We read with interest the letter from Ponti et al. Rising breast cancer incidence rates in Turin between 1992 and 1999 seem, like our 1980's data (1), to reflect the influence of initial screening mammography. Individual-level data from populations with substantial exposure to menopausal hormone therapy and established screening programs, such as Kaiser Permanente Northwest and others (2), may be necessary to fully understand the combined effects of these factors on breast cancer incidence.
