Chronic edema/lymphedema affects more than one million Canadians. New basic research shows that all chronic edema involves lymphatic dysfunction. This webinar will discuss the pathophysiology of lymphedema and the underlying risk factors. The Canadian Lymphedema Framework has used these risk factors to estimate the prevalence of lymphedema in Canada. Several Canadian studies have described the characteristics of those people living with lymphedema. In this presentation we will also introduce a series of webinars designed by the Canadian Lymphedema Framework for health care professionals.
