Exercise reduces the risk of developing 13 kinds of cancer

ByDarrell A.

It is a well-known fact that regular exercise can prevent obesity and can maintain a healthy body. furtherThe possibility that exercise suppresses proliferation of cancer cellsThere is a way of thinking that exercise has a good effect on cancer, such as existence, but the favorable influence of exercise has presented 144 thousand people's research results showing that it extends to 13 kinds of different cancers It was.

Many studies indicate that people exercising regularly are more difficult to become a specific cancer than those who just sit. On the other hand, these studies focused on some famous cancers such as breast cancer, colon cancer, lung cancer, and how it affects other cancers in detail It was not in a state.

American National Cancer Institute, Harvard Medical School, and other research teams from researchers in the US and Europe, investigated the impact of exercise on 26 different cancer incidence rates for 1.44 million participants in the long-term Observational research, Journal of American Medical Association ·JAMA Internal MedicineIt was announced in. Observations of the relationship between various cancers and exercise for more than 10 years have found that exercise has reduced the risk of developing 13 types of cancer.

Early studies were conducted in such a way that participants were asked weight, multiple health indicators, diet and exercise habits and tracked transitions such as illness and death of participants for over 10 years. As a result of this observation it was possible to confirm the possibility that the carcinogenic rate is influenced by regular exercise, so in order to gather sufficient research data, 12 large-scale studies led by the National Cancer Institute lead to 1.44 million adults We gathered gender data. As a result of analyzing these data using elaborate statistical methods, those who are performing moderate or active exercise, and those who are walking or jogging fast walking, compared to those who just sit , It was found that the incidence of multiple cancers was significantly lower.

Thirteen kinds of cancers, including milk, lung, colon, liver, esophagus, kidney, stomach, endometrium, blood, bone marrow, head and neck, rectum, and bladder, were observed to reduce the onset risk by exercise. Even with a small amount of exercise, there was a tendency for those exercisers to decrease the risk of developing these cancers than those who do little exercise. In addition, comparing the top 10% group that was doing the most exercise with the lowest 10% group that was not the most active, it is confirmed that the carcinogenesis rate is as much as 20%.

On the other hand, comparison between these two groups also shows that the group that improves exercise has a higher risk of developing malignant melanoma (melanoma) and slow growing prostate cancer. Steven Moore of the National Cancer Institute, who led the research, speculates that people who exercise often tend to go out and that the risk of sunburning increases malignant melanoma. . In addition, people who exercise often tend to receive medical examinations many times, because it is easy to find prostate cancer that is hard to be found in painlessness.

Although it is possible to reduce the risk of developing 13 types of cancer more to do more exercise, the risk of developing several other cancers will increase. However, since many other health benefits such as elimination of obesity are obtained in the exercise, it seems that people who are relatively exercising can be said to be healthier. The The New York Times, which took up the study, said that it is necessary to keep in mind that this is not a direct proof of the decrease in cancer risk due to exercise because of observational research.
