Medicine: Malignant Growth

Cancer is becoming commoner in the U.S. The National Cancer Institute, studying first reports on a ten-year checkup in ten sample areas, estimated last week that from 1937 to 1947 the number of new cancer cases in the country increased 34%. Of this, only 7% was due to the fact that more people were reaching the older age groups where cancer strikes oftenest. Of all types of malignancy, lung cancer was increasing fastest.
