28. The same is true in regard to the treatment of the disease by means other than those mentioned: the earlier the morbid process leading to tumor formation is attacked by dietetic, hygienic, and medicinal measures, the greater the promise and expectation of success, present and permanent. 29. The prevention of cancer, therefore, or the checking of its increasing occurrence, depends largely upon the early enough adoption of such measures as will limit the agencies which induce a derangement of the body juices which tend to bad nutrition and derangement of the body cells. 30. The simple life, with the avoidance of the dietetic and other causes which have been found to induce cancer in nations and individuals, promises the best hope for the arrest of the rapidly increasing development of cancer throughout the world. 31. It is more than possible, however, that the long continued operation of many baneful causes has produced such a degeneration of tissue in the human race, that it will take a generation or more of proper living to make the beneficial impression on the general incidence of cancer which is so longed for.
