EXERCISE REDUCES CANCER RISK

NEW EVIDENCE ON HOW WEIGHT, DIET AND EXERCISE CAN HELP REDUCE CANCER RISK.

Cutting your risk of cancer is no longer just about shunning tobacco. Be lean. Eat healthfully. Get active. Common-sense lifestyle strategies for lowering the risk of heart disease and diabetes are now being shown to help prevent many types of cancer.

 Of course, there are few absolutes in cancer prevention. Cancer is still a riddle, with many factors, including genetics, playing a role. But growing evidence suggests that there are steps that we can take to lower our chances of getting the disease, experts say.

 Otis Brawley, chief medical officer for the American Cancer Society, urges careful attention to the “three-legged stool” of excess weight, poor diet and inadequate physical activity, which together are linked to between a quarter to a third of cancer cases. If tobacco use continues its decline of the past 15 years or so, he said, that trio may supplant smoking as the leading preventable cause of cancer.

Indeed, a recent study found that women who followed the ACS Guidelines on Nutrition and Physical Activity for Cancer Prevention lowered their risk significantly. Those guidelines include maintaining a healthy weight, adopting a physically active lifestyle, consuming a healthful diet that emphasizes plant-based food, and limiting alcohol intake. Data on more than 65,000 post-menopausal women tracked for more than 12 years found that compared with those who were least compliant with the ACS guidelines, the women who followed them most closely had a 17 percent lower risk of any cancer, a 22 percent lower risk of breast cancer and a 52 percent lower risk of colorectal cancer, according to a study released in January.

 “This suggests that even later in life, if you are making healthy choices it seems to be protective in terms of cancer risk,” said lead author Cynthia Thomson, a professor in the college of public health at the University of Arizona. The women who best adhered to the guidelines were also 27 percent less likely to have died during the time frame of the study.

 This study builds on 2011 research that found a lower risk of death from cancer, cardiovascular disease and all causes for nonsmokers who followed the ACS guidelines, which include:

 1. Maintain a healthy weight throughout life.

 Being as lean as possible and maintaining a healthy weight are key components of cancer prevention. People should aim for body mass index (BMI) score of 18.5 to 24.9, according to the ACS. “The data are becoming more and more consistent that gaining excess weight as we age, and even children being very heavy, can increase risks for cancers later in life,” said Rachel Ballard-Barbash of the National Cancer Institute.

 According to the ACS, extra body weight is associated with greater risk of cancers of the breast, colon and rectum, endometrium, esophagus, kidney and pancreas. Added weight also probably raises the risk of such cancers as gallbladder, liver, non-Hodgkin lymphoma, multiple myeloma, cervix, ovary and prostate.

A study published in 2003 in the New England Journal of Medicine found increased body weight associated with increased death rates for all cancers. The same association applied to deaths from many specific cancers including esophagus, colon and rectum, liver, gallbladder, pancreas and kidney, as well as non-Hodgkin lymphoma and multiple myeloma. Poor BMI scores were associated with cancer deaths of the stomach and prostate for men and of the breast, uterus, cervix and ovaries in women. Large body size in childhood, adolescence and young adulthood predicted increased risk of non-Hodgkin lymphoma in a 2013 study in Cancer Prevention Research.

 2. Get active.

 Your level of physical activity may affect your risk of several kinds of cancers: breast, colon, endometrium and prostate, according to the ACS.

 A sedentary lifestyle, coupled with overeating, can create an energy imbalance that causes abnormalities in the body. If you are in the habit of taking in too many calories compared with what you burn, this imbalance can spur metabolic and hormonal changes and inflammation that may fuel many diseases, including cancer, heart disease and diabetes, Ballard-Barbash said. She said people who develop cancers such as colon, breast, lung and prostate often have other diseases as well, because some of the same mechanisms affect all these diseases. That is why controlling activity, weight and diet is so crucial to disease prevention and overall health.

 Research in this area is growing. For example, post-menopausal women who walked seven hours a week had a 14 percent lower risk of developing breast cancer compared with those who walked fewer than three hours a week, according to an October 2013 study.

 The ACS recommends at least 150 minutes of moderate-intensity aerobic activity such as brisk walking or 75 minutes of jogging weekly. A similar recommendation comes from the American Institute for Cancer Research, which calls for being physically active at least 30 minutes a day, with maximum health benefits coming from 60 minutes or more of moderate activity or 30 minutes or more of vigorous activity daily.

 3. Eat healthfully.

 Over the past 50 years there have been many studies on the health effects of individual nutrients and foods. One week researchers report on the benefits of coffee; the next, it’s the benefits of nuts or the negatives of sugary beverages. For preventing disease, the current trend is to think about the entire diet or dietary patterns, rather than the particulars of dozens of foods or nutrients, Ballard-Barbash said.“We don’t know of a diet that definitely will prevent cancer,” said Moshe Shike, a cancer prevention expert at Memorial Sloan Kettering Cancer Center in New York. But, he added, “we have very strong evidence that a healthy diet can reduce the risk of certain cancers and [that] unhealthy diet and obesity are associated with increased risk.”

