There are various risk factors that can increase an individual’s chances of developing cancer. Some of the major risk factors include tobacco use, unhealthy diet, physical inactivity, excessive alcohol consumption, exposure to certain chemicals and radiation, and genetic predisposition. According to the American Cancer Society [https://www.cancer.org/cancer/cancer-causes.html], lifestyle factors such as smoking, poor diet, and lack of exercise account for about one-third of all cancer cases in the United States. However, it’s important to note that some cancers can occur without any known risk factors.
