Description:
A laboratory method that looks for genetic changes across all the DNA (including the entire set of genes) in a person or in a specific cell type or tissue. Genomic testing is done on samples such as blood or saliva to identify inherited genetic changes that may increase the risk of developing a specific disease or condition, such as cancer. Genomic testing on a tumor sample is done to detect all the genetic changes in the cancer cells. This may help doctors learn more about the cancer, including how quickly it is likely to grow and spread and how well it may respond to certain types of treatment.
