The Mercy Breast Cancer Second Opinion Program is available to patients who have received an initial breast cancer diagnosis at another health care provider and wish to obtain a second opinion on the recommended treatment approach for their specific diagnosis. Data shows that of patients who seek a second opinion, 37% have a change in their treatment plan, and the actual diagnosis for these patients changes about 15% of the time.

Each Mercy second opinion patient will be assigned a breast nurse navigator specially trained in breast cancer. The nurse navigator will contact you by phone to discuss your case and determine which appointments are needed.

Second Opinion appointments are held the second and fourth Monday of each month at 15945 Clayton Road in Ballwin Missouri (at the intersection of Clayton and Clarkson Roads).
