In 1928–9 was published the result of an investigation into the incidence of tumours of the respiratory tract based on an analysis of the post-mortem records of the General Infirmary at Leeds between the years 1891 and 1927 inclusive. It was shown that there had been no increase in intrathoracic cancer at post-mortem during this period, that the incidence was not as high in Leeds as it was in Manchester and that the disease affected men more commonly than women in the proportion of 3½: 1. It was also shown that there was a general tendency towards an increase in lung cancer in post-mortem statistics of other hospitals, especially in Germany.
