Breast cancer is the most common cancer among women worldwide.

While there are several risk factors for breast cancer, including age, genetics, and environmental factors, lifestyle changes can also significantly reduce the risk of developing breast cancer. In this article, we will explore how regular exercise and less sedentary behavior can help reduce the risk of breast cancer.

The Link Between Exercise and Breast Cancer

Research has shown that women who engage in regular physical activity have a lower risk of developing breast cancer as compared to those who are less active.

Exercise helps reduce the levels of estrogen and other hormones that are linked to an increased risk of breast cancer. Also, regular exercise can help reduce body fat, which is associated with an increased risk of breast cancer.

The Benefits of Exercise for Reducing Breast Cancer Risk

There are several benefits of exercise for reducing breast cancer risk. Some of these include:.

Reducing the levels of estrogen and other hormones that are linked to an increased risk of breast cancer
Reducing body fat, which is associated with an increased risk of breast cancer
Strengthening the immune system, which helps fight cancer cells
Reducing inflammation in the body, which can increase the risk of cancer
Reducing insulin resistance, which is linked to an increased risk of breast cancer
Promoting healthy cells and preventing the growth of cancer cells

How Much Exercise is Required to Reduce Breast Cancer Risk?

While any amount of physical activity is better than none, research suggests that women should aim for at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week.

This can include activities like brisk walking, cycling, swimming, or running.

Less Sedentary Behavior for Reducing Breast Cancer Risk

While regular exercise is important for reducing breast cancer risk, it is also important to reduce sedentary behavior. Sedentary behavior refers to time spent sitting or lying down, such as watching TV or working at a desk.

Studies have shown that prolonged sedentary behavior is associated with an increased risk of breast cancer, regardless of how much exercise a woman engages in.
