Objective: The efficacy of treatment for many
cancers has increased dramatically in recent decades and there are a growing number of cancer survivors who need effective
contraception. In this paper, a group of experts from the European Society of
Contraception set out to define the most frequent
cancers in women and summarise the guidelines, reviews and studies that provide information and guidance on
contraception for each
cancer. Methods: Epidemiological studies were analysed to determine the frequency of
cancers in women of reproductive age. A narrative review was performed for each
cancer, collecting data about the treatment of the disease, its impact on fertility, and the efficacy, health risks, possible benefits and
contraindications of the
contraceptive methods available. The recommendations were then summarised. Results: Owing to a large amount of information, the results are presented in two parts. Part 1 includes
contraception after breast and gynaecological
cancers. Part 2 summarises the findings and recommendations regarding
contraception in women with skin, gastrointestinal, haematological and
endocrine cancers.
