Summary

This study looks at two ways of giving focused radiation (radiosurgery) to people with brain metastases that are 4 cm or smaller. One method uses a 0mm margin around the tumor, the other uses a 2mm margin. The goal is to find out which approach better controls the tumor while causing fewer side effects. About 180 adults aged 19 and older will take part.
