Early Stage Squamous Cell Lung Cancer Detection

Abstract

Smoking and consuming alcohol leads to dangerous disease Squamous cell Lung Cancer (SqCLC). It is widespread all over the world today. The mortality rate of this cancer is on the higher side as it is diagnosed in stage III or IV. Small nodules are formed in the lungs in the starting stage, and gradually spreads in and around lung regions by a process of metastasis. Only few symptoms are seen in early stages of Cancer. Diagnosing Lung Cancer in the early stage is essential. The paper attempts to diagnose Lung Cancer in early stages by processing the Chest Computed Tomography (CT) image and segment the small lung nodules. The method uses the median filter to filter the noise and Watershed transform in combination with Morphology-based region of interest segmentation to fragment the nodules. Various metrics of the nodules in the image are calculated and the stage of Lung Cancer is determined.
