Physical activity reduces the risk of developing up to 9 types of cancer

More and more studies are accumulating in favour of Practice of physical exercise as a way to be healthy and prevent various diseases. Now, an important new investigation that followed more than 1 million young men in Sweden during a average of 33 years, provided important conclusions on the exercise-cancer relationship.

The study, published yesterday in the British Journal of Sports Medicine, It found that men with high levels of cardiorespiratory fitness in early adulthood had a lower risk of developing up to 9 forms of cancer in the future in lungs, kidneys and gastrointestinal system, among other organs.

The research took as its starting point the Physical tests performed on more than one million young Swedes 18-year-old during tests to enter military service, which included pedaling on a stationary bike with increasing levels of resistance. The results of this analysis were used to classify participants into different levels of cardiorespiratory fitness.

The test consisted of riding a bicycle stationary, first with a low resistance level for five minutes, then with an increase in resistance of 25 watts per minute until the participants were too tired to continue.

The authors of the new study classified the participants into Low, moderate and high levels cardiorespiratory fitness, a measure of how well a person’s cardiovascular and respiratory systems deliver oxygen to muscles, based on the results of their bicycle tests.

They found that people with high levels of fitness had 19% lower risk of head and neck cancer and 20% lower risk of kidney cancer compared to the low fitness group.

Meanwhile Lung cancer risk was 42% lower for fittest participants, although that was mainly explained by people’s smoking habits. Despite its findings, the study has limitations, such as not including women and not assessing participants’ lifestyles after initial testing.

The doctor Aron Onerup, lead author of the study and member of the University of Gothenburg in Sweden, stressed that you don’t have to be an elite athlete to get these benefits. “Simply improving fitness can reduce the risk of several cancers,” said Onerup, who also noted a surprising finding: Those with high fitness had a nearly 40% lower risk of developing gastrointestinal cancers.

Consulted by Infobae, the doctor Diego Kaen (MP 1898), president of the Argentine Association of Oncology (AAOC), Remarked the Importance of the practice of physical exercise with respect to cancer and other diseases.

“Physical fitness, exercise, greatly influences health, not only in cancer, but also for example in cardiovascular disease. Now, one has to understand that if one manages not to smoke, not to drink alcohol, to consume a healthier diet based on fibers and vegetables, and to exercise at least 3 to 4 times a week 60 minutes of aerobic activity, can decrease up to 40%, the chance of having a cancer” said the expert.

There is no maneuver that decreases a person’s chance of having a cancer so much that the change of lifestyle habit. As for the exercise There are many studies that show two things, first that exercising physiologically decreases the inflammatory process of the body and the power to have cancer. It has also been studied that regular aerobic activity decreases the likelihood that a person who had cancer will suffer from it again. This It is fully studied in breast cancer and colon cancer for example,” said Kaen, who is director of the clinical research department at the Centro Oncológico Riojano.

As to why the exercise should be incorporated withor habit of life, the also professor of the National University of La Rioja indicated that exercise is part of the change of habits of life. “Exercise is healthy in terms of stress reduction, What does it imply? lower inflammatory state of the body. It means assimilating food better, reducing enzymes such as insulin, for example. I mean, there are a lot of medical factors that drive a healthy life. And let’s remember that healthy living is part of the prevention of many cardiovascular, bone, rheumatological and cancer diseases,” concluded the specialist.

Meanwhile, the doctor Ramiro Heredia Clinician of the Department of Internal Medicine of the Hospital de Clínicas José de San Martín Infobae that regular physical activity has beneficial effects on health. “It is tested on Protective effect of regular exercise against cardiovascular disease that is, risk of having a myocardial infarction, a stroke, a sudden death of cardiac causes. It also helps prevent or control different risk factors for diseases associated with cardiovascular disease such as high blood pressure, dyslipidemia, type 2 diabetes mellitus, obesity and overweight”

“Regarding cancer there is scientific evidence that tells us that People who get regular physical activity have a lower risk of several types of cancers And in case of getting sick they have a better prognosis. We know today that being in good physical condition and practicing physical activity on a regular basis reduces the incidence of different types of cancers. A study published a few years ago observed a reduction in lung cancer of 47%, colorectal cancer of 26% and cancer in general of 86%. That is why in the daily medical consultation and through different biomedical institutions and health authorities, practicing physical activity on a regular basis has to be within the recommendations, “said Heredia.

“Without going any further last year the American Heart Association published the list of the eight essentials of life in which physical activity is one of them, along with sleeping properly, controlling cholesterol, controlling glucose, controlling high blood pressure, having a normal body weight, having a balanced diet not smoking, among others, “concluded the specialist of the Hospital de Clínicas.

A recent study published in the journal JAMA Oncology, conducted by the Faculty of Health Sciences at the University of Sydney, Australia, has revealed that Just 5 minutes a day of vigorous physical activity can significantly reduce the risk of cancer. This activity refers to short, vigorous exercises, such as brisk walking, climbing stairs, or running to reach public transportation.

Researchers analyzed the physical activity of more than 22,000 adults over a 7-year period And they found that those who engaged in 3-6 minutes daily of intense physical activity had 17-18% lower cancer rates. In addition, those who averaged 4.5 minutes a day of this activity were up to 32% less likely to develop oncological diseases.

In a comprehensive scientific review conducted in 2016 and published in JAMA Internal Medicine, the researchers found that the likelihood of developing 13 common types of cancer, such as breast, stomach, bladder, colon and blood, was greatly reduced in men and women who exercised regularly.

One Latest study, carried out in 2022, concluded that approximately 46,356 annual cases of cancer in the United States, Accounting for about 3% of all cases, they could be prevented if everyone who doesn’t currently exercise started doing so.

However, it is important to note that most of this research focused on individuals who exercised for at least 30 minutes almost every day. This amount of time is the minimum recommended by the WHO, raising the question of whether shorter periods of physical activity could also have a significant impact on reducing cancer risk.
