Finding a cure for histiocytosis

The Histiocytosis Association of Canada is dedicated to improving the lives of Canadians affected by histiocytosis. We are focused on public and professional education, patient and family support, and stimulation of support of research. 

We are an international group of parents, patients, physicians and friends in search of a cure. 

We work  closely with an international group of physicians,  known as the Histiocyte Society, who are dedicated to studying the histiocytoses. Through this partnership, more has been learned and  better treatments have been discovered.

If you or someone you love has been diagnosed with histiocytosis, and you are looking for help, contact us today at info@histio.ca. You are not alone.
