Medicine: Moving Cancer

In London last week, the members of the British Empire cancer campaign, which is functioning somewhat in the manner of the American Society for the Control of Cancer, heard described the slow motion photography of living cancer cells. A motion picture camera is focused on a cancer sore and operated slowly for varying periods up to two days. The long negative is developed and a positive film made. When the reel is projected on a screen the cancer cells, magnified, are seen spreading, moving, creeping, quite like budding flowers seen in slow motion pictures. The process is expected to reveal to cancer searchers many an unknown detail of the disease.
