2015 The year 2014 marked the 40th anniversary of the International Association of the Study of Lung Cancer (IASLC), a global organization that works to enhance the understanding of lung cancer among scientists, members of the medical community, and the public.* MASCC and IASLC frequently collaborate to address the challenges of lung cancer, its symptoms, including cough and breathlessness, and their management. The new MASCC Respiratory Study Group has identified breathlessness as its first priority for developing evidence-based guidelines.
