This book is a themed collection of previously published articles that address these topics and will help surgeons navigate this potentially complex and more increasingly common clinical situation to optimally treat their patients. The book is divided into four sections, outlining prognostic features, diagnostic advances, treatment options, and GGO related risks. The readers should gain understanding in the variety of tools that we have at our disposal to both diagnose and prognosticate these lesions, as well as the interventions available to manage concerning, high-risk lesions. This resource will be valuable to not only thoracic surgeons, but all practitioners who take care of patients who are found to have a GGO. The ultimate beneficiary will be each patient whose care is individualized to optimize their long-term prognosis while limiting any potential morbidity of treatment.
