OBJECTIVE: To evaluate the risks, benefits, and utility of testing for adult-onset hereditary breast and ovarian cancer (HBOC) in adolescents and young adults.

STUDY DESIGN: We evaluated interest in genetic testing of adolescents for adult-onset HBOC genes through semistructured interviews with mothers and adolescents who had previously participated in breast cancer research or had pursued (mothers) clinical testing for HBOC.

RESULTS: The majority of mothers (73%) and daughters (75%) were interested in the daughter having genetic testing and were motivated by the future medical utility and current social utility of relieving anxiety and allowing them to prepare. Mothers and daughters both reported that approximately 3 years in the future was the best time to test the daughter regardless of the current age of the daughter. Overall, both mothers and daughters expressed the importance of the involvement of the mother to provide educational and emotional support but ultimately it was the daughter's decision to test. Balancing the independence and maturity of the daughter while reinforcing communication and support within the dyad was a prominent theme throughout the interviews.

CONCLUSIONS: There is interest among some high-risk adolescents and young adults to engage in genetic counseling and undergo testing. Providing pretest and posttest genetic counseling, assessing preferences for parent involvement, and offering psychosocial support may be important if genetic testing for HBOC is offered to adolescents and young adults before age 25 years.

<p><strong>PURPOSE: </strong>To compare health behaviors (smoking, alcohol use, fruit and vegetable intake, and exercise frequency) and breast self-exam (BSE) between girls with breast cancer family history (BCFH+) and without (BCFH-) and assess associates of behaviors across all girls.</p>

<p><strong>METHODS: </strong>A total of 208 BCFH+ girls (11-19years old), with first- or second-degree relatives with breast cancer or a mother with a BRCA1/2 mutation, and 112 BCFH- peers reported their health behaviors, beliefs, and psychosocial function.</p>

<p><strong>RESULTS: </strong>Despite higher BCFH+ girls' greater perceived breast cancer risk, there were no differences between BCFH+ and BCFH- girls on diet, exercise, alcohol initiation, or BSE. BCFH+ girls were slightly more likely to report trying cigarettes (11% vs. 5%, p = .04). In multivariable models with all girls, categorical associations with behaviors included the following: developmental and demographic factors with smoking, alcohol, diet, and exercise; family breast cancer history and experience with smoking, alcohol, and diet; psychosocial factors with smoking; girls perceptions of cancer controllability and mother support for health behaviors with alcohol, diet, exercise, and BSE; and mother behaviors with diet.</p>

<p><strong>CONCLUSIONS: </strong>Adolescent girls from BCFH+ families reported similar health behaviors to BCFH- peers, signaling that they are not translating their higher perceived risk into cancer controlbehaviors. Both uncontrollable (i.e., breast cancer experiences) and modifiable factors relate to health behaviors and warrant further investigation. Results indicate that interventions with teens and parents that target modifiable variables such as controllability perceptions, maternal modeling, and communication may relate to better health behaviors and reduced future breast cancer risk.</p>

<p><strong>PURPOSE: </strong>To evaluate the impact of breast cancer family history and maternal BRCA1/2 mutation on the psychosocial adjustment and perceived risk in girls age 11 to 19 years old.</p>

<p><strong>MATERIALS AND METHODS: </strong>Girls age 11 to 19 years old with one or more relatives with breast cancer or a familial BRCA1/2 mutation (breast cancer family history [BCFH] positive, n = 208; n = 69 with BRCA1/2-positive mother), peers (BCFH negative, n = 112), and their mothers completed assessments of psychosocial adjustment, breast cancer-specific distress, and perceived risk of breast cancer.</p>

<p><strong>RESULTS: </strong>General psychosocial adjustment did not differ significantly between BCFH-positive and BCFH-negative girls, either by self-report or mother report, except for higher self-esteem among BCFH-positive girls (P = .01). BCFH-positive girls had higher breast cancer-specific distress than BCFH-negative girls (P &lt; .001), but girls from BRCA1/2-positive families did not differ from other BCFH-positive peers. BCFH-positive girls were more likely to report themselves at increased self-risk for breast cancer in adulthood than BCFH-negative peers (74% v 33%, respectively; P ≤ .001). Girls from BRCA1/2-positive families were more likely than other BCFH-positive and BCFH-negative peers to report themselves at increased risk (P &lt; .001). In all groups, perceived risk of breast cancer was associated with older age. Higher breast cancer-specific distress among adolescent girls was associated with higher self-perceived risk of breast cancer and higher maternal breast cancer-specific distress.</p>

<p><strong>CONCLUSION: </strong>Adolescent girls from BRCA1/2-positive and breast cancer families have higher self-esteem and do not have poorer psychosocial adjustment than peers. However, they do experience greater breast cancer-specific distress and perceived risk of breast cancer, particularly among older girls. Understanding the impact is important to optimize responses to growing up in families at familial and genetic risk for breast cancer, particularly given the debate over the genetic testing of children for cancer susceptibility in adulthood.</p>
