Most significantly, the margins from the specimen shouldn't be compromised by acquiring samples for research with the surgical margins. In the same way, measurements with the thickness with the pigmented as well as other neoplastic lesions should not be compromised. So, for little lesions, a single could possibly be limited to obtaining smaller samples absent form the margins but towards the edge of lesions. This should not be a difficult or time consuming procedure.
On the list of significant challenges in evaluating prostatic adenocarcinoma (PCa) Bright field imaging is the fact that PCa usually can not be distinguished very easily from benign prostatic tissues on gross evaluation. Also, PCa easily infiltrates benign prostatic tissue and adjacent tissues (e.g., seminal vesicles). So, it is tough making sure that sections taken to reveal PCa in fact incorporate tumor.
