What should you know about SBRT radiation for lung cancer?

SBRT radiation for lung cancer focuses several radiation beams on a defined tumour while limiting exposure to nearby healthy tissue. It may be considered for a localised lung cancer when the tumour's size, position, lung function and overall health make precise radiation suitable. The plan also depends on staging, tumour biology, previous treatment and whether surgery or another treatment offers a better fit.

Planning scans show the tumour as it moves with breathing and map nearby organs. During treatment, image guidance and a controlled breathing method may help position the target. A machine delivers radiation from multiple directions; the beams meet at the planned tumour. SBRT is a precise form of [Radiotherapy](/treatments/radiation-oncology/radiotherapy/), not an operation. It may be compared with [Lung Lobectomy](/treatments/surgical-oncology/lung-lobectomy/) or other approaches after the team reviews your scans and lung reserve.

You may have tiredness, cough, chest-wall soreness or shortness of breath. Radiation-related inflammation can appear later, so scheduled reviews remain useful even when treatment visits have finished. New symptoms should be assessed rather than self-diagnosed.

Ask whether tissue diagnosis, staging scans or [Genomic Tumour Profiling](/treatments/diagnostics-and-staging/genomic-tumour-profiling/) will change the plan. Give the team a complete medicine list and mention oxygen, lung disease, previous chest radiation, implanted devices and blood thinners. Clarify whether you need to hold your breath, change medicines or arrange transport. Depending on the stage and tumour features, the plan may include [Chemotherapy](/treatments/systemic-therapy/chemotherapy/), another local treatment or a symptom-focused approach such as [Palliative Care](/treatments/supportive-and-palliative-care/palliative-care/).

Contact your oncology team promptly for worsening cough, breathlessness, fever, chest pain, coughing blood, new confusion or a marked fall in usual activity. A hoarse voice can have several causes; discuss it with your team, especially if it persists or is joined by swallowing or breathing difficulty. Seek emergency help for severe breathing difficulty, blue lips, fainting, sudden weakness or significant bleeding.

Ask what stage and tumour features support SBRT, what alternatives apply, and how breathing motion and nearby organs will be managed. Ask what symptoms are expected, when scans will be reviewed, how genomic results could affect treatment, and who to contact at night or during a public holiday.
