Moreover, the risk of breast cancer appears higher for women having their first birth at an older age and with a family history and it is not reduced by breastfeeding. The process of obtaining informed consent for all fertility treatments, therefore, must make patients aware of the facts that every pregnancy, to a small degree, will increase the short-term breast cancer risk. This observation may be even more relevant in cases of surrogacy where women agree to conceive without deriving benefits of offspring from assuming the risk, thus creating a substantially different risk-benefit ratio. Consequently, it appears prudent for professional societies in the field to update recommendations regarding consent information for all fertility treatments but especially for treatments involving surrogacy.<\/jats:p>","DOI":"10.1093\/humrep\/deaa102","type":"journal-article","created":{"date-parts":[[2020,5,27]],"date-time":"2020-05-27T11:27:50Z","timestamp":1590578870000},"page":"1253-1255","source":"Crossref","is-referenced-by-count":3,"title":["Transiently
