The leading causes of death for U.S. men are heart disease, cancer (colorectal, testicular, prostate, and lung), stroke, lung disease, accidents, and diabetes. The risk of developing these conditions can be lowered with a healthy lifestyle, healthy diet, regular exercise, and regular health care. Many conditions, such as high blood pressure and high cholesterol, are silent illnesses. They don't cause symptoms that may lead to a doctor's visit. Routine checkups and screenings are important for finding hidden problems and staying healthy.
