- This study is most relevant for women with breast cancer who are recommended to undergo a single mastectomy.
- This study is not relevant for women women with an inherited gene mutation linked to an increased risk for breast cancer.
- The study looked at survival outcomes only. They did not study the risk for a new breast cancer diagnosis in the other breast.
Strength of Science: Medium
- This study was retrospective, meaning that the researchers analyzed but did not collect the data used; information about the women that was unknown to the researchers could have otherwise affected the results.
- The percentages of long-term survival after CPM presented by this study are estimates calculated from the study’s modeling program. The researchers did not actually measure the 10-year survival rates for these women.
- Survival is an important outcome, but not the only outcome of interest to breast cancer patients.
- This study is not as relevant to young breast cancer survivors with an inherited mutation linked to increased risk for cancer.
