Why a second opinion matters for breast cancer
The most common cancer in women in the U.S. Clinical trials test new therapies for early-stage, locally advanced, and metastatic breast cancer.
Breast Cancer treatment plans often involve multiple options — systemic therapy, surgery, radiation, immunotherapy, or combinations. A second opinion from a subspecialty expert can confirm the diagnosis, validate the plan, or introduce clinical-trial options you might not otherwise learn about.
What to prepare
- Pathology report and, if possible, pathology slides for re-review
- Imaging studies (CT, MRI, PET, ultrasound) on disc or via secure portal
- Operative notes (if you've had surgery)
- List of current medications and treatment history
- Name and contact info for your current oncologist
Where to get a breast cancer second opinion
Start with an NCI-designated cancer center — these institutions are recognized by the National Cancer Institute for research-led oncology care and typically have the deepest breast cancer subspecialty expertise. Most offer virtual second-opinion programs.
Look for: major comprehensive centers like MD Anderson, Memorial Sloan Kettering, Dana-Farber, Mayo Clinic, and Johns Hopkins; and regional NCI centers in your state (browse the full list).
