RT Journal A1 MacLennan AH, Baber R T1 HOrmone therapy use and risk of ovarian cancer JF JAMA JO JAMA YR 2009 FD November 25 VO 302 IS 20 SP 2203 OP 2204 DO 10.1001/jama.2009.1724 UL http://dx.doi.org/10.1001/jama.2009.1724 AB The most common presentation of asymptomatic ovarian cancer is the chance finding of a pelvic mass at manual or ultrasonic pelvic examination.2 Women using HT are likely to present for routine pelvic examination more often than nonusers of HT. The potential for such detection bias was not discussed in the article but could account for the small annual increase in ovarian cancer incidence of 1 in 8300.
