Stereotactic Radiosurgery for Brain Metastasis
Stereotactic radiosurgery (SRS) is an option for one lesion up to a few lesions. This technique targets high doses of radiation precisely to the areas of cancer while minimizing any exposure to nearby healthy tissue — especially important when the brain is involved. This reduces the risk of side effects.
The areas of cancer would be mapped first using imaging scans so that the beams can be targeted precisely. You’re more likely to hear SRS described with brand names such as CyberKnife or GammaKnife, among others, but all of the machines work in a similar way. This technology is not available everywhere, so check with your doctor.
