Hi am wondering if when getting a second opinon how often does a person diagnosed with cancer does the sceond opinon caome back negitive of cancer?

Rare: When the diagnosis of cancer is made and a second opinion is called for it is rare that there is no neoplasm present. The major reason for second opinions in cancer is to define the nature of the malignancy if bx not yet obtained. More often it relates to the nature of the procedure needed for removal of the tumor or if the neoplasm is resectable due to extent of surrounding involvement.
