Below is some advice on how to prevent cancer:

8 Ways to Avoid Cancer in Your Life

1. Eat Blueberries

Aside from being a healthy and delicious snack, blueberries contain pterostilbene, which has important colon（结肠） cancer-fighting prosperities. But wait, it gets better. Blueberries also offer a large dose of vitamins C (14 milligrams per cup). So at breakfast, try to take in a cup and a half of blueberries in your cereal or yogurt, or mixed with other berries.

2. Drink Pomegranate（石榴）Juice

The deep red juice of the pomegranate contains polyphenols, isoflavones and ellagic acid, which together create a powerful anticancer mixture. Most recently, researchers from the University of Wisconsin at Madison has discovered that 16 ounces of pomegranate juice per day also may inhibit the growth of lung cancer.

3. Relax

Feeling stressed or worried? Find ways to relax and you may reduce your chances of developing cancer. Purdue University researchers tracked 1,600 men over 12 years and found that half of those with high levels of worry died during the study period. Only 20 percent of the optimists died before the study were completed, while 34 percent of the extremely anxious men died of some type of cancer. Instead of stressing about the past or future, focus on the present and relax!

4. Take Selenium（硒）

Selenium is well known for its cancer-fighting properties. In a study of almost 1,000 men, researchers from the Journal of the National Cancer Institute found that when men with the lowest initial levels of selenium in their bodies received a daily supplement over a 4 year period, they cut their prostate（前列腺） cancer risk by a remarkable 92 percent. However, it is possible to get too much of a good thing, so monitor your intake of selenium-containing supplements, Brazil nuts, tuna, meats and grains carefully.

5. Eat Sushi（寿司）

Seaweed may not be your idea of a great snack, but it is high in fiber, calcium and iron, and dry, roasted seaweed sheets used in sushi provide the additional benefits of vitamins A and C. Sushi rolls are also high in protein— a typical spicy tuna roll has only 290 calories but packs 24 grams of protein. So don’t skimp（节省）on the Sushi!

6. Enjoy the Outdoors

Vitamin D causes early death of cancer cells. A study published in the American Journey of Clinical Nutrition reported that women who supplemented their diets with 1,000 international. Units of vitamin D every day had a 60 percent to 77 percent lower incidence of cancer ever a four-year period that did women taking a placebo(无效对照剂). Experts recommend supplementing your fun in the sun with 1,100 to 2,000IU of vitamin D each day.

7. Breathe Clean Air

There’s no question that secondhand smoke kills. A recent American Journal of Public Health study showed that nonsmokers working in smoky places had three times the amount of carcinogen（致癌物质） in their urine（尿） than nonsmokers working in smoke-free locations. What’s worse, their levels of the carcinogen rose 6 percent for every hour worked. Nine states have banned smoking in all workplaces, bars and restaurants. The message is clear: Do whatever you can to avoid the cloud of smoke.

8. Break a Sweat

Even a small amount of exercise can offer major cancer-fighting benefits. In a study of 29,110 men published in the International Journal of Cancer, men who exercised just once a week had a percent lower risk of metastasis(转移性) prostate cancer than men who didn’t work out at all. The better the frequency, duration and intensity of the exercise, the bigger the reduction in risk, according to the study.

1.To prevent yourself from catching colon cancer, you should eat ____ as often as possible.

2.A person is very likely to catch some type of cancer if ______.

3._____ will remarkably reduce the risk of men’s prostate cancer.

4.If you want to keep cancer away, it is particularly important to ______.

Do you constantly use the computer, whether for learning or entertainment? Computers give off radiation that is bad for your health, but here are some ways to protect yourself from computer radiation.

_1._ Green tea can be absorbed by the body easily into a form of vitamin A, which helps reduce radiation. _2._

It is advisable to attach a radiation filter plate （辐射过滤板） in front of your computer’s screen. Make sure to avoid putting any metal substances near your computer as these may have reflected some of the electromagnetic waves that are harmful to your health. _3._The brighter the screen the higher the radiation there will be and vice versa.

You can also put some radiation-absorbing plants such as several cacti near your computer to prevent radiation.

Make sure you do a skincare protection before sitting in front of the computer. _4._Wash your face soon after using the computer in order to reduce 70% of the radiation.

_5._ Old computer in general, has one to two times more radiations released than the new one within the same distance.

E. The simplest way is by drinking 2 & 3 cups of green tea every day.

F. If possible, purchase a new computer instead of using an old model computer.

G. It also helps keep our eyes see things clearly in the dark by improving the visual ability.

When it comes to the prevention of heart disease, women need to pay attention to their own special risks. And so do men. Surprisingly, even children and teens need to be aware- or at least the parents who want to keep them safe do. Thankfully, scientists have also made great leaps in figuring out the specific prevention strategies that work best for all. So now, knowledge is your best protection.
What Men Need to Know
According to the American Heart Association (AHA), at least half of the people who die suddenly from heart disease each year had no clue they were sick. Some think that half of all heart attacks strike out of the blue. Not true, insists Jennifer Mieres, a spokeswoman for the AHA. A 2004 study found that at least 90 percent of first heart attacks are caused by well-known problems like high cholesterol(胆固醇) or diabetes. “If you look closely,” says she, “you’ll almost always find a risk factor that was undiscovered, ignored, or not adequately treated.”
Lifestyle changes like adopting a healthy diet, getting out for regular exercise, avoiding tobacco, losing weight are the first line of defense.
What Women Need to Know
There are some special considerations for the women who are  healthy and want to make sure they stay that way. First, they shouldn’t smoke-no one should, but the habit is even harder on women’s heart than it is on men’s.
Women who find that they are at risk should talk to their doctor about taking a statin(他汀,药物名). Indeed, statins reduce the risk of heart disease, but there has been not enough evidence that they help high-risk women and it can’t guarantee the long-term safety. So it’s worth noting that a healthy diet and exercise also reduce cholesterol.
What Parents Need to Know
Last year, a study showed that overweight children and teens have arteries(动脉)that look like those of an average 45-year-old. New guidelines say these children should get a cholesterol test by age ten -- and even urge doctors to consider statins for those most at risk if nothing else works. The recommendations caused oppositions. Lifestyle changes such as diet and exercise are the best strategy, says Dr. Greer, a professor at the University of Wisconsin School of Medicine. Statins should be considered only for kids in danger.
