Living with hereditary non-polyposis colorectal cancer; experiences from and impact of genetic testing.

Hereditary non-polyposis colorectal cancer (HNPCC) is one of our most common cancer syndromes and an increasing number of individuals live in families with verified hereditary cancer. We conducted an interview study to explore experiences from and perceived impact on life after genetic testing for HNPCC. Three major themes emerged: reactions and emotions, family relations and implications for life. Among the reactions described were suspecting heredity, feelings of guilt, the importance of experiential knowledge, and coping strategies. The impact on family relations was related to perceived responsibility for conveying information, encountering different reactions among family members, and difficulties in communication and relations. The implications described included uncertainty, adaptation, new choices and changes in life, family planning issues, and experiences of surveillance programs. We suggest that the themes and sub-themes identified should be taken into account during genetic counselling in order to facilitate the spread of information and to prepare family members for the impact on life that knowledge about hereditary cancer may have.
