"Medical second opinion" is the dominant term for the description of remote medical opinion services. It is important for search engines, but we consider "second opinion" term misleading. This is why. A patient and their family might feel "mission accomplished" when they have received a "second opinion" somewhere, irrespective of what was contained in that "second opinion". That is not necessarily true. The goal of every patient is to obtain not only generally correct, but also precise and complete diagnosis. Then every patient's goal shifts to obtaining the best possible treatment, which will hopefully result in the best possible prognosis. Many patients have a diagnosis that is too broadly defined or not precise enough. Consider a diagnosis "estrogen receptor-positive breast cancer" or "severe mitral valve prolapse". This is not precise enough for a precision medicine era. These diagnoses might have been considered sufficiently precise yesterday. But today, that is not true. There must be a precise molecular and / or quantitative functional characterization of current stage of pathological process. This characterization has to be accomplished by mulitple modern modalities of diagnostic testing. Only then it is possible to provide a precision medicine-based treatment plan, to ascertain the most likely prognosis, and to determine how to improve the prognosis. It may take one expert opinion or it make take ten expert opinions to get to the most precise characterization of the disease and the best possible treatment plan. It takes a MultiDisciplinary Team [MDT] discussion by experts who precisely fit patient's clinical situation. They have to weigh all treatment options appropriately. Just because a group of physicians in any hospital calls themselves a "tumor board" or a "MultiDisciplinary Team", it does not automaticlaly mean that they are the best experts for a given patient. They might be good for one patient but not good enough for the next patient. That has to be understood by all patients. And the term "second opinion" potentially glosses over such crucial nuance. Getting the best treatment plan possible is not about the semantics and fancy words. It's about the depth of expertise of doctors. It's about how closely the knowledge of a surgeon or a medical specialist fits the nuances of patient's specific medical situation. That brings the best outcome of treatment for any patient. That's why we prefer to use the term "medical expert opinion" to describe our services. Precision matters!
