Obesity and Cancer Risk: Why a Healthy Weight Matters

Carrying excess body fat can increase your risk of developing several types of cancer, including breast cancer after menopause, colon, uterine, kidney, and pancreatic cancers. Excess body fat can contribute to chronic inflammation, higher insulin levels, and changes in hormones that may encourage cancer development. The good news is that taking steps toward a healthier weight can improve your overall health and may help lower your risk of certain cancers. Even modest weight loss can improve metabolic health and reduce inflammation. Maintaining a healthy weight through balanced nutrition, regular physical activity, and appropriate medical treatment is an important part of protecting your long-term health.
