Missiemoo1959,
Your husband should have had a bone scan (to see if any prostate cancer has spread to the bones) and a multi-parametric MRI (mpMRI) scan to look at prostate itself, and the area around it such as lymph nodes.
Other things can raise PSA, such as prostate infection or urinary tract infection (UTI), so a high PSA doesn't necessarily mean prostate cancer, but it must be checked for.
You should be called back for an appointment to tell you the results of the mpMRI and bone scan, and then to go through what further diagnosis needs doing, if anything. If this hasn't happened, contact the urology department and ask.
