My wife of 47 years is currently fighting a re-occurance of malignant melanoma, which has metastasized to her brain. In order to combat it the Drs are going to try Brain Surgery. Thru all the discussion etc. they frequently referred to the procedure as SRS surgery. When we got home, wanting to know more about it, she Google d SRS, and was very amused to find that the only references to that she could find were to Sexual Reassignment Surgery, which she does not think she is a candidate for. She finally found it on a medical reference web site as Stereotaxic Radio-graphic Surgery.
