How effective is stereotactic body radiotherapy for non-small cell lung cancer?

This treatment sends several precisely aimed radiation beams to a defined lung tumour while limiting exposure to nearby tissue. It is often considered for a small, localised tumour when surgery is not suitable, or when a focused treatment is needed for a particular site. The team reviews scans, breathing movement, tumour size and position, lung function, and whether cancer is present elsewhere. It may be used alone or alongside other treatments, depending on the whole cancer plan.

Planning usually includes detailed imaging, a body position that can be reproduced, and a method for accounting for breathing motion. Tell the radiation team about implanted devices, prior chest radiation, lung disease, oxygen use, and medicines. Ask whether you can eat normally, how to manage cough during planning, and when follow-up scans will assess the treated area. Fatigue, cough, or chest discomfort can occur after treatment and should be discussed.

Call the treatment team promptly for worsening breathlessness, chest pain, coughing blood, a persistent fever, or a cough that suddenly changes. Seek emergency help for severe breathing difficulty, blue lips, fainting, or sudden confusion.

Is my tumour suitable for focused radiation? What nearby organs affect the plan? Is surgery or another treatment also reasonable? How will scans distinguish treatment changes from active cancer?
