Psychosocial Outcomes and Contralateral Prophylactic Mastectomy (CPM)

With your verbal permission, you may have been asked to complete a questionnaire about your
surgical treatment preferences for breast cancer as part of initial screening for this study.
This takes about 5 minutes to complete.

If you agree to participate in this study, during the same visit you will complete a
questionnaire about your background, such as your education level, marital status, and family
history of cancer. This should take about 3 minutes to complete.

You will also be asked to complete a questionnaire about your surgery decisions and your
feelings about those decisions at the following times: around the time you enroll in study
before your surgery, and again about 1, 6, 12, and 18 months after the surgery is completed.
This questionnaire should take about 30-40 minutes to complete each time. You may complete
this questionnaire at the clinic or you may complete it at home. If you chose to complete the
questionnaire at home, you will be given a postage-paid envelope to mail it back to the study
staff.
