It is said that exercise can prevent cancer. Why do some people who insist on exercise also get cancer?

In fact, there are many benefits of exercise. As the saying goes, life lies in exercise.

Exercise can not only reduce the chance of obesity and improve the benefits of cardiopulmonary function, but also prevent cancer.

Therefore, many doctors are recommending that you incorporate exercise into your life plan and be a person who insists on exercising.

What Is Cancer?

But some people are skeptical of this claim. It is said that exercise can prevent cancer, but why do so many athletes or people who insist on loving sports end up suffering from cancer unfortunately?

And some people who are lazy at home every day and are less active have not developed cancer?

You should really talk about this issue.

  1. Exercise can prevent cancer?
    Cancer has always been a topic that people talk about. How to prevent cancer seems to be difficult, but it is not without any rules.

Similar arguments have been put forward in many literatures, and most cancer problems will be solved with good exercise.

A similar study was published by the National Cancer Institute in the United States. In this study, the researchers followed up for 18 years, surveyed the exercise volume of 1.44 million people, and then compared the people who exercised the most and those who exercised less. What conclusions did they reach?

In fact, people who exercised more were also associated with a lower risk of cancer, such as a 42% lower risk of esophageal adenocarcinoma.

The corresponding risk of liver cancer is reduced by 27%, and the risk of lung cancer is also reduced by 26%.

Women, in particular, have a 10% lower risk of breast cancer if they exercise for a long time.

So in the eyes of many researchers, exercise may be a good means of preventing cancer, which is much better than some nutritional supplements.

In another study on the relationship between lifestyle and cancer prevention, after counting the relevant data of 51 million people, it found 10 best ways to prevent cancer.

Among them, the two most effective means are related to sports.

Don’t think that exercise has nothing to do with cancer. In fact, if you increase exercise, you are prolonging your life.

Why this conclusion?

In fact, this problem can be explained from three aspects:

  • Exercise can reduce weight.
    Many people know that the weight of the body will gradually decrease after exercise. Many obese people can improve their physical condition through exercise.

It is because of exercise that you are getting thinner and thinner, so the risk of cancer associated with obesity is also reduced.

In addition, because the body is stronger, both the inflammatory response and the immune function will be greatly improved, and the onset of cancer will not be so easy.

  • The immune system is strengthened.
    When a person is exercising, the body’s metabolism will be stronger, and many harmful substances in the body will be excreted with sweat, and these harmful substances are potential carcinogenic factors.

At the same time, due to the relationship of exercise, a series of changes in the body will also occur. Not only can it improve the mental state, but also help to increase the body’s immunity. Even if some cancer-prone cells appear, they will be discovered and removed in time.

  • Adjust the intestinal flora.
    Anyone who likes to exercise knows that their digestive system will also be greatly improved after exercise. Not only the appetite to eat is better, but also the bowel movement is more comfortable. And probiotics in your gut will also be healthier, helping to improve your immune system.

Many diseases related to the gastrointestinal tract will be reduced, and the possibility of gastrointestinal tumors will also be reduced.

  1. Some people who insist on exercising also suffer from cancer?
    But the top question is still unexplained. Why do some people who don’t like sports do not have cancer, but some people who love sports have cancer?

Remember, this is a question of probability.

Overview of the Basics of Probability

Although many data show that people who love sports are more likely to develop cancer, the occurrence of cancer is not caused by a single factor, but a combination of factors, such as living environment, eating habits, and family history of genetic diseases.

Do not think that as long as exercise can prevent all cancers, such an absolute thing is impossible in the eyes of doctors.

In the eyes of the tumor, there is nothing absolute.

Summarize
Having said so much, in fact, the most central idea is to suggest that you increase exercise. If you are at home every day and never want to go out, then your risk of cancer will definitely increase.

So is there a simple and effective way to fight cancer? In fact, it is very simple, that is, exercise. Going out for a walk is fine, exercising at least 30 minutes a day, 5-7 times a week is a good amount of exercise.

British Journal of Cancer

If you feel that your physical condition allows, you can appropriately increase your activity, as long as you can tolerate it, it is not a problem.

Of course, if you feel that your physical condition is not ideal and you will gasp after a little exercise, even a simple walk is a good choice for exercise.

Just going out for a walk is better than sitting at home.
