Brain cancer is a serious issue in the global burden of diseases. It is estimated that 3.24 million new cancer cases and 1.66 million cancer deaths will be registered across Europe in 2024 and 40,800 of these deaths are from brain and central nervous system (CNS) cancers. This COST Action aims to significantly facilitate the translation of fundamental scientific discoveries into better clinical treatment and management of patients suffering from brain cancer. We are still looking for new members and teams. If you are interested in, we are looking forward to hearing from you.
