Mutations in predisposing genes for some of the hereditary forms of cancer exhibit autosomal dominant mode of
inheritance. Introduction of genetic tests for these mutations to the clinical practice initiated studies focused on the
psychosocial factors associated with genetic testing. Undergoing the genetic testing is a stressful experience for both
the healthy individuals in risk and the patients already affected with cancer. The psychosocial characteristics of the
tested individual influence not only the psychological functioning during the testing but also the acceptance of the
test, and generally his life style and health practices. Psychological support during the genetic testing process is
mostly provided by the genetic counsellor. The findings of psychosocial studies might be therefore helpful for the
focusing of the genetic consultation, and fulfilling the client needs and expectations towards testing. Factors of
motivation, psychological state, influence of family situation and support, and optionally the involvement of
a psychologist into the process of genetic testing are observed.
