Lung cancer is as old as man. Although the lungs are a frequent site of metastasis from cancers originating in extrathoracic organs.A prospective longitudinal descriptive observational study was carried out in the Pulmonology service of the Arnaldo Milian Castro Hospital in the period from October 2020 to October 2023. The study population was made up of all patients (110) diagnosed with this disease. Patients with lung cancer were diagnosed in 2020, female, white, retired, between 60 and 69 years old. Cough was the main symptom, with smoking being a risk factor for its presentation. Infiltrating poorly differentiated squamous cell carcinoma is more common.
