Plain-English summary

A female dog with mammary tumors, which make up about half of all tumors in female dogs, was discussed in relation to how hormones affect their growth. The role of spaying (ovariohysterectomy) as a treatment option is still debated among veterinarians. Some believe that spaying after a tumor diagnosis might influence the tumor's growth and spread. This review looks at the hormonal factors involved in these tumors and the potential benefits of spaying when done alongside tumor removal surgery.

Abstract

As neoplasias mamarias constituem aproximadamente 50% dos tumores diagnosticados em cadelas. Apesar dosharmónios sexuais femininos desempenharem papel fundamental no desenvolvimento desses tumores em mamíferos, o valor da supressão hormonal pela ovário-histerectomia como auxiliar no tratamento do tumor de mama em caninos permanece controverso. Discute-se ainda se a realização da ovário-histerectomia após o diagnóstico influencia ou não o crescimento e progressão do tumor na glândula afetada ou em outras glândulas mamarias. O objetivo desta revisão é discutir alguns aspectos relacionados à influência hormonal na etiologia de tumores mamarias em cadelas, assim como o valor terapêutico da castração, quando realizada no momento da mastectomia.<br>The mammary neoplasms comprises aproximatel 50% ofthe diagnosed tumor s m the bitch.
