Studies of colon and breast cancer patients link healthy habits to better outcomes amid slew of research on lifestyle and cancer
A healthy diet and exercise could reduce colon cancer patients’ chance of death and simply walking could improve survival rates for breast cancer survivors, studies presented at the world’s largest cancer conference have found.
A study of nearly 1,000 colon cancer patients found that those who exercised regularly, ate more fruits and vegetables and avoided refined grains and meats had a 42% lower chance of death after seven years.
Similarly, a study of more than 300 Australian breast cancer survivors who aimed to exercise for 180 minutes per week – most by simply walking – had far better rates of survival than those who were not part of an exercise program.
The studies were presented amidst a slew of research on the impact of a healthy lifestyle on cancer, presented at the American Society of Clinical Oncology (ASCO) in Chicago.
“Most of what we know about the importance of exercise post-cancer comes from studying women with breast cancer,” said Sandra Hayes, an epidemiologist studying cancer and exercise at Queensland University of Technology in Australia.
Studies conducted on the relationship between exercise and other types of cancer, she said, held up a general set of findings.
“Engaging in some activity [or] exercise is better than none, and doing more is generally better than less,” Hayes said.
Researchers acknowledged that studies on the effects of exercise and cancer recurrence remain epidemiological, and that causal links are yet to be established. Further, the mechanisms through which exercise may influence cancer survival remain “unclear”.
In one study, researchers at the University of California San Francisco and colleagues aimed to test whether American Cancer Society (ACS) nutrition and exercise guidelines for cancer survivors could impact survival among colon cancer patients.
In general, the guidelines recommend moderate exercise of 150 minutes per week, eating a diet rich in whole grains, fruits and vegetables, and keeping a healthy body weight. The ACS has detailed guidelines for nutritional and exercise standards for cancer survivors, addressing everything from exercise to eating recommendations forthose who have little appetite.
Researchers found that even colon cancer survivors who drank moderately while following other guidelines had a 42% lower chance of dying than those that did not.
