No direct cause has been related to this disease but some risk factors have been reported: endocrine, genetic, diet and lifestyle factors. The main goal of this work was to identify a possible relationship between birth control pill administration and the occurrence of malignant/benign mammary tumours in clinical diagnosed females. Pet owners of bitches and queens diagnosed with mammary tumours were inquired on specie, age, tumour diagnosis date, natural or contraception birth control, contraception active drug ingredient, tumour origin (benign or malignant) and their awareness on pills contraindications.porCanineFelineMammary tumorsBirth-control pillconference poster
