Should I get screened for a persistent cough and chest pain?

Question

Hello doctor,

I smoked heavily for almost 25 years and quit four years ago, but I have had persistent chest pain on the left side and a cough that has not gone away for ten weeks, despite taking two courses of antibiotics. My father died of lung cancer at the age of 63, and I am genuinely worried. However, my general practitioner keeps saying it is probably post-infectious inflammation and has not referred me for any scans. I am a former smoker with chest pain.

Should I get screened for lung cancer?
What type of scan is most appropriate for someone with my history?
At what point should these symptoms in a former smoker be urgently investigated rather than just monitored and reassured?

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand why this situation is worrying, especially considering the history of heavy smoking and the family history of lung cancer. When symptoms such as a persistent cough and chest discomfort continue for several weeks, it is reasonable to seek a clearer medical evaluation.

A cough that lasts for about ten weeks in a former smoker should not simply be ignored. In many cases, the cause may still be something less serious, such as post-infectious airway inflammation, chronic bronchitis, or gastroesophageal reflux disease (GERD). However, when symptoms persist despite treatment, it is usually appropriate to perform further investigations rather than relying only on reassurance.

For individuals with a similar background, the first step most doctors recommend is chest imaging. In many situations, a computed tomography (CT) scan of the chest is the most informative test because it provides a detailed view of the lungs and surrounding structures.

A CT scan can detect smaller abnormalities that may not be visible on a chest X-ray (CXR). This test is commonly considered when a persistent cough or chest pain does not improve after several weeks, especially in individuals with a past smoking history.

Certain symptoms usually require more urgent investigation rather than simple monitoring. These include:

A cough lasting for several weeks without improvement.
Coughing up blood (hemoptysis).
Unexplained weight loss.
Persistent chest pain.
Increasing shortness of breath (dyspnea).
Repeated chest infections.

In former smokers, the presence of these symptoms often justifies proper imaging to ensure that no serious underlying condition is overlooked.

In clinical practice, many patients with similar concerns undergo imaging studies. In many cases, the results show benign conditions, such as airway inflammation or scarring following an infection. However, performing appropriate imaging helps clarify the cause of symptoms and provides reassurance.

Because the cough has persisted for about ten weeks and has not improved after antibiotic treatment, discussing the possibility of a chest CT scan (computed tomography scan) with the treating physician would be a reasonable next step. If symptoms worsen or new symptoms develop, seeking prompt medical evaluation is recommended.
