摘要

Advancements of diagnosis and treatment have substantially improved cancer survival rates in the last few decades.

We performed a MEDLINE search from 1971 to 201! in a similar way as Jensen et al. 2011, using the following MeSH terms: antineoplastic agents; ovarian failure; premature; infertility, female; fertility preservation; child and cancer; reproductive technologies, assisted.
