Precision Medicine

Precision Medicine is Improving Health Care

Precision medicine takes a team. Physicians, nurses, and any number of specialists such as pediatricians, gynecologists, or oncologists can benefit from the medical science of genetics.

Advances in technology and genomic research will improve health care now and into the future. Watch this video from Career OneStop to learn more.


Genetics is a field of biology that studies genes, heredity, and genetic variation. The genetic variation includes how changes in genes are involved in disease and aging.

Genetics professionals work as members of health care teams providing information and support to individuals or families who have genetic disorders or may be at risk for inherited conditions. Your health care provider might recommend a genetic test, a procedure to identify genetic variants in DNA. A sample of saliva or blood can be used to study your DNA. Watch the below video from The National Society of Genetic Counselors to learn more. 

Geneticists are physicians who specialize in diagnosing medical conditions that have a genetic basis.

Genetic Counselors help patients and families understand and make informed decisions about their genetic health. They can help explain the various tests, the return of information, and the options available to you. They also can help you talk to your family about genetic factors and help arrange for emotional or psychological support. Learn more about Genetic Counseling.


Pharmacogenomics is the study of how people respond to medicines based upon genomics. By maximizing drug benefits and minimizing drug toxicity, this field of precision medicine can help your physician and pharmacist select the right medication, and the right dose, based on your personal genetic make-up. Learn more about Pharmacogenomics.


A new tool, the genomic tumor assessment, may result in a more personalized approach to diagnosing cancer. It can compare the differences between your cancer cells and your normal cells. This tool can help identify how the tumor came to exist and can help your oncologist select a treatment that works best for stopping the tumor's growth based on your precise genetic make-up.
