@shep247 Welcom to MCC. You are going to read a lot of informatino and get confusing. Really learn to asked questions of your R/O and urlogist. Then do research and second opinions.
A PSA score of 4 is right at normal. Anything above 4 is abnormal. It does nto mean cancer but if it continues to rise most likely is. Just remember that almost every man will get prostrate cancer if they lived long enough. Most are very slow growing but need treatment or monitoring.
What ever your decisions please consider getting second opinions, PSMA test (will show if cancer has spread), bone scan (will show if in bones) and most important Decipher test (it will show a more precise risk level of your prostrate cancer). If and when you have biopsie ensure, if possible, it is MRI/Fusion and done by an experience urologist surgeon.
A patient who has research, second opinions, best diagnosis test, is in a better position to decide what treatments are best for them. Remember we are all different, with different cancers, and what is best for one is not necessarily best for you.
Thank you for the feedback and the details on the biopsy type! I will be looking into that, and, yes, I am definitely assembling a growing list of questions.
