Eat Less and Exercise Vigorously to Prevent Cancer.

New guidelines from the American Cancer Society (ACS) emphasize exercise - real exercise, not just strolling from the car to the mall - as key to cancer prevention. The old recommendation was a cumulative total of 30 minutes a day five days a week of any type of everyday physical activity. Now the ACS is asking us to get serious and put in at least 30 minutes of moderate to vigorous activity in addition to everyday activities and suggests that more (45 to 60 minutes) is better. Moderate activities recommended are walking, dancing, cycling, skating, golfing and mowing the lawn. Vigorous activity means jogging or running, weight training, aerobics, swimming, soccer or racquetball. Losing weight by exercising more and eating less can prevent breast cancer in postmenopausal women. And an ACS spokesperson said it might also cut down on cancers of the colon, endometrium, esophagus and kidney. Other malignancies including cancers of the pancreas, gallbladder, thyroid, ovary, cervix, multiple myeloma, Hodgkin disease and aggressive prostate cancer may also be linked to excess weight. The new ACS recommendations were published in the September/October 2006 issue of CA: A Cancer Journal for Clinicians.
