Prolonging the age at which women become pregnant is linked to an elevated risk of developing cancer, including salivary gland tumours (SGT). However, awareness of this correlation remains limited. The aim of this study was to analyse the incidence and therapeutic options for SGTs during pregnancy on the basis of multicenter retrospective cohort analysis. The database of 2653 patients with SGTs from major centers in Poland included 1313 women, 300 were aged 16-42 years. 6 patients with SGTs during pregnancy were identified (w malignant, 4 benign). One case of sudden tumour occurrence and doubling of its mass suggested a malignant transformation. A standard diagnostic protocol is recommended during pregnancy with surveillance for benign and surgical resection for malignant SGT, regardless of the pregnancy stage. The risk of malignant transformation of SGT during pregnancy implies the need for resection before planned conception.
