The persistent cough: when can it be a warning sign and when to see a doctor

El Periódico Mediterráneo - General11 September 2026 at 10:25

Chronic cough is not always a symptom of another disease and may require specific treatment. It is one of the most common consultations in Pneumology, although it can generate concern due to its possible relationship with lung cancer.

Specialists recall that less than 2% of people who consult for chronic cough finally receive this lung cancer diagnosis. Although persistent cough can be alarming for many patients, the probability that it is associated with cancer is very low.

The article addresses the question of when a cough that doesn't go away should worry us and when we should go to the doctor for an adequate assessment.

In summary, chronic cough is a very common reason for consultation that in most cases is not related to serious diseases, but that may require medical attention and specific treatment depending on the case.
