As already discussed, ethnic background can play a role. Although the idea of terminating a wanted pregnancy may seem unthinkable in many cases, sometimes couples do change their minds and opt to end a pregnancy after they learn about the medical and developmental consequences of the genetic abnormality involved. Therefore, it should not be taken for granted that a person will follow through with a decision that is made before he or she has knowledge of life-altering facts. Genetic counseling provides nondirective communication of medical information and options, as well as psychosocial support, for the individual or couple making these difficult decisions. Also, knowing that a genetic disorder is present allows for planning and for delivery at a center that is equipped to deal with potential perinatal complications.
Cancer is so common in family histories.
Most cancers are multifactorial, meaning they are due to both hereditary and environmental factors. My patient is concerned that she may lose her insurance if she is found to have a genetic disease. Concerns focus on both symptomatic and presymptomatic disorders. For example, Huntington's disease testing and inherited cancer predisposition are two clinical scenarios about which patients often fear insurance and job discrimination if a genetic alteration is detected. With this procedure, patients are identified only by a code number or pseudonym.
