...hormones that regulate the growth of ordinary cells. It multiplies wildly, growing into a useless mass of disorderly tissue. The tumor pushes among the normal cells, presses on nerves, thrusts organs aside or invades them. Often the gangster cells get into the blood and spread around the body like seeds carried by the wind. Where they lodge they grow into "metastases"-secondary tumors as lawless as the first...
...Nazis were rather like cancer," says Rhoads, growing philosophical as all scientists are apt to do when they think about cancer. "Starting with a variant cell, Hitler, the Nazis multiplied throughout the German nation, bringing it to destruction. It took external forces to kill the Nazi cancer...
Knife & Radiation. "External forces" are the business of Sloan-Kettering Institute and all the other centers of cancer research, which are spending something like $50 million in the U.S. annually. At present the only known cure for cancer is destruction: the surgeon's knife or radiation (X rays and radium). Such methods work well with some forms of cancer. Skin cancer, for instance, can nearly always be removed so completely that it does not recur. Other accessible cancers can be dealt with too, and surgical methods are improving constantly. A recent advance saves many patients who have a vital...
...trouble is that cancer cells are very like normal cells. An agent that hurts one generally hurts the other. Still, the gangster cells have differences. The very fact that they grow rapidly in a chemical medium, the blood, in which normal cells grow slowly, is sufficient proof that they are different. To find and exploit the differences is the chief goal of Sloan-Kettering Institute. The problem is being attacked at all levels-from simple testing of promising drugs to long-range exploration of the internal workings of cells...
Cell chemistry is a maddeningly complicated study. It is known that cells contain certain chemicals, but they are not mixed together haphazardly like dissolved salts in a chemist's beaker. Each cell is like a great, complex metropolis. The individual citizens (atoms) are organized into intricate groups like the people of the city. Some groupings (e.g., the three-atom molecule of water) are as small and tight as families. Others are larger, like all the workers in one factory. The various groups interact constantly, their links forming and dissolving as the cell lives and grows. Certain single large molecules...
