Knowing the exact reason why a person develops cancer is nearly impossible to pinpoint. However, research indicates there are some risk factors that may increase the likelihood a person will get cancer. Some of the well-known risk factors include using alcohol, poor diet, radiation, current or previous use of tobacco, overexposure to sunlight, obesity and hormones. Family history of cancer may also lead to a higher risk of developing cancer.
If you believe you may be at risk for cancer, talk with your primary care doctor to identify your specific risk factors and to learn more about available screening options.
