Radiation for non-small cell lung cancer

External beam treatment directs radiation from a machine toward the tumour while you lie still. Imaging helps the team map the tumour and protect nearby tissue such as the heart, oesophagus and healthy lung. Stereotactic body radiotherapy may be considered for a small, clearly defined tumour when very precise treatment is suitable.

Radiation may be the main local treatment, combined with drug treatment, given before or after surgery, or used to shrink cancer that is causing pain, bleeding, cough, breathlessness or pressure. Common effects can include tiredness, skin irritation, cough, or discomfort when swallowing; the area treated and the dose influence what you notice.

Your oncology team will review scans, breathing, previous treatment and medicines before planning. Tell them about implanted devices, pregnancy or possible pregnancy, and any trouble swallowing or breathing. Attend planning and treatment visits as arranged, keep fluids available if allowed, and ask which activities should be adjusted. Report new symptoms early so they can be assessed and treated.

Your plan may include surgery such as lung lobectomy or medicines such as immunotherapy or targeted therapy. These choices depend on tumour features and overall health, so ask how the treatments fit together rather than comparing them in isolation.

Contact your cancer team promptly for worsening breathlessness, a new or increasing cough, fever, chest pain, repeated vomiting, or difficulty swallowing fluids. Seek emergency help for severe breathing difficulty, blue lips, sudden confusion, or coughing up a large amount of blood.

Ask where the radiation will be aimed, what it is intended to achieve, how many visits are expected, and which nearby organs need protection. Ask how treatment may affect breathing, swallowing and energy, what symptoms should be reported the same day, and whether surgery or medicines will be combined with radiation.
