On the other hand, SRS is a non-invasive procedure that delivers a single, high dose of radiation to a specific target in a single session. Unlike traditional surgery, which involves physically removing the tumor, SRS achieves tumor destruction through precise targeting of radiation beams. It’s commonly used for small to medium-sized tumors, especially those located in the brain, spine, and certain other areas where surgical intervention may be challenging.
Both SRT and SRS rely on advanced imaging techniques, such as MRI, CT scans, and/or PET scans, to precisely localize the tumor and guide the delivery of radiation with submillimeter accuracy. This precise targeting minimizes radiation exposure to surrounding healthy tissues, reducing the risk of side effects and improving treatment outcomes.
These treatment modalities offer several advantages over traditional radiation therapy and surgery. Firstly, they are less invasive, which means shorter recovery times and reduced risk of complications. Additionally, they can be used to treat tumors that may be considered inoperable or too risky for conventional surgery. Furthermore, SRT and SRS are highly effective in controlling or eliminating tumors, leading to improved long-term survival rates and quality of life for patients.
SRT and SRS have revolutionized the management of various cancers and other medical conditions, including brain tumors, spinal tumors, lung cancer, liver cancer, prostate cancer, and metastatic disease. They are often used as primary treatments, adjuvant therapies, or palliative measures, depending on the specific circumstances of each case.
