Previous communications from this laboratory have provided evidence in favor of the theory that susceptibility to tumors of the mammary gland (1) and tumors of the lung (2) is inherited. This evidence is based upon observations of spontaneous tumors. The discovery and perfection of methods of inducing tumors of various kinds have demonstrated the important r61e played by chronic irritation in t...
