Convolution Neural Networks for diagnosing colon and lung cancer histopathological images
This work addresses the need for automated diagnosis of specific cancer types, but it is incremental as it applies existing CNN methods to a new dataset without major methodological innovations.
The researchers tackled the problem of diagnosing lung and colon cancer from histopathological images by developing a computer-aided system using convolutional neural networks, achieving diagnostic accuracies of over 97% for lung cancer and over 96% for colon cancer.
Lung and Colon cancer are one of the leading causes of mortality and morbidity in adults. Histopathological diagnosis is one of the key components to discern cancer type. The aim of the present research is to propose a computer aided diagnosis system for diagnosing squamous cell carcinomas and adenocarcinomas of lung as well as adenocarcinomas of colon using convolutional neural networks by evaluating the digital pathology images for these cancers. Hereby, rendering artificial intelligence as useful technology in the near future. A total of 2500 digital images were acquired from LC25000 dataset containing 5000 images for each class. A shallow neural network architecture was used classify the histopathological slides into squamous cell carcinomas, adenocarcinomas and benign for the lung. Similar model was used to classify adenocarcinomas and benign for colon. The diagnostic accuracy of more than 97% and 96% was recorded for lung and colon respectively.
