Rare Disease Day takes place on the last day of February each year. The main objective of Rare Disease Day is to raise awareness among the general public and decision-makers about rare diseases and their impact on patients' lives.

Mastocytosis is described as a rare disease, but the exact incidence and prevalence are not known.  According to the Genetic and Rare Disease Information Centre, an estimated prevalence is approximately 1 case per 10,000 people.  Mast Cell Activation Syndrome (MCAS) is thought to be more common but difficult to diagnose, thus often goes under-diagnosed.  

Please help us raise awareness of Mast Cell Disease. Raising awareness improves knowledge and encourages researchers and decision makers to address the needs of those living with rare diseases.  Hopefully, this will lead to better diagnostic testing, improved treatment options and eventually, a cure.  



You can help raise awareness!
