...Hubert H. Humphrey, 66, indefatigable Minnesota Senator, former Vice President, and 1968 standard-bearer of the Democratic Party; with inoperable pelvic cancer; in Minneapolis. Doctors discovered a malignant tumor on Humphrey's pelvic bone during a four-hour operation to remedy a bowel obstruction. The Senator's cancerous bladder was removed last October. Although his condition is described as terminal because it is inoperable, doctors refused to say how long he might live. They plan to treat the tumor with chemotherapy to slow its growth, and expect that Humphrey will be able to return to the Senate...
...same electronic wizardry that was enabling him to tune in to microwaves from free-floating molecules in interstellar space could have a down-to-earth application. If they were reduced in size, he reasoned, the sensitive antennas could even pick up the weak microwave (or heat) emissions from a tumor...
Because of its rapid rate of growth and increased blood supply, a tumor is hotter than normal tissue and hence gives off more radiant energy. Thermography, or heat scanning, concentrates on looking for infra-red radiation to find tumors. But such waves are rapidly absorbed by bodily tissue; thus tumors that lie any distance below the skin's surface cannot be readily picked up by infra-red sensors. By contrast, microwaves-which are much longer and more penetrating-can locate tumors up to 10 cm. (4 in.) below the surface...
