Canine mammary cancer tumour behaviour and patient survival time are associated with collagen fibre characteristics

Abstract Precise diagnosis and prognosis are key in prevention and reduction of morbidity and mortality in all types of cancers. Here we show that changes in the collagen fibres in the main histological subtypes of canine mammary gland carcinomas are directly associated with the tumour behaviour and...
