Study shows protective cells reduce lung cancer risk in ex-smokers

A new study could explain how lung cancer risk is reduced by quitting smoking. Published in the journal Nature in January 2020, the study shows that ex-smokers have a greater number of lung cells that have healthy genes compared to current smokers. Healthy genes are less likely to transform into cancerous cells.

			Protein p38 plays key role in supporting lung cancer growth In 2018, 1.7 million people died from lung cancer worldwide, a number equivalent to the population of Barcelona. The high mortality rate of lung cancer reflects the need for the development of treatments that are more efficient.

			Potential New Metabolic Biomarkers of Lung Cancer Identified with Magnetic Resonance Spectroscopy Researchers have successfully identified metabolic biomarkers able to determine between the different major subtypes of lung cancer.

	Interleukin-1-beta-induced chronic inflammation promotes lung cancer metastasis The study reveals a detailed epigenetic mechanism for how interleukin-1-beta, a common cytokine that helps fight infections during inflammation, plays a critical role in cancer metastasis.

	Analysis shows overall survival in lung cancer patients harboring 'niche' mutations Mutations were observed in all genes studied, except c-MET, DDR2, MAP2K1, and RET.

	Study uncovers higher lung cancer rates in young women across multiple countries An International Journal of Cancer study that examined lung cancer rates in young adults in 40 countries across five continents uncovered a trend of higher lung cancer rates in women compared with men in recent years.

	New therapeutic strategy for lung cancer and associated secondary tumors In 20 - 40% of patients with cancer, metastasis (the development of secondary tumors) in the central nervous system (CNS) occurs. CNS metastatis impacts negatively on a patient's quality of life, and is associated with a poor health prognosis.
