Generally, insurance pays for a second opinion. (It’s to their benefit to get the right diagnosis, so they pay).
The Mayo Clinic, Cleveland Clinic, and MD Anderson all do second opinions. I checked all their sites. I’m sure Sloan Kettering does it, too. It may take 3 days to 2 weeks. That probably depends on what they need to look at (real biopsy tissue, or images - they priority special mail biopsies between facilities) MD Anderson says it’s a basic $272 for a review of pathology. You would need to discuss with any of them whether they need to do their own biopsy, or can view what has already been done.
I switched from a local Baylor Scott & White hospital to MD Anderson (not because BSW couldn’t do a good job, but I live near enough to MDA, so it was a nobrainer choice).
I contacted MD Anderson on their website where it said “do you want to be a patient?” It felt weird to do this, but I didn’t have any other resource contacts. They immediately jumped on board, ordered all my old mammograms, reviewed the biopsy report (from BSW) and within a week I was scheduled to start down the BC road.
I’m sure all the major comprehensive cancer centers do similar procedures. It’s amazing how easy it was for me - they knew what info and reports they needed, and it was done. They actually viewed the full BSW pathology report before I did because they were part of the “share everywhere” medical records, and I approved them to access mine.
Best of wishes! If you need a friend to “stand” beside you - you’ve got one! And many more on this site!