 

The ACS recommends a diet rich in plants and whole-grain foods, especially one that controls calories consumed. The timing of your meals may jump-start your metabolism and help you balance your energy and burn calories efficiently, said Ballard-Barbash. She noted that studies seem to suggest that by simply eating your evening meal earlier and redistributing calories throughout the day, as opposed to eating later in the evening, may help reduce how many calories you eat and how well your body burns those calories, Ballard-Barbash said.

 Shike and others recommend a diet rich in fruits and vegetables, with little red meat and more fish, whole grains and nuts. Thomson suggests that half your dinner plate consist of plant-based foods.

 Cancer prevention experts also advise avoiding tobacco, limiting alcohol, knowing your family history, being careful about sun exposure and getting age-appropriate screening. They also suggest getting vaccinated against two major cancer-causing viruses: hepatitis B virus (HBV), linked to liver cancer, and human papillomavirus (HPV), which is linked to cervical and throat cancers.

In acknowledging that cancer is not completely preventable, many experts use driving metaphors to explain managing the risk. “We will wear seat belts. Most of the time we don’t need them,” said Edward Giovannucci, a professor of nutrition and epidemiology at the Harvard School of Public Health. “But most people think it’s worth putting on seat belts. It makes sense to follow these guidelines.”

“We don’t play a blaming game,” Shike said. “It’s not about that. It’s about starting from today moving forward. You can’t change the past. But you can do things to improve your chances and decrease your risk.”

No Big Deal!

 

Your child didn’t want to go to school today.

(S)he said (s)he “didn’t feel well.” So you let your child stay home.

No big deal.

It’s very cold outside and you don’t have a car available to drive your child to school. So you let your child stay home.

No big deal.

You usually drive your child to school but your car won’t start today. So you let your child stay home.

No big deal.

Your child frequently arrives a few minutes late for school because of the many things that have to be done as part of the busy morning routine.

No big deal.

Or is it?

 

What is your child learning from you about the importance of attending school?  What would your child learn from you about following through on commitments in the situations just described?

You want your child to be successful in school, in life. Regular attendance is vital to your child’s success in school in the same way that it will be vital to his or her success in a job.  Patterns are now being formed in school, in life. What kind of pattern is your child forming? What are you doing to contribute to that pattern?  You have the responsibility of ensuring the regular attendance of your child at school.

Why is regular attendance so important?

Because if your child frequently is absent(s)he misses valuable contact with classmates, class instruction and group discussion, even though (s)he may make up written work.  Of course, there are some valid reasons for keeping your child home from school.

• significant illness
• family emergency
• observance of
• a religious holiday
• death in the immediate family
• circumstances which cause you concern for the safety or health of your child

 

But what is ‘significant illness’?

School nurses have come up with some guidelines for you to use in deciding when your child is too ill to be in school.

Keep your child home:

1. If a rash is present that has not beenevaluated by a physician.

2. If your child’s oral temperature exceeds 100 F, or one to two degrees above the child’s normal temperature. A child with such a fever should remain home for 24 hours after the temperature returns to normal.

3. If the child vomits and continues to experience nausea and/or vomiting.

4. If your child complains of severe, persistent pain, the symptom should be referred to a physician for evaluation.

5. If your child shows signs of upper respiratory infection (cold symptoms) serious enough to interfere with the child’s ability to learn.

6. If there are signs of conjunctivitis “pinkeye” with matter coming from one or both eyes, itching, crusts on eyelids, the child should be evaluated by a physician.

7. If there are open sores that have not been evaluated by a physician.

8. If there are signs of infestation with lice(nits in the hair, itchy scalp) the child should be evaluated for treatment with a pediculicide.

If you are not sure about whether to send your child to school, call the school nurse for consultation.  But, generally speaking, don’t send the child to school for the nurse to make the decision unless the school asks you to. If you’re still in doubt, call or visit your child’s physician.  But what do you do when your child tells you (s)he “doesn’t feel good” or “doesn’t want to go to school” and you have serious doubts that (s)he is really sick?

Maybe you explain to him/her that there are times when each of us doesn’t feel so great, doesn’t feel quite up to par, but we go to work anyway.

Maybe you point out that sometimes you have to go out there into the world of school or a job or other responsibilities, even if you are not 100% comfortable. You help your child make the distinction between being uncomfortable and being really sick.

Ensuring your child’s regular school attendance is a major way for you to help your child learn how to fulfill one’s responsibility.

No Big Deal?

Yes it is.

 

Helping your child to succeed is a very big deal. Your school is willing to help If you are having a problem getting your child to attend regularly, call the school.

They have personnel who are able to work with you and help you.

Don’t cover up the real problem by calling your child in “sick” when (s)he really isn’t.

That only increases the problem.

The child who misses school today without a valid reason could become the dropout of the future.

And that could be a big deal. Especially if it’s your child.

Don’t let it happen.

Help is a phone call away.
