International Mast Cell Disease Awareness Month

Join us in marking a historic milestone - the inaugural International Mast Cell Disease Awareness Month!

Throughout this dedicated month, we're shining a spotlight on mast cell diseases, fostering understanding, and igniting conversations worldwide.

From rare conditions like mastocytosis to the increasingly more common MCAS, these diseases affect many people globally.

Through education, advocacy, and support, together, we can make a difference. Let's raise awareness, inspire hope, and empower those impacted by mast cell diseases.

Even better, ask friends, family and colleagues to support your creations by sponsoring your craft sessions! Set up your JustGiving page here.

You could come along to our creative session with superstar volunteer Alice to join others with MCAS or suspected MCAS who enjoy being creative together.

Please share your creations with us using the #mcascreativechallenge and tag us @mastcellaction.
