Number of new cancer cases
Cancer can be caused by internal factors like genetics and mutations, as well as external factors such as smoking and radiation. It occurs in the presence of uncontrolled growth and spread of abnormal cells. However, many cancer cases could be prevented, for example, by omitting cigarette usage and heavy alcohol consumption. Risk of developing cancer tends to increase with age and is the most common in middle-aged adults or those that are older. Nevertheless, cancer can develop in individuals of any age. Cancer can be treated through surgery, radiation, and chemotherapy, among other methods.
