Risk FactorsIncreasing age is a risk factor for developing cancer. More than 87% of all cancers are diagnosed in persons aged 50 years or older. Other risk factors for cancer include a person's gender and family medical history. Cancer may also be linked to environmental exposures and lifestyle choices such as use of tobacco and alcohol, diet, and sun exposure. In fact, tobacco use remains the world's most preventable cause of death. Despite decades of declines in cigarette smoking prevalence, almost one-third (32%) of cancer deaths in the U.S. and as much as 40% in men in some Southern states are still caused by smoking.^1^[[br]]
