Comments on Foregoing Table.
The two main groups of organs attacked in both sexes are
the alimentary system and the reproductive system. In males 33
per cent of the total deaths fall within these groups and in females
50.6 per cent. In males Cancer of the digestive system is the
commonest situation, amounting to 30 per cent. In females it was
26.6 per cent. Cancer of the reproductive system caused 24 per
cent. of the total deaths in females and was the most prevalent
type. Cancer of the larynx, tongue and mouth is commoner in
males than females, 12 deaths occurring in males as compared with.
3 in females. The organs most often attacked in descending order
of incidence are, in males the Rectum and Bowels (33.15 per cent.) ;
the Stomach (16.8 per cent.) ; the Lungs (12.0 per cent.) ; the
Prostate (6.5 per cent.) ; the Pancreas (6.5 per cent.) ; in females,
the Bowels and Rectum (21.1 per cent.) ; the Breast (19.4 per
cent.); the Uterus (18.1 per cent), and the Stomach (13.9 per
cent.). This is slightly different from the incidence in 1936. There
has been a noticeable increase in the number of deaths attributed to
Carcinoma of the Bowel and Rectum and Carcinoma of the Uterus,
and an equally noticeable decrease in the number of deaths attributed
to Carcinoma of the Stomach and Carcinoma of the Breast.
The main incidence of Cancer is, in both sexes, on two groups
of organs, both having a common characteristic, namely, periods
of active cell degeneration and regeneration.
