Genetic testing involves examining your DNA, the chemical database that carries instructions for your body's functions. Screening, referred to as germline genetic testing, is easy and can be done with a simple saliva test or blood test. Genetic tests are when small samples of blood or body tissues are analyzed. During testing, the genes are separated from the rest of the DNA, and then they are scanned for abnormalities. A geneticist or genetic counselor can help families think about the benefits and limitations of a particular genetic test. Before testing is done, a person will usually have a risk assessment, in which they meet with a genetic counselor or other health care provider to review factors such as which of their relatives had cancer, what cancers they had, and at what ages they were diagnosed.
