Does the possibility of cancer haunt you or your family members? It doesn�t have to. New research shows that many common risk factors can be prevented. In fact, experts say that almost half of adult cancers can be avoided with healthy lifestyle changes. Learn what you can do...
Mamas, don�t let your babies grow up to be cancer patients. Teach your children early how they can lessen several major cancer risks.
�About 50% of deaths from adult cancers in this country could be prevented if people made lifestyle changes,� says Colleen Doyle, director of nutrition and physical activity at the American Cancer Society. �If we start early and prevent kids from smoking and encourage a healthy diet and physically active lifestyle, that figure could go even higher.�
Here are 5 things you can avoid to reduce the risk of cancer for you and your kids.
Cancer risk #1: Tobacco
Think today�s youths have gotten the message about the dangers of tobacco as a risk of cancer? Think again.
Nearly 20% of high school students said they were smokers, and nearly half reported they had tried smoking, according to the 2009 Youth Risk Behavior Survey, a national school-based poll conducted by the Centers for Disease Control and Prevention (CDC) and state governments
Even trying smoking can be dangerous, because addiction develops quickly in adolescents. A 2007 University of Massachusetts study found that 10% of 217 sixth-graders who smoked became dependent on nicotine within two days of taking their first puff. Half became dependent by the time they had smoked seven cigarettes per month.
What�s more, according to the American Cancer Society, the likelihood of developing lung and other cancers increases with smoking duration, so those who start smoking at younger ages and continue to light up are at the highest risk for death.
If your kids don�t smoke cigarettes, don�t breathe a sigh of relief just yet. Kids who don�t pick up cigarettes may be turning to other forms of tobacco, the cancer society cautions. An estimated 10%-20% of college students and 10%-17% of adolescents use tobacco in water pipes or hookahs.
What to do right now: Check out online tobacco prevention tools from credible, kid-friendly sites like KidsHealth, run by the nonprofit Nemours Center for Children�s Health Media. For help in getting a teen to quit smoking, the American Cancer Society recommends checking out online resources from Youth Tobacco Cessation Collaborative or the CDC.
And if you smoke, stop.
�Parents shouldn�t model the behavior they want their child to avoid,� says Eric Werner, M.D., chair of the American Academy of Pediatrics section on hematology/oncology.
Cancer risk #2: Tanning
It�s easy enough to slather young kids in sunscreen, dress them in sun-protective clothing and tell them to play in the shade. But persuading girls and young women to protect themselves from harmful UV (ultraviolet) rays � another risk of cancer � is a different matter.
Melanoma is increasing faster in females 15-29 years old than in males of the same age group, according to the American Academy of Dermatology. A 2008 study by the National Cancer Institute (NCI) found that rates of the disease have risen 50% among young women in the U.S. since 1980. In 2004, 13.9 per 100,000 young women were diagnosed with skin cancer, versus 7.7 per 100,000 young men.
Yet plenty of teen girls and young women remain tanning devotees, according to a 2011 survey by the Dermatology Academy. The majority, 81%, said they tanned outdoors frequently or occasionally, and 32% of the 3,800 respondents said they used tanning beds within the past year.
What to do right now: To talk some sense into a daughter hell-bent on looking like Kim Kardashian, appeal to her vanity. Telling young women about the toll that tanning takes on their appearance is surprisingly effective, according to a 2010 Northwestern University study of 430 college-age women who frequently visited tanning salons.
After the women were given booklets that detailed how ultraviolet rays destroy collagen in the skin and encourage wrinkles, their indoor tanning visits dropped 35% during the next six months. Some stopped tanning altogether.
Cancer risk #3: Obesity
Obesity and physical inactivity are second to tobacco use as cancer risk factors, according to the World Health Organization (WHO). Being overweight or obese is associated with an increased risk for 12 different cancers in women and 13 in men, Doyle adds, including cancers of the endometrium, colon, kidney and breast in postmenopausal women.
�We�ve seen cancer rates decline since the early �90s, but if we don�t get childhood obesity under control, that decline may not continue,� Doyle says.
Start thinking about your kids� weight now � not later. Obesity in adolescence is associated with increased risk of severe obesity in adulthood, according to a 2010 University of North Carolina study of nearly 9,000 people enrolled in the National Longitudinal Study of Adolescent Health. About 40% of the obese adolescents became severely obese by age 30, leading researchers to conclude that intervention might be most effective during childhood, before the worst weight gain occurs.
What to do right now: Create an action plan to get your kids moving. The American Cancer Society recommends that kids and teens get at least 30 minutes � but shoot for 45-60 � of moderate to vigorous physical activity five or more days of the week.
Need help inspiring your kids? Take some advice from the first lady. Michelle Obama�s Let�s Move initiative is dedicated to solving childhood obesity and offers simple steps to get kids exercising and eating right.
Cancer risk #4: Cell phone use
Concerned about your children�s cell phone habits?
In May, the WHO added cell phones, which emit low levels of radiation, to its list of possible carcinogens. But scientists don�t know yet how cell phone usage affects developing brains of children because only adults were studied.
There�s no need to panic over cell phones and cancer just yet, says Otis Webb Brawley, M.D., chief medical officer and executive vice president of the American Cancer Society.
For one, the WHO�s decision was based on a review of past epidemiological studies that showed correlation, but not causation.
In simple English, it identified factors associated with cancer, but didn�t prove that those factors caused cancer.
Some studies have found an association between heavy cellphone use and glioma and meningioma, two common types of brain tumors, but many other studies have not.
According to the American Cancer Society, of the 24 studies that looked at the possible connection between cell phones and brain tumors, most didn't find that people with tumors report greater cell phone use than people without tumors.
Last year, Interphone, the largest (more than 5,000 people in 13 countries) and longest (a decade) multinational study on the issue, coordinated by WHO�s International Agency for Research on Cancer, found no overall increase in risk of glioma or meningioma for cell phone users.
Moreover, Interphone researchers found no evidence among most users that risk increased as the number of calls, call time, or years of use increased.
The study, published in the International Journal of Epidemiology, did report that the small proportion of people who spent what was considered years ago to be a large amount of time � more than 1,640 hours or at least 30 minutes a day � on cell phones had a 40% increased risk of glioma.
But certain flaws in the study prompted the study�s researchers to rule the finding inconclusive.
Currently, the Food and Drug Administration says, �The weight of scientific evidence has not linked cell phones with any health problems.�
