Exercise reduces cancer risk by at least 20%

For a healthy lifeNewly published scientific studies show that while exercise is beneficial for health, it significantly reduces the risk of developing diseases such as cancer, heart disease and diabetes. According to a new study published in the international medical journal JAMA, exercise significantly reduces the risk of developing many types of cancer. Cleveland Clinic’s Department of Oncology, Dr. Dale Sheppard makes the following analysis of the research: “This study; It shows that 13 different types of cancer are affected by people being more active.”

13 cancer types were found to be associated with exercise! Exercise;

  • Reduces risk of esophageal cancer by 42% — strongest effect
  • Reduces liver cancer risk by 27%
  • Reduces lung cancer risk by 26%
  • It reduces the risk of one type of blood cancer by 20%
  • It reduces the risk of breast cancer by 10%

More activity, less risk

The researchers analyzed data from 12 different studies involving nearly 1.5 million people in total, and wanted to see what effect recreational physical activity or exercise had on 26 different types of cancer. According to the data obtained; 13 of 26 cancer types (including colon, head, neck and breast cancers) show that increased leisure time physical activity is associated with a lower risk of cancer.

According to Dr. Shepard, there is a 20% or more reduction in cancer risk due to increased activity levels in seven types of cancer, including kidney, liver and lung.

Keys to preventing cancer

Scientists do not know exactly why exercise affects cancer risk. However, it is certain that exercise is one of the keys to helping prevent disease, according to Doctor Shepard. Some of the keys to preventing cancer are:

Eat well, get plenty of sleep, watch your weight and exercise. According to Doctor Shepard; “These are the things that prevent cancer. These help them get through their treatment more easily when someone gets cancer. So, exercise is the biggest part of it.”

It is well known that exercise is beneficial for your health and can reduce your risk of problems such as heart disease and diabetes. Researchers at the US National Cancer Institute wanted to find out if physical activity can reduce cancer risk as well as improve heart health. They also aimed to understand how the relationship was related to body size or whether the person smoked.

Results: In 13 of 26 cancer types, increased leisure time physical activity was associated with a lower risk of cancer, and exercise reduced the risk of developing any cancer by 7%.

The risk of disease is reduced

The conclusions reached by the researchers for active participants, from moderate to strong, are as follows;

  • 42% reduction in esophageal cancer risk — strongest effect
  • 27% reduction in liver cancer risk
  • 26% reduction in lung cancer risk
  • 20% reduction in risk of one type of blood cancer
  • 10% reduction in breast cancer risk

However, there is an increase in the risks of early stage prostate and skin cancers due to increased physical activity.


Researchers cite the sun as a possible cause of the increased risk of skin cancer because physical activity is mostly done outdoors. In addition, it has been observed that the physical activity-black tumor relationship is stronger in geographies where ultraviolet light is more intense. They think that physically active men are more likely to undergo prostate cancer screening. For this reason, these people are more likely to be diagnosed with this slowly developing, asymptomatic disease.

Free time activities

As part of this project, the researchers analyzed 1.4 million participants from 12 American and European study groups whose physical activity had been reported between 1987 and 2004. The team also looked at the incidence of 26 types of cancer in these people over an average of 11 years following.

Studies have focused on so-called leisure activities. Accordingly, leisure time activity is defined as physical activities that a person does to stay fit and healthy. Examples of such activities are walking, running or swimming. Participants reported how much time they spent each week on these activities. For example, per week A 150-minute walk is considered a moderate effort.

Even when researchers took body mass index into account, 10 of the relationships between cancer risk and activity level remained valid. The association between physical activity and lower risk for lung cancers becomes even stronger when researchers take into account whether participants smoke.
