Diet, Exercise, & Weight Control Improve Odds after Cancer Diagnosis
New guidelines from the American Cancer Society say for many cancers, maintaining a healthy weight, getting adequate physical activity, and eating a healthy diet can reduce the chance of recurrence and increase the likelihood of disease-free survival after a diagnosis.
Increasing evidence shows that excess weight, lack of exercise, and poor nutrition increase the risk of cancer recurrence and reduce the likelihood of disease-free and overall survival for many cancer survivors. “The data suggests that cancer survivors, just like everyone else, benefit from these important steps,” says Colleen Doyle, MS, RD, American Cancer Society director of nutrition and physical activity and coauthor of the guidelines. “While we’ve published previous reports outlining the evidence on the impact of nutrition and physical activity on cancer recurrence and survival, this is the first time the evidence has been strong enough to release formal guidelines for survivorship, as we’ve done for cancer prevention. Living a physically active lifestyle and eating a healthy diet should absolutely be top of mind for anyone who’s been diagnosed with cancer.”
Physical activity after cancer diagnosis is associated with a reduced risk of cancer recurrence and improved overall mortality.
While conducting research for the guidelines, experts in nutrition, physical activity, and cancer survivorship came up with the following:
- Avoiding weight gain throughout treatment may be important, not only for survivors who are overweight, but also for those of normal weight.
- Intentional weight loss after recovering from cancer treatment among overweight and obese people may be associated with health-related benefits.
- Evidence strongly suggests that exercise is not only safe and feasible during cancer treatment, but that it can also improve physical functioning, fatigue, multiple aspects of quality of life, and may even increase the rate of completion of chemotherapy.
- Physical activity after cancer diagnosis is associated with a reduced risk of cancer recurrence and improved overall mortality among multiple cancer survivor groups.
- Results from observational studies suggest that diet and food choices may affect cancer progression, risk of recurrence, and overall survival in people who have been treated for cancer.
- A dietary pattern high in fruits, vegetables, whole grains, poultry, and fish was found to be associated with reduced mortality compared with a dietary pattern characterized by a high intake of refined grains, processed and red meats, desserts, high-fat dairy products, and french fries in women after breast cancer diagnosis and treatment.
