Abstract

Lung cancer has the highest prevalence in cancer-related deaths due to its rapid progression and it is detected at advanced stages. The paper proposes a novel method for predicting the risk of being malignant of Pulmonary Nodule (PN), presence of which can be an indication of lung cancer, with the motive to reduce the number of unnecessary biopsies and prevent anxiety among the patients. The study has considered different morphological features along with the clinical history of the patient having the particular nodule as described in medical literature. Depending upon these features, we have classified the risk of being malignant of pulmonary nodule into two classes, namely, low-risked or benign and high-risked or malignant. The entire dataset required to design the model is collected from a retrospective dataset, containing 476 (401 Malignant or high-risked and 75 low-risked or benign) PNs. The classification is performed by Recursive Partitioning Algorithm (RPA). RPA not only improves the accuracy but also helps to interpret how the morphological features are classifying the true risk of being malignant of the nodules.
