Lung cancer remains highly lethal, with 1.8 million deaths in 2022 worldwide. Deaths exceed those from colorectal cancer by about 900,000. Although lung cancer is strongly linked to tobacco smoking, many people who never smoked still develop the disease, with roughly 30% of cases in Asia. A substantial share of never-smokers with lung cancer are women, prompting ideas that lung cancer in women may differ from other forms. Early detection through routine scans can improve outcomes, but eligibility rules often exclude young people and non-smokers, leading to late diagnoses. New mutation-targeted drugs can slow tumor growth and disrupt blood vessel formation, and research into neuron-like features of lung cancer cells may improve treatments for brain metastases.
"New drugs that target specific cancer-causing mutations are proving impressively effective. One drug approved in 2025, for example, slows tumour growth and stops the mass forming blood vessels that it needs to sustain itself. Researchers are also refining their understanding of how certain lung cancer cells resemble neurons - an insight that could lead to better therapies for lung cancers that spread to the brain."
