Although there is no known cure for MCAD, most patients with indolent (benign) systemic mastocytosis can expect a near normal life expectancy if they are diagnosed and managed correctly, avoid triggers, and are always cognizant that they are at increased risk of anaphylaxis. The life expectancy of MCAS and CM and ISM patients is similar to that of the general population. Table II. ).
