But studies suggest women who need breast cancer surgery have better outcomes if they see surgeons highly experienced in the kind of surgery they need.
In their study, Steven Katz, MD, MPH, and colleagues surveyed 1,844 women diagnosed with breast cancer. Katz is director of health services research at the University of Michigan Comprehensive Cancer Center.
The researchers found that only a third of the women were treated by a high-volume surgeon -- one with more than 50% of his practice devoted to breast cancer surgery.
Women who said they chose their own surgeon were twice as likely to see a highly experienced surgeon as were those referred by another doctor or by their health plan.
"Women who were more actively involved in selecting their surgeon were more likely to be treated by surgeons more experienced in breast surgery and in more comprehensive treatment settings," Katz and colleagues report.
"By contrast, the provider-based referral pathway was not associated with surgeon volume [in breast cancer surgeries]," the researchers say.
They advise women to get a second opinion -- especially if their doctor recommends a specific procedure without a full discussion of the options.
Katz and colleagues report their findings in the Jan. 20 issue of the Journal of Clinical Oncology.
