Genetics of Breast and Ovarian Cancer (PDQ®): Genetics - Health Professional Information [NCI] - Psychosocial Issues in Inherited Breast Cancer Syndromes


Apprehension about the impact of the test result was a more important factor in the reason to decline than concrete burdens such as time to travel to a genetics clinic and time away from work, family, and social obligations.[31] In 15% (n = 31) of individuals from 13 hereditary breast and ovarian cancer families who underwent genetic education and counseling and declined testing for a documented mutation in the family, positive changes in family relationships were reported, specifically greater expressiveness and cohesion, compared with those who pursued testing.[32]

Participation in breast cancer risk counseling among relatives of breast cancer patients is positively associated with higher levels of education, income, and positive health behaviors (nonsmokers, any current alcohol use, recent clinical breast exam), and perceived and objective risk perception.[33,34] Other predictors of participation are being married, having a family history of cancer, presence of a daughter, fear of stigma, and believing there are more reasons to be tested than not to be tested.[35]

Women recruited from high-risk clinics who have expressed their concern about breast cancer by seeking specialized medical attention are more likely than women recruited from registry sources to attend counseling and educational sessions about cancer genetics and genetic testing.[19,36] Genetic testing uptake was influenced by eligibility for free testing, history of breast or ovarian cancer, and Ashkenazi Jewish heritage.[17] Interest in testing declines sharply if it is not immediately available.[19] Knowledge about the details of cancer genetic testing is not associated with the decision to be tested,[37] suggesting a need for improved education about cancer genetics. Several studies suggest that interest in cancer genetic testing is generally high despite respondents' relative lack of knowledge regarding the pros and cons of attempting to learn one's mutation status.[34] One U.K. study suggested that proactive approaches to offering predictive testing (telephone calls and home visits) may be useful in increasing testing uptake among at-risk men.[38]

There are limited data on uptake of genetic counseling and testing among nonwhite populations, and further research will be needed to define factors influencing uptake in these populations.[36] In a study of African American women at increased risk of breast cancer, those with a personal history of cancer or a greater perceived risk of developing cancer were more likely to report greater limitations or drawbacks of genetic testing. Those with more fatalistic beliefs about cancer, higher perceived risk of having a BRCA1/BRCA2 mutation, and more relatives affected with breast or ovarian cancer were more likely to consider undergoing BRCA1/BRCA2 testing.[39] In a case-control study of women who had been seen in a university-based primary care system, African-American women with a family history of breast or ovarian cancer were less likely to undergo BRCA1/BRCA2 testing compared with white women who had similar histories. Other predictors of testing used in that study include younger age, higher anxiety, belief that testing will provide reassurance, absence of concern about discrimination, and having had a primary care doctor or gynecologist discuss genetic testing with the patient.[40]
