What is stereotactic radiosurgery (SRS) and how is it used for lung cancer?

SRS is a highly precise type of radiation therapy that uses many small beams of radiation aimed at a tumor from multiple angles. Despite the name "surgery," it's actually a non-invasive radiation treatment - no incisions are involved.

For lung cancer, SRS is sometimes used to treat metastases that have spread to the brain instead of whole-brain radiation. It's also part of a broader category called stereotactic body radiation therapy (SBRT), which can be used to treat early-stage lung cancer.

During treatment, you would lie on a table while a machine (like CyberKnife) delivers precise radiation to the tumor site for about 10 to 40 minutes. After the session, you can go home the same day.

Recent studies have shown that this type of targeted radiation can be just as effective as surgery for early-stage non-small cell lung cancer, with potentially easier recovery and better quality of life. It's particularly helpful for people who may not be good candidates for traditional surgery.

Your cancer doctor can help determine if SRS is right for your specific situation and explain the potential benefits and drawbacks compared to other treatment options.
