Problem
Rural areas lack access to CT screening, so lung cancer classification from widely available chest X-rays was needed.
Why it matters
Lung cancer is curable when diagnosed early, but CT access is limited in rural areas.
What the AI did
A 121-layer DenseNet-121 convolutional network with transfer learning, pre-trained on a lung nodule dataset, classified lung cancer from chest X-ray images.
Results
Mean accuracy 74.43±6.01%, specificity 74.96±9.85%, sensitivity 74.68±15.33%
Impact
Demonstrates feasibility of CNN-based lung cancer classification from chest X-rays at modest accuracy.

Early-stage lung cancer is curable and screening matters, but CT/LDCT access is very limited in rural areas; abstract gives no patient numbers; large-scale cancer screening problem inferred.
