Lung cancer

Lung cancer begins when abnormal cells grow uncontrollably in lung tissue. The two broad groups are non-small cell lung cancer and small cell lung cancer. The exact type, stage, molecular findings, general health and the patient’s preferences guide clinical decisions.

A cough that does not settle, coughing blood, chest pain, breathlessness, hoarseness, repeated chest infections, unexplained weight loss or unusual fatigue should be assessed. These symptoms can have non-cancer causes, but persistent or worsening changes need medical review.

Tobacco smoke is the leading avoidable risk. Radon, occupational exposure to asbestos or certain chemicals, air pollution, previous chest radiation and family history can also affect risk. A risk factor does not mean a person will develop cancer.

Assessment may include examination, chest imaging and tissue sampling. Pathology confirms the type. Biomarker or molecular tests may help identify targeted treatment options. PET/CT, brain imaging or other tests may be used for staging when clinically appropriate.

Depending on type and stage, a multidisciplinary team may discuss surgery, radiotherapy, chemotherapy, immunotherapy, targeted therapy or symptom-focused care. Some early cancers can be treated locally; advanced disease often needs systemic treatment. Only the treating oncology team can recommend a plan.

Not smoking and avoiding second-hand smoke reduce risk. Eligible high-risk adults should ask a qualified clinician whether low-dose CT screening is appropriate; screening criteria vary by country and individual history.

What is the exact pathology and stage? Were molecular tests completed? What is the goal of treatment? Which benefits, side effects and alternatives apply to me? Do I need urgent treatment, and which records should be reviewed before travel?
