Overview of Breast Cancer
Breast cancer is the most common malignancy in women, with adenocarcinomas being the most common form of breast cancer. These carcinomas can affect breast ductal tissues and axillary lymph nodes, leading to malignancy. Treatment is based on the staging of the carcinoma and the client's hormonal sensitivity. Treatments usually include a combination of surgery, radiation and chemotherapies, and hormonal drugs. Clients become deconditioned due to the disease process and treatment programs that produce persistent fatigue and decreased tolerance to physical activities.1,2
Benefits of Exercise Programs for Clients With Breast Cancer
|Improved cardiorespiratory fitness ||Improved physical functioning |
|Improved quality of life ||Reduced fatigue |
|Improved self-esteem ||Improved rate of completion for chemotherapies |
Comorbidities to Consider
Keys to Examination of Clients
Determine clients' physiological status and preparedness for engaging in the physical activities by assessing results of blood tests for platelet levels, hemoglobin, and white blood cell levels.
Clients undergoing chemotherapy may not be able to participate in aerobic activities when hemoglobin levels are <10 g/dL and platelet counts are <50,000/mm3.
Clients who have undergone surgical excisions and other procedures may have limited mobility due to slowed wound healing and fibrotic scar formations.
Recommended Baseline Testing of Fitness Levels
Use a walking or a cycle ergometer test to assess tolerance for exercise and to predict a Vo2 maximum.
Assess clients' mobility and flexibility before clients begin exercise activities. Clients who have undergone surgical removal of lymph nodes should have the upper extremities assessed for mobility; volumetric measures should be taken to assess for changes in edema levels.
Upper- and lower-extremity strength can be assessed using hand weights, resistance tubing, or weight-lifting machines.
Quality-of-life measures and fatigue levels can be assessed by the Functional Assessment of Cancer Therapy for breast cancer.4,5
Type: Walking, cycling, aquatics, and resistance training1,2, 6,7,8
Intensity: Start at 60% of Vo2 maximum2,6
Frequency: Three times per week
Exercise sessions can be used on days alternating with chemotherapy treatments. This allows clients to adapt to the exercise program while maintaining tolerance to adjuvant therapies for breast cancer. Yoga has been used to address persistent fatigue and emotional well-being.9 Progressions of aerobic activities are recommended for up to 80% of Vo2 maximum for 45 minutes, five times per week.1,...
