It has been suggested that early and late-onset breast cancer may actually be separate diseases with different aetiologies (DeWaard et al., 1964). The break observed in the age incidence curve around menopause (Clemmensen's hook) would coincide with the area where the curves for the two diseases overlap. The much more frequent late-onset breast cancer would(More)
The inconclusive findings of past analytic epidemiologic studies on diet and breast cancer may have resulted from the inability of these studies to assess early dietary exposures. The role of macronutrient intake during early life can be indirectly studied, however, by examining past and present body size. The authors identified by computer linkage a(More)
To further characterize the association of obesity and endometrial cancer, in particular with regard to the role of early-age obesity and adult weight gain, the authors assembled by computer linkage a population-based historical cohort of 30,266 women born between 1913 and 1932, for whom weight and height had been recorded in 1942-43 and 1972. Linkage of(More)
Orientals consisting of Japanese, Chinese, Koreans, and Filipinos are clearly at higher risk for cleft lip with or without cleft palate [CL(P)] than whites, Puerto Ricans, and Hawaiians/part-Hawaiians in Hawaii. Using the model of diallele cross, CL(P) incidences in incrosses and outcrosses involving 564,002 live births distributed among 669 mating types(More)
Wolfe's criteria were assigned to mammograms of 202 women without breast cancer. Parity decreased the frequency of P2 patterns but not DY. P1 and N1 patterns apparently increased at the expense of P2 patterns. For every birth, the probability that a P2 pattern changed to P1 or N1 was roughly 7 or 8%. This effect was not limited to the first pregnancy, but(More)
