During a diagnosis for lung cancer, doctors gather comprehensive data. During lung cancer diagnostic sessions, details on a person’s lifestyle, medical history, work, prevailing unhealthy habits, viz., drug consumption, smoking, etc. are gathered by doctors. Additionally, the person undergoing lung cancer diagnosis will be asked questions about whether his/her family has a lung cancer history, as well as possible earlier/current exposure to work-related hazards, like harmful gases, radiation and other hazardous materials.
