Proportional area of the tumour components determined by deep neural network (DNN) digital pathology in 140 rectal cancers. In most tumours, epithelium forms the major part and epithelial cells predominate. Desmoplastic stroma forms a significant part of most tumours while inflamed stroma makes up a smaller, variable proportion. Few tumours are mucinous. Non‐neoplastic tissue and necrosis form only a minor part in most annotated tumour regions. [Colour figure can be viewed at wileyonlinelibrary.com]
