Smoking is not always the cause of lung cancer, according to a report published by the German medical outlet Medical Tribune on Wednesday. The publication's headline states plainly that cigarettes are not responsible in every case, pointing to causes of the disease that sit outside tobacco use.
Coverage aggregated alongside the Medical Tribune item, attributed to Vietnam.vn, describes lung cancer risks that receive less attention than smoking. One of those reports is framed as a health news update dated 14 September. The same outlet also published material on proactive screening and what it calls the "golden time window" for treating respiratory disease.
A further Vietnam.vn item quotes Associate Professor Tran Van Ngoc as saying lung cancer can also appear in teenagers. Another piece from the outlet examines Vietnam's medical heritage in cancer treatment.
Taken together, the reports draw attention to patients who develop the disease without a smoking history, and to the role of early detection. The Vietnamese coverage places screening at the centre of its message, while the Medical Tribune headline addresses the question of cause.
Medical Tribune does not, in the material available, specify which non-tobacco factors it is referring to, and no figures or study details were provided in the summary.
What to watch next: whether Medical Tribune publishes the underlying data behind its claim, and how Vietnamese health authorities respond to the screening push.
