Genomics and breast cancer screening.

Many women fear the risk of developing breast cancer, and some women have increased fear because of their family history. Thankfully, the study of genetics has brought forth tools to better identify women at risk. An understanding of genetics and cancer has led to genetic testing protocols which enable at-risk women to take preventative action through medication, surgery, and intensive screenings. These protocols not only have the potential to prevent cancer but also lead to early detection. Appropriate screening for women at risk for genetic breast cancer is essential for patient care. These screenings include specific risk assessment tests, genetic counseling, and genetic testing. To provide the best possible care for patients, providers must have a basic understanding of cancer, genetics, screening tests, genetic testing, and available prevention measures.
