Lung Radiation Therapy

Lung Tumor Treatments

Dr. Linson may use IMRT or SBRT to treat a lung tumor. The recommended approach depends on whether the tumor is primary or metastatic, its type, number, size and location, prior treatment, symptoms and the goals of care.

• IMRT (Intensity Modulated Radiation Therapy) shapes radiation from multiple directions to conform the dose to the treatment area while limiting exposure to nearby healthy tissue.
• SBRT (Stereotactic Body Radiation Therapy) delivers highly focused radiation in a small number of treatments and may be considered for selected targets.

How We Keep Your Treatment Accurate

• 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

• The radiation therapists will carefully position you in the same way as during simulation.
• Imaging confirms your position before each treatment is delivered.
• 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

• Short-term side effects often improve within 4–6 weeks, although recovery varies.
• Continue routine care with your primary care clinician and other members of your cancer-care team.
