Breast Cancer Studies Examine Impact of Drinking, Exercise
It wasn't too long ago that I remember hearing how beneficial red wine--in moderation!--was for my health. Its antioxidants were found to reduce risk of cardiovascular disease, and even inhibit types of tumor growth. Additional benefits were found in its ability to aid in the formation of nerve cells, a boost for neurological conditions. A smooth Pinot Noir, a poignant Shiraz, a cozy Cab, bring ‘em on.
A study mid-month, however, out of the American Association for Cancer Research Annual Meeting in San Diego, found that both excessive and moderate amounts of alcohol drinking--no matter the type--upped a woman's risk of the most common type of breast cancer. Even a drink a day could increase this risk; in this case, the women studied were postmenopausal. Researchers from Denmark and from a Harvard (Boston) study deduced similar findings among women in general. Results support the theory that alcohol affects estrogen metabolism.
On the flip side, researchers from the University of Texas Southwestern Medical Center in Dallas last week said that exercise may reduce breast cancer risk by lowering estrogen levels--assessing that estrogen may deactivate genes in breast tissue that suppress-cancer development.
Other brief tidbits making cancer study headlines last week: Two or three cups of coffee a day can cut the risk of breast cancer by a third or delay onset by 10 years. This one needs more data for substantiation, for sure. Oh yes, and let's not forget the role of mistletoe in aiding cancer treatment--a commonly prescribed extract in Europe for boosting immune systems and fighting the effects of chemo and radiation treatments. Researchers found that evidence supporting the use of mistletoe extracts was "weak" however, and recommended more data.
With various studies coming out each week about cancer linkages, cancer prevention tips, and information about various controllable and uncontrollable risk factors, it's important to keep sight of some main messages about healthy behaviors. Don't smoke. Don't consume alcohol; if you choose to, do so on a limited basis--with increased usage comes increased risks. Get screened for cancer early--colon, breast, cervical and skin. Protect your skin from the sun...when you're outside exercising! An active lifestyle--at least three to four hours a week of exercise--can cut your risk of several cancers in half. Exercise will also help keep your body mass index (BMI) at 25 or less; being overweight significantly ups your risk of developing several cancers. By eating at least five servings of fruits and vegetables a day, you can successfully manage weight, increase energy and nourish your body with vital nutrients. Reduce intake of fried, sugary, high-calorie foods as well as processed and red meats.
Patients must be educated on these and other healthy lifestyle choices--for their overall conditions and for a reduced risk of breast and other cancers. Many factors are out of our control, so let's take hold of what we can control.
