Back to the Curies. Primitive variations of the treatment chosen by Blaschko date back to the turn of the century, when the Curies' discovery of radium made possible a radiation source compact enough to be placed within a tumor. Since then, the technique has been considerably refined and has long been used to treat certain cancers of the neck, head, vagina and other parts of the body difficult to cope with surgically. Now, U.S. doctors, confronted by 90,000 new cases of the disease a year, are showing an increased interest in the use of interstitial implants against breast...
...sense of horror builds so slowly the movie passes like a bad dream. Farrow gives a jittery, flittery performance; I leave it to you to place the blame--can she act, or is it merely what she has to work with? This film goes over like a brain tumor--avoid at all costs...
...experiment that is causing great concern and is restricted to quite special facilities: the so-called "shotgun" experiment with random fragments of DNA from animal cells. Two considerations seem pertinent. First, the probability that any fragment will contain a gene for a toxic product, or the genes of a tumor virus, is exceedingly low, though not zero. Second, evolutionary considerations provide an independent approach to the question. It seems exceedingly doubtful that our novel ability to introduce mammalian DNA into bacteria in the laboratory will create a truly novel class of organisms, for evolution has already had a crack...
...accept uncritically the studies and test data provided by the pesticide producers themselves-and for its failure, in many cases, to consider adverse reports and warnings from experts. The EPA, for example, ignored a report in its own files showing that the pesticide 2,4-D caused "increased tumor formation" in rats; as recently as April 1976 it approved what many experts believe to be unacceptably high tolerance levels of the chemical in food products. The agency was also blasted for dragging its feet on aldrin, dieldrin and heptachlor. An EPA review revealed as early as 1971 that there were...
Following the British lead, Houston's M.D. Anderson Hospital and Tumor Institute, the U.S. Naval Research Lab, and the University of Washington in Seattle have all started using neutron irradiation. But Fermilab has a special advantage: it delivers neutrons at higher energies and thus can probe deeper into the tumors...
