Rare Disease Day Banner


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!

Share your story!  We can drastically increase awareness of mast cell disease by telling others our story.  By sharing our story, we can:

  • help other patients feel they are not alone on this journey.
  • help our friends and family know what it's like to live with a rare, often debilitating disease.
  • help government officials and decision makers understand how they can improve health care for those with rare disease.  

Please share your story with us at blog@mastocytosis.ca.  With your permission, we would love to feature your story on our blog, or here on our website.
