Leading cancer hospitals often offer the ability to get a second opinion by submitting your information electronically.

If you have any question about how your cancer is being treated, get a second opinion from a leading cancer center. You may want to link to a center close to you in the event you decide to go to that facility. Search that center name and "electronic second opinion".

Here's information from Dana Farber Cancer Institute. https://www.dana-farber.org/appointments-and-second-opinions/online-second-opinion-program/

I understand there is a $2,000 charge from Dana Farber for this.
