonly reported side effects of the disease or treatments include pain, lymphedema, fatigue and depression. In addition, psychosocial consequences and psychological distress, such as reduced health-related quality of life and reduced social contacts, as well as difficulties in maintaining functional activities and life roles, have been reported. As a result, breast cancer patients may have physical, psychological, social and existential rehabilitation needs.

Exercise is an effective non-pharmacologic treatment method in cancer patients. Exercise also has therapeutic properties in cancer-related fatigue. Increased physical activity has been reported to improve psychological recovery and physical well-being in cancer patients. Aerobic exercise has been proven to reduce cancer-related fatigue as a result of studies. It has also been reported that supervised exercise during chemotherapy or radiotherapy treatments both increases the effectiveness of the treatment and reduces the side effects that may occur. In addition, resistance exercises significantly reduce cancer-related fatigue. There is evidence that there is a strong relationship between the risk of breast cancer and physical activity level. Exercise training is an important physiotherapy and rehabilitation approach in breast cancer survivors. According to randomized controlled trials on the outcomes of exercise modalities in women with breast cancer, women who exercise have improved survival rates. Physical and psychological conditions such as fatigue, pain, anxiety, depression and decreased functional capacity reduce patients' quality of life. Exercise interventions during or after treatment have been reported to improve musculoskeletal performance, cardiorespiratory fitness, body awareness, and psychological status in breast cancer. Previous studies have also reported that exercise training programs to be applied during or after cancer treatment in cancer patients improve quality of life. It has been reported that mind-body togetherness exercises such as aerobic, resistance, stretching, yoga, and Tai Chi in breast cancer patients improve quality of life and general and mental health, and have a positive effect on of the maximal oxygen uptake (VO2 max) , and provide significant improvements in self-esteem and attitude towards life. In addition, exercise training alleviates symptoms of depression and anxiety in breast cancer survivors. In addition to reducing body mass index (BMI) and causing significant increases in lean mass, exercise also increases muscle strength in the intervention groups. Furthermore, the serum concentration of some physiological markers, such as insulin, insulin-like growth factor (IGF-II) and insulin-like growth factor binding protein (IGFBP-1), is significantly reduced after the exercise intervention. Physical activity has been shown to improve the symptom of fatigue.

The type, intensity, intensity and duration of the exercise to be applied differ from person to person. Exercise intervention is safe both during and after systemic treatments. Therefore, exercise intervention should be prescribed to breast cancer patients and they should be encouraged to maintain their established exercise habits or adopt a correct type of exercise.

The most widely accepted exercise regimen for breast cancer patients is about 150 minutes of moderate to vigorous intensity aerobic exercise per week. However, only 30% to 47% of breast cancer survivors are reported to adhere to the recommended exercise programs. Furthermore, aerobic exercise, strengthening exercises or body-mind exercises have a significant impact on side effects after cancer treatments. Aerobic and resistance exercises reduce physical and psychosocial problems associated with cancer and cancer treatment. Breast cancer survivors are also recommended mindfulness, yoga or body-mind exercises to feel better and more relaxed. Breathing exercises during physical activity are important for relaxation.
