Brief Summary

This study is designed to determine the impact of a novel genetic counseling method on surgical decisions in individuals with newly diagnosed breast cancer This research study involves an expedited and surgery-specific form of genetic counseling. The names of the study methods involved in this trial are/is:

  • Quantitative genetic counseling (discussion is guided by tables and graphs)
  • Standard genetic counseling

Outcome Measures

Primary Outcomes (2)

  • Change in patient's assessment of their personal contralateral breast cancer risk

    A short survey, self-developed in conjunction with the Dana Farber Cancer Institute professional survey core, will be used to compare changes in patients' personal contralateral breast cancer (CBC) risk assessment after quantitative versus standard genetic counseling. The question reads: "By the time you turn 80 years old, what do you believe is the chance you will develop cancer in the other (unaffected) breast?" and answer options are in 10% increments (ie. 0-10%, 11-20%, 21-30%). Their individual assessment of their risk will be collected before and after genetic counseling and will be compared to CBCRisk (for those without gene mutations) or ASK2ME (for those with gene mutations).

    1 month

  • Change in patient's propensity to choose bilateral mastectomy as determined by a short self-developed survey question

    Patient's will be surveyed about their personal propensity to choose a bilateral mastectomy as the surgical treatment of a unilateral cancer before and after quantitative vs. standard counseling. This survey question was self-developed in conjunction with the Dana Farber Cancer Institute professional survey core. The question reads: "How likely or unlikely are you to choose surgery to remove both breasts (bilateral mastectomy) for your cancer in one breast (unilateral or one-sided breast cancer)?"s answer options include the following: "Very unlikely, Somewhat unlikely, Unsure (neither likely nor unlikely), Somewhat likely, Very likely).

  • Contralateral Prophylactic Mastectomy (CPM) Rate

    6 Months

  • Level of anxiety among participants, as measured by the PROMIS anxiety scale

  • Number of participants with decisional regret (testing and surgery choices)
