Prostate Cancer-Detecting Dogs’ Olfactory Capacity Trains Neural Network for Combination Diagnostic Approach

Research by an international team of investigators has demonstrated the ability of trained dogs to detect aggressive prostate cancer from urine samples, and suggests that an artificial neural network could learn from this olfactory capability. The findings could feasibly be used to help direct the development of novel, machine-based tools for detecting prostate cancer, which integrate canine olfaction with the analysis of volatile organic compounds (VOCs) in urine, microbial profiling, and artificial neural network (ANN)-assisted examination.
