How Exercise May Help Reduce the Risk of Breast Cancer

Breast cancer is one of the most common cancers affecting women worldwide. While maintaining a healthy diet is often recommended as part of a healthy lifestyle, research also suggests that regular physical activity may help reduce the risk of breast cancer.

A large study involving more than 131,000 women found an association between higher levels of physical activity and a lower risk of invasive breast cancer. Women with more sedentary lifestyles appeared to have a higher risk, while those who were more physically active had a significantly lower risk.

Can Exercise Lower Breast Cancer Risk?

Regular exercise may support overall health in several ways that could contribute to a lower risk of breast cancer. Physical activity can help maintain a healthy weight and support healthy blood pressure, cholesterol, and blood sugar levels.

Some research suggests that even exercising a few times per week may be beneficial. Aiming for approximately 150 minutes of moderate-intensity physical activity each week, such as brisk walking, cycling, swimming, or dancing, is a practical goal for many adults.

You do not need to start with intense workouts. If you are currently inactive, begin gradually and choose activities that you enjoy and can maintain consistently.

Why Is Physical Activity Important for Breast Health?

Exercise may influence several factors associated with breast cancer risk, including body weight and hormone levels. Maintaining a healthy weight after menopause is particularly important because excess body fat can affect estrogen levels.

Physical activity also has broader health benefits, including improved cardiovascular health, stronger muscles and bones, better mood, and improved overall fitness.

However, exercise is only one part of breast cancer risk reduction. Age, genetics, family history, hormonal factors, and other health conditions can also influence an individual’s risk.

How Can You Recognize Possible Symptoms of Breast Cancer?

Knowing what is normal for your breasts can help you notice changes that may need medical attention.

Possible signs and symptoms can include:

– A new lump or thickened area in the breast or underarm
– A change in breast size or shape
– Changes in the appearance of the skin
– Nipple changes or unusual nipple discharge
– Persistent breast or nipple pain
– Changes around the collarbone or armpit

Not every breast change means cancer. Breast tissue can naturally change during the menstrual cycle, pregnancy, breastfeeding, and menopause.

Nevertheless, a new or unusual change that does not go away should be discussed with a healthcare professional.

Breast Cancer Screening Matters

Regular breast cancer screening can help detect breast cancer earlier, sometimes before symptoms appear. The appropriate screening schedule depends on factors such as age, personal risk, and family history.

If you notice a new breast lump, persistent change, unusual discharge, skin changes, or another concerning symptom, speak with your doctor rather than waiting for it to disappear.

The Bottom Line

Regular physical activity is an important part of a healthy lifestyle and may help lower the risk of breast cancer. Aim to move regularly, maintain a healthy weight, eat a balanced diet, and follow breast cancer screening recommendations appropriate for you.

Remember: Exercise can help reduce risk, but it cannot completely prevent breast cancer. Regular medical care and appropriate screening remain important.
