Background: Lung cancer is the most common malignant neoplasm worldwide, accounting for greater mortality than due to any other cancer. It accounts for about 13% of all new cancer cases and 19% of cancerrelated deaths worldwide. In India, lung cancer comprises 6.9% of all new cases of cancer and 9.3% of all cancer-related mortality in both sexes. This study aimed to find out the socio-demographic characteristics of lung cancer patients in the North Malabar region of Kerala. Methods: This is a prospective observational analysis of 238 lung cancer patients in the North Malabar region of Kerala during the period of 2017 and 2018.
