Breast cancer is one of the most common types of cancer worldwide. In the United States, it is estimated that more than 276,000 women will be diagnosed with breast cancer in 2020.

While there is no sure way to prevent breast cancer, there are several lifestyle habits that can help reduce your risk. One of the most effective ways is to engage in regular physical activity.

The Benefits of Exercise for Breast Cancer Prevention

Physical activity has numerous benefits for overall health, including reducing the risk of heart disease, stroke, and diabetes. Several studies have suggested that exercise can also help reduce the risk of breast cancer.

Researchers have found that women who are physically active have a lower risk of developing breast cancer compared to those who are sedentary.

One study published in the Journal of the National Cancer Institute found that women who engaged in regular physical activity had a 12% lower risk of breast cancer compared to those who were inactive.

Another study published in the British Journal of Cancer found that physically active women had a 25% lower risk of breast cancer compared to those who were inactive.

How Exercise Helps Prevent Breast Cancer

While the exact mechanism by which exercise helps prevent breast cancer is not yet fully understood, several theories have been proposed.

One theory is that physical activity helps regulate hormone levels, such as estrogen, which can promote the growth of breast cancer cells. Another theory is that exercise helps boost the immune system, which can help fight cancer cells.

Studies have also found that physical activity can help reduce inflammation in the body, which has been linked to the development of several types of cancer.

In addition, exercise can help reduce body fat, which has been associated with an increased risk of breast cancer.

How Much Physical Activity is Needed?

While any amount of physical activity is better than none, the American Cancer Society recommends that adults engage in at least 150 minutes of moderate intensity or 75 minutes of vigorous intensity exercise per week.

This can be achieved through activities such as brisk walking, cycling, swimming, or running.

It is important to note that the benefits of exercise for breast cancer prevention may vary depending on factors such as age, weight, and family history of breast cancer.

Women who are at high risk of developing breast cancer may benefit from more frequent or intense physical activity. It is always best to consult with your healthcare provider before starting a new exercise routine, especially if you have any pre-existing medical conditions.

Other Ways to Reduce Your Risk of Breast Cancer

In addition to regular physical activity, there are several other lifestyle habits that can help reduce your risk of breast cancer. These include:.

Eating a healthy diet rich in fruits, vegetables, whole grains, and lean proteins
Maintaining a healthy weight
Limiting alcohol consumption
Not smoking
Getting regular mammograms
