Yes, as long as you understand that you won't know what you are dealing with by tomorrow - all you will know is whether your PSA is raised and whether you are to be referred to urologist for further assessment. As the GP has felt a hard area, I imagine you will be referred regardless of your PSA score but there is a long way to go ... probably including an MRI scan, biopsy, possible bone scan. Once all the results have been received, the urologist will assess all the information with colleagues from other disciplines and make a diagnosis. Strap in as it may be some weeks before you know exactly what is going on.
