Breast cancer rise: due to dietary fat?Breast cancer rise: Due to dietary fat? Roughly one in 10 U.S. women will eventually develop breast cancer. Moreover, the incidence of the disease has risen steadily in women over age 44 -- by almost 2 percent a year since 1960, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. a new study. Trends uncovered in this and another analysis suggest that fatty diets may help drive the increase.

He was also the compere of Network Ten's game show The Con Test. . Glass at the Kaiser Permanente Kaiser Permanente is an integrated managed care organization, based in Oakland, California, founded in 1945 by industrialist Henry J. Kaiser and physician Sidney R. Garfield. (KP) Center for Health Research in Portland, Ore., and Robert N. Hoover, an epidemiologist with the National Cancer Institute (NCI See Liberate. ) in Bethesda, Md., focused on 1,765 Portland women on the KP health plan who were diagnosed with invasive breast cancer between 1960 and 1985. Over the 25-year period, breast cancer incidence rose from an average of 69.2 cases per 100,000 women to 100.3 -- but only among women age 45 and older, the researchers report in the April 18 JOURNAL OF THE NATIONAL CANCER INSTITUTE. Rates also varied dramatically for the two major types of breast malignancies -- those with receptors for the hormone estrogen and those without. Between 1974 (when KP began regularly assaying estrogen-receptor status) and 1985, the incidence of estrogen-negative breast cancers rose 27 percent, while that of estrogen-positive cancers increased 131 percent. Increases for both types occurred mainly in women over age 60. Several previous studies have indicated rising breast cancer rates in several countries, but this is the first to suggest the increase occurs primarily in estrogen-positive malignancies, says NCI medical oncologist medical oncologist Oncology An oncologist who diagnoses and treats cancer with chemotherapy, hormones, biologicals, or immunologic agents; the MO becomes a cancer Pt's de facto primary care giver, and coordinates treatment provided by other specialists. F. Andrew Dorr. Because obesity can elevate circulating estrogen levels in older women, potentially making them more prone to estronge-positive breast cancers, the new data imply that "dietary fat reduction may be important in decreasing the risk of breast cancer," Dorr says. Geoffrey R. Howe of the National Cancer Institute of Canada concurs that "there is a real possibility" the Portland cancer increase relates to diet. In the April 4 JOURNAL OF THE NATIONAL CANCER INSTITUTE, the Toronto epidemiologist and his colleagues review data from 12 studies of diet and breast cancer. They say their analysis suggests that if all North American North American named after North America. North American blastomycosis see North American blastomycosis.
