Why is it critical to monitor vital signs before and during exercise for cancer survivors?

Monitoring vital signs before and during exercise for cancer survivors is crucial primarily to ensure safety and to identify any potential problems early. Cancer treatments can affect the cardiovascular system, respiratory system, and overall physical condition of survivors, making it particularly important to keep track of vital signs such as heart rate, blood pressure, and oxygen saturation.

By actively monitoring these signs, fitness professionals can quickly assess how a survivor is responding to exercise, ensuring that they are working within safe limits. This proactive approach allows for timely intervention if any abnormalities arise, such as excessive fatigue, dizziness, or abnormal heart rhythms. Hence, the primary focus is on safety and health management rather than other factors such as body composition, calorie expenditure, or exercise intensity adjustments.
