Carcinoma of the Colon and Rectum

Abstract

CARCINOMA of the colon and rectum is now the most common type of malignant tumor other than cancer of the skin. It is moreover one of the varieties to which a great deal of attention has been devoted in an attempt to control cancer, since a change in bowel habit and rectal bleeding have been emphasized repeatedly in the past decade as the prime warning symptoms of internal cancer.The importance of this type of neoplastic disease is shown by the estimate that in the United States, in 1961, there will be 70,000 new cases of cancer of the colon . . .
