      In Mexico, lung cancer is the seventh in incidence and first in mortality. Diagnosis in advanced stages accounts >70% of cases. We analyze factors associated with a late diagnosis and delay in the beginning of treatment.

An interview was conducted to identify: 1) onset of symptoms, 2) time elapsed to seek medical attention, 3) number of doctors visited, 4) diagnosis established prior to cancer diagnosis pulmonary, 5) time elapsed from diagnosis of cancer until admission to INCan and 6) Time elapsed from diagnosis to start treatment.

      In Mexico, lung cancer is diagnosed in advanced stages due to a lack of clinical suspicion in primary care physicians. Delay from initial medical assessment to specialized center referral is considered an opportunity window. Identification of these factors will lead to establishment of public health policies that ensures improvement of diagnostic approach and the timely reference and initiation of treatment in specialized centers to improve the prognosis.
