This study investigates how chemotherapy affects the heart, exercise ability, and fatigue in women with breast cancer compared to women without cancer. Breast cancer is a disease where cells in the breast grow out of control. Chemotherapy is a type of cancer treatment that uses drugs to destroy cancer cells. The study aims to understand if these treatments have specific effects on the heart and physical activity levels.
Participants will undergo various procedures to assess their heart health and ability to exercise. This may include tests like treadmill or stationary cycle exercises, where participants' heart rates and physical responses are monitored. The study will compare results between those receiving chemotherapy and those who are cancer-free.
- Who can participate: Women with Stage I-III breast cancer scheduled for chemotherapy can participate. Healthy women without cancer can also join for comparison. Participants must be able to walk two blocks and exercise on a treadmill or stationary cycle.
- Study details: Participants will be involved in exercises and health assessments to monitor heart and physical activity responses. The study includes a comparison between those receiving chemotherapy and healthy individuals. A placebo is not used in this study.
