Lung cancer is the leading cause of cancer death in men. Its incidence increases by 5.6% per year in women, all age groups are affected. This is a descriptive retrospective study from January 2013 to December 2022 involving 58 patients hospitalized for primary bronchial carcinoma, in the respiratory disease department of the August 20 hospital in Casablanca. The average age found was 56 years with extremes ranging from 21 to 65 years, 20% of patients were active smokers, passive smoking was found in 25% of patients, no detectable occupational exposure, all patients were symptomatic at the first consultation with an average time between the onset of symptoms and hospitalization of 2.5 months. The main symptoms found are respectively; dyspnea in 89% of cases, dry cough in 80% of cases and chest pain in 75% of cases. Radiologically, peripheral parenchymal involvement represents 80% of radiological images. Bronchial endoscopy showed a tumor bud appearance in 36% of cases and tumor-like infiltration in 32% of cases. Histological proof is obtained by bronchial biopsies in 42% of cases, by PBP in 32% and by PBTP in 26% of cases. Adenocarcinoma is the most frequent histological type (54%). Sixty-two percent of cases are in stages IIIB-IV. Eleven percent of (CBP) in women are operable immediately, 38% benefited from neoadjuvant chemotherapy, 16% from palliative chemotherapy and 35% from symptomatic treatment. Primary lung cancer is a reality whose main cause is the increase in female smoking. Smoking is no longer the only risk factor for lung cancer in women, genetic, constitutional and hormonal factors seem to interfere in women. However, bronchial cancer remains a late discovery and a reserved prognosis.
