A PSA of four is in the normal range.

Before doing a biopsy an MRI should be done. That will show if there’s anything in the prostate that looks like it might be cancer. If the doctor is not doing an MRI, you need to find another doctor. The MRI allows them to do a directed biopsy, if they find anything, otherwise they are shooting in the dark.

It sounds like your husband had BPH. There’s no reason that would be a cause to say you have cancer when the PSA goes back down so much.

You might want to look for a center of excellence to get treatment that is using the latest technology. If you say what area you live in, we can give you some help on that.
