External-beam radiation and what to expect.
Patient Guide
Lung Radiation Therapy
Radiation therapy may be used alone or with chemotherapy to treat lung cancer. Targeted high-energy x-rays are aimed at the tumor, and sometimes nearby lymph nodes, while the plan limits radiation to surrounding healthy tissue.

- A customized support such as a Vac-Lok cushion helps reproduce your position.
- CT simulation maps the tumor and nearby organs.
- The physician defines the target and organs to protect; the dosimetrist and medical physicist create and verify the plan.
- Image guidance confirms tumor location and positioning before radiation is delivered.
Before the First Treatment
- Complete your consultation.
- Complete CT simulation and individualized treatment planning.
- The care team completes dose calculations and quality checks.
During Treatment
- Fatigue or reduced energy is common. Balance activity with rest and tell the team if fatigue interferes with daily life.
- If the esophagus is in the treatment area, swallowing discomfort or a lump-in-the-throat feeling may begin after several treatments.
- A dry cough may develop. Report a worsening cough, changing mucus or any blood when coughing.
- Ask before using over-the-counter medicines for treatment-related symptoms.
After Treatment
Treatment effects may begin about two weeks after radiation starts and continue throughout treatment. They usually improve gradually after treatment is completed, although recovery time varies from person to person.
