Helpful Ways to Be More Active· Use stairs rather than an elevator.· If you can, walk or bike to your destination.· Exercise at lunch with your workmates, family, or friends.· Take a 10-minute exercise break at work to stretch or take a quick walk.· Walk to visit co-workers instead of sending an email.· Go dancing with your spouse or friends.· Plan active vacations rather than only driving trips.· Wear a pedometer every day and watch your daily steps increase.· Join a sports team.· Use a stationary bicycle while watching TV.· Plan your exercise routine to gradually increase the days per week and minutes per session.Maintain a healthful weight throughout life.Balance caloric intake with physical activity.Lose weight if currently overweight or obese.Being overweight or obese is associated with an increased risk of developing several types of cancer: · Breast (among postmenopausal women)· Colon· Endometrium· Esophagus· Gallbladder·

Pancreas· KidneyIf you drink alcoholic beverages, limit consumption.People who drink alcohol should limit their intake to no more than 2 drinks per day for men and 1 drink a day for women. The recommended limit is lower for women because of their smaller body size and slower metabolism of alcohol. A drink is defined as 12 ounces of beer, 5 ounces of wine, or 1.5 ounces of 80 proof distilled spirits.Alcohol is an established cause of cancers of the: · Mouth· Pharynx (throat)· Larynx (voice box)· Esophagus· Liver· BreastAlcohol may also increase the risk of colon cancer.Diet and Physical Activity Factors That Affect Risks for the Most Common CancersAlthough the nutrition and activity guidelines are intended to reduce overall cancer risk, certain dietary and physical activity habits affect the risk for developing specific types of cancer. This section summarizes the relation of diet and physical activity factors to the common cancers in the United States.Bladder CancerThe major risk factors for bladder cancer are tobacco smoking and exposure to certain industrial chemicals.

However, drinking more fluids and eating more vegetables may lower the risk of bladder cancer.Brain CancerThere are no known nutritional risk factors for brain cancer.Breast CancerThe risk of breast cancer is increased by several factors that cannot be easily changed:· Having your first period before age 12· Not having children or having your first birth after age 30· Late age at menopause· Family history of breast cancerOther factors that increase risk, however, can be changed by: · Limiting the use of hormones (hormone replacement therapy)· Reducing alcohol consumption·

Breastfeeding· Avoiding obesity· Being physically activeSome studies also suggest that diets high in vegetables and fruits decrease the risk for breast cancer, although this evidence is much weaker than for other cancer sites. Alcohol increases risk to some extent, however, and exercising longer and harder may be linked to a reduced risk of breast cancer.The best advice to reduce the risk of breast cancer is to:· Engage in vigorous physical activity at least 4 hours a week· Avoid or limit your intake of alcohol to no more than one drink per day·

Reduce lifetime weight gain through the combination of limiting your calories and exercising regularlyColorectal CancerThe risk of colorectal cancer is higher for those with a family history of colorectal cancer. In addition to diet and physical activity, several other factors are linked to this cancer. Risk is increased by tobacco use and may be decreased by use of aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDS) and, possibly, by hormone replacement therapy. Currently, however, neither aspirin-like drugs nor postmenopausal hormones are recommended to prevent colorectal cancer because of their potential side effects.Some studies show a lower risk of colon cancer among those who are moderately active on a regular basis, and more vigorous activity may even further reduce the risk of colon cancer.

Being inactive is linked more to an increased risk of cancer of the colon than cancer of the rectum. Diets high in vegetables and fruit may lower the risk, and diets high in red meat may increase the risk of colon cancer. Some evidence shows that folic acid supplements may reduce the risk of colon cancer.The best advice to reduce the risk of colon cancer is to:· Increase your physical activity· Eat more vegetables and fruit· Limit intake of red meats· Avoid obesity· Avoid excess alcoholIn addition, it is very important to follow the ACS guidelines for regular colorectal screening because finding and removing polyps in the colon can prevent colorectal cancer.Endometrial CancerStudies of endometrial cancer (cancer of the lining of the uterus) show that obesity and use of hormonal replacement therapy after menopause increase risk.

The link to weight is thought to result from the increase in estrogen levels that occurs among postmenopausal women who are overweight.The best advice to reduce the risk of endometrial cancer is to maintain a healthful weight through diet and regular physical activity.Kidney CancerKidney cancer risk is increased among those who are overweight. The reason for this is unknown. The best nutritional advice to lower risk for kidney cancer is to avoid becoming overweight.Leukemias and LymphomasThere are no known nutritional risk factors for leukemias or lymphomas.Lung CancerMore than 85% of lung cancers result from tobacco smoking. Many studies have shown that the risk of lung cancer is lower among both smokers and nonsmokers who consume at least five servings of vegetables and fruits a day.

Although healthful eating may reduce the risk of lung cancer, the risks from tobacco smoking, chewing tobacco, and snuff remain substantial. Using high doses of beta-carotene and/or vitamin A has increased (not decreased) lung cancer risk among smokers (see beta-carotene under Common Questions About Diet and Cancer).The best advice to reduce the risk of lung cancer is to avoid tobacco use or exposure and to eat at least five servings of vegetables and fruits every day.Oral and Esophageal CancersTobacco (including cigarettes, chewing tobacco, and snuff) and alcohol, alone and especially when used together, increase the risk for cancers of the mouth and esophagus. Obesity increases the risk for cancer occurring in the lower esophagus and at the junction of the esophagus and stomach; this is likely due to the increased acid reflux, in which stomach acid flows up into the esophagus.

Eating recommended amounts of vegetables and fruit probably reduces the risk of oral and esophageal cancers.The best advice to reduce the risk of oral and esophageal cancers is to:· Avoid all forms of tobacco· Restrict alcohol consumption· Avoid obesity· Eat at least five servings of vegetables and fruits each dayOvarian CancerThere are no firmly established nutritional risk factors for ovarian cancer, although fruits and vegetables in the diet may lower risk.Pancreatic CancerTobacco smoking, adult-onset diabetes, and impaired glucose tolerance increase the risk for pancreatic cancer.

Some studies have also associated obesity and physical inactivity (both factors strongly linked to abnormal glucose metabolism) with increased pancreatic cancer risk. A diet including fruit and vegetable is associated with a reduced risk.The best advice to reduce the risk of pancreatic cancer is to:· Avoid tobacco use· Maintain a healthful weight· Remain physically active· Eat five or more servings of vegetables and fruits each dayProstate CancerProstate cancer is clearly related to male sex hormones, but just how nutritional factors might increase risk remains uncertain. Several studies have found that eating large amounts of red meats and dairy products is associated with increased risk of prostate cancer. In addition, a high-calcium intake, primarily through supplements, has been linked to an increased risk for more aggressive types of prostate cancer.

Other studies suggest that diets high in certain vegetables (including tomatoes, beans, and other legumes) may be associated with decreased risk. The evidence for these associations is limited, however. The possibility that specific nutrients in foods, notably vitamin E, selenium, and lycopene, may protect against prostate cancer is being investigated.For now, the best advice to reduce the risk of prostate cancer is to:· Limit intake of animal products, especially red meat and high-fat dairy products· Eat five or more servings of vegetables and fruits each dayStomach CancerThe rates of stomach cancer are decreasing as a result of the reduced prevalence of chronic stomach infections by the bacterium Helicobacter pylori.

Year-round consumption of fresh foods made possible by refrigeration and other improvements in food preservation methods also have likely helped to reduce the rates.At this time, the best advice to reduce the risk of stomach cancer is to eat at least five servings of vegetables and fruits daily.
