A single speaker explains how Western medical education has historically treated mast cell disorders as rare, why that assumption is incorrect, and how clinicians often fail to recognize or consider mast cell activation issues—typically referring patients to allergy/immunology—so MCAS is underdiagnosed. The excerpt is an informational/explanatory talk about clinical recognition and prevalence of mast cell–related conditions.
