In recent years, the incidence of bronchopulmonary cancer (PBC) in young people has increased. Our objectives were to specify the different risk factors and to identify the clinical, histological and evolutionary characteristics of primary PBC in this population. Smoking is the main risk factor for PBC in young people. It remains the main target for prevention. However, the contribution of other risk factors should be studied in order to broaden the therapeutic modalities. One of the particularities of PBC in the young is a relatively late diagnosis compared to older subjects. Most are diagnosed at a metastatic stage. To overcome this problem it is necessary to facilitate access to care and to improve the social coverage of patients. In addition, it is important to raise awareness among the young population, especially among smokers, so that they can be consulted at the earliest possible stage. It is therefore important for the primary care physician to be aware of PBC in young people, especially among smokers, in order to allow for an earlier diagnosis.
