Responding to recent warnings that breast X rays, or mammograms, may be contributing, however slightly, to the incidence of breast cancer (TIME, Aug. 2), health officials last week issued new guidelines for their use in a breast-cancer screening program in 27 centers for women 35 years and over...
Until now, the 270,000 participants in the demonstration project-a joint effort of the National Cancer Institute and the American Cancer Society-automatically received annual mammograms, along with a manual examination of the breasts and thermograms (tumor-detecting heat pictures). But under the new policy, mammograms will be restricted, until further studies are completed, to women 50 and above-an age group known to have profited from them-and others who have a greater than ordinary risk of breast cancer: women who have a family history of the disease, have lumps or pains in their chests or have reached...
...fear of breast cancer among American women is understandably great. As the commonest cause of death among women, it kills 32,000 yearly in the U.S., and any report of increased risk raises the level of alarm. This happened last week when the New England Journal of Medicine published a report that women who take estrogen drugs after the menopause to replace natural hormones run a greater risk of breast cancer than others. The cautionary conclusion was based on a study of 1,891 Louisville women. Of those studied, 1,028 or slightly more than half, had had their ovaries...
...authors, headed by Dr. Robert Hoover of the National Cancer Institute, conceded that the statistics must be examined with caution. But the general conclusion was clear: while the incidence of breast cancer changes imperceptibly if at all during the first few years on estrogen medication, it may rise sharply after ten years and it almost doubles after 15 years. But duration of treatment is not the only factor. The doses taken and the dosage schedule are also important. Harvard Gynecologist Robert Kistner reviewed the latest report judiciously. "Estrogen must be used selectively in postmenopausal women," he said. "Only patients with...
