For years, infertility specialists have insisted in scientific and
public arenas that a key IVF procedure known as ovarian
stimulation—chemically goosing women’s ovaries to ripen multiple eggs in
a single menstrual cycle—poses little or no long-term cancer risk for
those undergoing it.
Like so many other safety claims advanced by researchers and clinicians since the early days of reproductive medicine, this assertion has been made on the basis of virtually no solid evidence, and those who have accepted it can only have done so on the basis of faith: Over the last two decades, the two dozen or so scientific follow-up studies of women who have undergone ovarian stimulation have yielded conflicting results and have been largely unconvincing because they have looked at relatively small numbers of women, have collected a limited range of medical information, and have not tracked their subjects over a long period of time.
That said, a dozen or so previous studies pointed to an increased risk for both ovarian cancer and borderline ovarian tumors, malignancies that are usually self-contained and operable and have higher survival...
