A prospective, multicenter was conducted in all specialized centers in the city of Dakar. The objective was to describe the epidemiology to assess the management of lung cancer. 45 patients were included. The sex ratio M/F = 8. The average age of patients was 57.5 years. Smoking was found in 84.4% of cases. The average time for consultation after the onset of symptoms was 6 months. The average time to diagnosis was 2 months. Two out of three patients (66%) had seen beyond the stage III B. Improved diagnostic performance for early diagnosis of cancer is needed. Emphasis should be on prevention through tobacco control.
