Page 30 - No, a thousand times no; there does not exist a category of science to which one can give the name applied science. There are science and the applications of science, bound together as the fruit to the tree which bears it.
Page 14 - A systematic procedure of inspection before a mirror, and gentle palpation has been developed by the American Cancer Society. Periodic examinations of the skin, mouth and genitals are also useful. Men should know the normal size and consistency of their testes, and check them for enlargement, hardness or irregular contour. Under conditions as they exist at present, most cancers are diagnosed because an individual becomes aware of certain symptoms, or because a physician suspects that certain symptoms...
Page 97 - The best design for these studies is one in which neither the patient nor the physician knows whether the patient is getting one or another drug. This is known as a "double-blind
Page 102 - The disease of cancer will be banished from life by calm, unhurrying, persistent men and women, working, with every shiver of feeling controlled and suppressed, in hospitals and laboratories.

Page 48 - Government life insurance policy holders. All reached the same conclusions. Deaths from all causes were increased among smokers, according to the amount smoked, particularly if cigarettes were used; the most striking proportional rise was in lung cancer. With these epidemiological clues in hand, scientists began to study the relationship in the laboratory. Chemists isolated and identified at least a dozen carcinogenic chemicals of the hydrocarbon type in the "tars" from tobacco smoke. The action...
Page 58 - The scientific approach to disease assumes multiple factors, some more proximate, some more distant in time; some more specific, some more general in their effects; some necessary, but not in themselves sufficient to bring about the condition of disease. We may qualify the role of any factor by...
Page 3 - Its main characteristics include an abnormal, seemingly unrestricted growth of body cells, with the resultant mass compressing, invading and destroying contiguous normal tissues. Cancer cells then break off or leave the original mass and are carried by the blood or lymph to distant sites of the body. There they set up secondary colonies, or metastases, further invading and destroying the organs that are involved.
Page 3 - This semi- independent behavior of cancer cells, in contrast to the disciplined behavior of normal cells that allows them to fulfill functions useful to the body, is called autonomy. Another important characteristic of cancer is its appearance under the microscope. The individual cells vary in size and shape, and the orderly orientation of normal cells is replaced by disorganization that may be so complete that no recognizable structures remain. This loss of normal appearance is called anaplasia....
