19.
Carcinoma of the Lung. Deaths from broncho - genic carcinoma are reported to
have increased 500% since 1930.
Figures for this Unit show the number of cases discovered
1951 - 2 1954 - 12
1952 - 6 1955 - 10
1953 - 7 1956 - 11
1957 - 13
Compared with other Units, the above figures are on the low side which
may be explained by the fact that apart from some pollution of the atmosphere
by the internal combuston engine and cigarettes smoking there are no added
industrial hazards in the City of London.
It should be noted that asymptomatic carcinoma will often show no
abnormal radiological shadows. To illustrate this problem let me quote two
recent cases. A man (age - 60) was referred on account of a small haemoptysis
in October 1957 and thoroughly investigated at one of the teaching hospitals
with a negative result; in December he developed cerebral metastases. Another
man (age - 66) had a miniature film at the end of February which was clear;
two months later he developed a growth in his right upper lobe.
Most of the cancers picked up by Mass Radiography Units were cases
referred by general practitioners on account of symptoms. Up to the end of
1957 general practitioners have not utilised the services of our Unit so fully
as might have been expected, but a revised procedure introduced early in 1958 has
produced a greater response.
Propaganda. Propaganda in the form of posters and leaflets is only occasionally
employed, as approach to firms, etc., is made either by personal contact or by
special letters, of which the Unit now has a series.
Staff. Several changes in the technical and clerical staff occurred during 1957.
I would like to record my gratitude for the wholehearted support rendered by all
mombers of the staff during the year.
Conclusion. During 1958 the Unit received visits from several medical students
from overseas who were in 'this country under the auspices of the National
Association for the Prevention of Tuberculosis.
Friendly relationships have existed between the Unit and Dr.J.Greenwood
Wilson, Medical Officer of Health for the City of London, and with the Medical
Officers of Health for the Boroughs of Finsbury and Shoreditch. Helpful cooperation
has been shown by the London County Council and the Divisional Medical
Officers in Health Divisions 3, 4 and 5. Our gratitude must be accorded to the
Central Group, Hospital Managanent Committee and to the Regional Hospital Board,
for the many services rendered to the Unit during the year".
