A second medical opinion refers to resolving difficult problems incurred in connection with the diagnostics or therapy related to a given illness by involving an external professional. When using this service, by consulting an independent specialist, the patient obtains confirmation as to whether the previous diagnostics or the therapy planned or in progress is appropriate or not. This objective professional control is more than providing a simple confirmation; it also ensures that the most advanced examination and treatment principles are applied. The great advantage it offers is that it reinforces trust between doctor and patient.
