Cancer Incidence in Women After Medically Assisted Reproduction

In this cohort study of cancer incidence in women who received MAR, the overall incidence of cancer was comparable with that of the general population. The incidence of certain cancers appeared elevated; however, the excess numbers of these cancers were small, and there was reduced incidence of other cancers. Causation cannot be inferred from this descriptive evidence, but findings may guide women and their health care practitioners.
