The goal of this prospective, case-control study is to discover the specific omics biomarkers of early stage of lung cancer using the non-invasive samples (breath, urine and serum) in a total of 200 subjects (100 healthy controls and 100 lung cancer patient). The main questions it aims to answer are: * Which are the omics biomarkers that characterize the early stage of lung cancer? * How to Translate Laboratory Data into Clinical Data? For each participant we will collected the breath, urine and blood samples. In lung cancer patients group the samples will be sample before lung cancer resection. The samples of Breath, urine and serum will be analysed using different type of analysis: eNose and the Gas Chromatography combined with Ion Mass Spectrometry (GC/IMS). Moreover, Serum will be analyzed by mass-spectrometry-based proteomics. The purpose of these analyses will be to find biomarkers capable of distinguishing the early-stage of lung cancer from the healthy group. Followup will be performed to evaluate the possible change of the volatolomic and proteomic profile.
