Which statement regarding exercise and cancer is false?

The statement about the intensity of exercise for cancer patients is considered false because the recommended intensity often varies based on individual patient circumstances, treatment status, and general health. It is widely accepted that exercise for cancer survivors should be personalized, with many guidelines suggesting moderate-intensity activities. However, the 40-60% range typically refers to heart rate reserve or estimated maximum heart rate, which may not be suitable or safe for all cancer patients. Some individuals might benefit from lower or higher intensities based on their specific condition, treatment side effects, and overall physical capabilities.

The other statements support the beneficial role of exercise in cancer recovery and management. Research has shown that exercise can improve performance and quality of life for breast cancer patients. Additionally, it has been shown that regular physical activity can lower the risk of cancer recurrence, particularly in colon cancer patients, likely due to its positive effects on metabolism and immune function. Lastly, when exercise programs are tailored and supervised appropriately, they tend to have minimal side effects, promoting better patient adherence and long-term health benefits.
