Doctors urge assessment of persistent cough and other possible lung cancer signs
Doctors in India say a persistent or worsening cough needs medical assessment, though it does not necessarily mean lung cancer.
The condition can be hard to detect early because its symptoms may resemble common breathing problems.
Other possible warning signs include coughing up blood, breathlessness, chest pain, fatigue and unexplained weight loss.
People with a smoking history, exposure to second-hand smoke, previous cancer or a family history may need evaluation, but lung cancer can also affect people who have never smoked.
A clinical assessment can help identify whether symptoms are caused by lung cancer or another condition, such as asthma, COPD, tuberculosis or interstitial lung disease.
Finding lung cancer early can make surgery an option, with the operation depending on the tumour’s size, location and spread.
The doctors advise seeking medical advice about concerning symptoms.
Doctors say a cough that lasts for weeks, worsens or does not respond to usual treatment should be assessed because it can be an early sign of lung cancer.
Other possible warning signs include coughing up blood, breathlessness, chest pain, unexplained weight loss, loss of appetite and fatigue.
These symptoms can also occur with other lung conditions, making clinical assessment important to identify the cause.
People with smoking history, second-hand smoke exposure, previous cancer or a family history of lung cancer may need evaluation, but lung cancer can also affect people who have never smoked.
Doctors say early detection can improve treatment options, including surgery in some cases.

What people are saying
A persistent cough is often treated as an infection, an allergy, or a minor irritation of the airways.
However, when a persistent cough lasts for weeks, does not improve with usual treatment or gets worse gradually, it should not be ignored, as it can be an early warning sign of lung cancer
However, lung cancer can also appear in people who have never smoked.
The operation involves removing the tumour while preserving as much lung function as possible,
