Lung cancer

Introduction

Summary

Lung cancer is the most common cancer type and the most common cause of cancer death in the world. In 2022 almost 2.5 million people were diagnosed with lung cancer and more than 1.8 million people died from the disease. Lung cancer causes more than twice as many deaths as colorectal cancer, which is the second most common cause of cancer death. The enormous burden of lung cancer obscures the fact that most cases are avoidable. The principal risk factor for developing lung cancer remains tobacco smoking, which is responsible for approximately 85% of all cases. Other common causes include exposure to contaminants such as second-hand tobacco smoke, outdoor and indoor air pollution, diesel engine exhaust, welding fumes, and asbestos.
