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".
