Cancer and pregnancy: what should we know about the management with systemic treatment of pregnant women with cancer?

The incidence of cancer during pregnancy is a rare phenomenon and is estimated to occur in 1:1000 pregnancies. This co-existence is likely to rise since the delay of childbearing to the later reproductive age is nowadays more common in families. The most frequent malignancies diagnosed during pregnancy are breast cancer, cervical cancer, haematological malignancies (lymphomas and acute leukaemias) and melanoma. Less common tumours are gastrointestinal, urological and lung cancers [1].
