[|Human|] hi...saw my urologist today..PSA has been erratic for a few years up and down. Today it was the highest it s been at 4.98. The digital exam was normal. Soft and smooth he said. We re going to retest in 6 weeks and he says no sex or masturbation 2 weeks before the blood test. Thoughts? How can we tell if it s BPH instead of cancer or is there no clear cut way unless you have a biopsy?
[|AI|]  PSA levels up to 4 is perfectly alright. BPH patients show up to 10 which is also ok. the PSA levels are only indicative of the prognosis and the extent of the disease but are never diagnostic and confirmatory. Malignant changes give a hard palpation on examination. But according to reports PSA levels greater than 40 are more likely to be Malignant. Biopsy are always diagnostic. If you are willing for an invasive procedure go for a biopsy.
