...paper. Aside from polluting the land and water, the critics say, this vast consumption threatens to strip the earth of its resources. In the rhetoric of Paul Ehrlich, "America's pride in her growing population may be compared to a cancer patient's pride in his expanding tumor...
...women whose families had a history of the disease, six (60%) were found to harbor large numbers of the particles. Doctors are still reluctant to state flatly that these particles actually cause breast cancers in humans. They have been unable as yet to identify particles in a human tumor. But Moore has found that serum from humans who have had breast cancer can have a neutralizing effect on the mouse virus when the serum is injected into mice...
...blind" study,* conducted both in Camden and at Columbia, showed a 100% correlation between particle concentrations and the presence of an enzyme, or chemical catalyst, which is associated with viruses known to cause cancer in animals. The experiment also revealed two startling similarities between the virus-like particles and tumor-causing RNA viruses: both have the same density and both share the ability to reverse the normal order of genetic transmission. Spiegelman's and Schlom's conclusion is crucial. Normally, DNA, the double-helix master molecule, produces RNA, which carries genetic information to the cell (TIME, April...
...being put to even greater use by physicians seeking to plan treatment programs for their patients. Doctors at Mary Hitchcock Memorial Hospital in Hanover, N.H., have programmed their Honeywell computer to sort through some 20,000 different radiation-treatment plans and extract the ten most suitable for a particular tumor patient...
...unique series of experiments, Dr. Loren Humphrey of Atlanta's Emory University inoculated patients with a vaccine made, at least in part, with tissues taken from tumors similar to their own. He then followed up the inoculations by cross-injecting the patients with white blood cells from fellow patients who had presumably been sensitized to the tumor antigens. Though only long-term testing will tell if Humphrey's approach is effective, the preliminary results appear promising. One patient with bowel cancer has been free of the disease for three years, while three others have evidenced definite remissions...
