Primary care
-
Cancer is the second leading cause of death in the United States. Cancer risk assessment can be divided into two major categories: assessment of familial or genetic risk and assessment of environmental factors that may be causally related to cancer. ⋯ Special attention should also be paid to potentially modifiable cancer risk factors in the course of advising primary care patients regarding a healthy lifestyle. Clinical guidelines, targeting both genetic and modifiable cancer risk factors, are available and can facilitate the application of these health care principles in the primary care setting.
