Former Phillies pitcher Larry Andersen and Fox News Medical contributor Dr. Marc Siegel on six former Phillies players dying of brain cancer.

Fox News medical contributor Dr. Marc Siegel said on Wednesday a string of brain cancer deaths of former Philadelphia Phillies players must be investigated.
