Breast Cancer Screening by Physical Examination: Randomized Trial in the Phillipines
Abstract
In 1990 breast cancer accounted for 795,000 new cases per year (Ferlay et al,1998), and it was the most frequent cancer in women. Incidence rates are still rising in many countries, particularly in the developing world (Coleman and Esteve, 1993). It seems that these trends are likely to continue, since the current pattern of later childbearing, decreasing fertility, and westernization' of diets will all be associated with increased risk. At present, our knowledge of environmental risk factors does not permit formulation of any practical primary prevention programs. The introduction of adjuvant therapy with Tamoxifen has improved survival of older cases and a decline of mortality from breast cancer below age 50, observed in some high-risk countries, has also been attributed to adjuvant therapy (Nab et al.,!., 1994, Olivotto et al., 1994). However, further improvements in surgical techniques, or in radiotherapy, are very unlikely to provide more than marginal changes in mortality rates.
