What should you know about PSA 400 and prostate cancer?

Short answer
A PSA result of 400 needs prompt specialist assessment because it is markedly raised, but the result alone does not establish the diagnosis or extent of disease.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.

Why the result needs context
PSA can rise with prostate cancer, but infection, inflammation, urinary blockage, benign enlargement, and recent procedures can also affect it. A result this high warrants a clinician's prompt review, including questions about urinary symptoms, fever, pain, weight change, and previous results. It still cannot show by itself whether cancer is present, where it is, or how it may respond to treatment.
The assessment may include examination, repeat or additional blood tests, imaging, and biopsy where appropriate. Difficulty Passing Urine may reflect obstruction or irritation and should be reported, but it does not identify the cause of an elevated PSA.
Arrange coordinated care
Contact your doctor or oncology service promptly and take the laboratory report, prior results, medicine list, and details of any recent urinary infection or procedure. Ask how quickly examination and imaging should be arranged. If cancer is confirmed, specialists use biopsy and scans to guide a treatment plan rather than relying on PSA alone.
Possible treatments include Radiotherapy, Brachytherapy, Prostate Removal Surgery, or Targeted Radioisotope Therapy, depending on findings and health. Bone-Strengthening Therapy may be discussed when cancer affects bone or treatment creates bone-health concerns. Robotic Cancer Surgery is a surgical approach that may be suitable in selected cases, not a decision made from the PSA number alone.
When to seek urgent help
Seek emergency care for inability to pass urine, severe or new back pain, leg weakness or numbness, loss of bladder or bowel control, fever with shaking chills, confusion, or sudden severe illness. These symptoms can signal an urgent urinary, infectious, or nerve-related problem and should not wait for a routine appointment.
Questions for your doctor
Ask what could have contributed to the result, what tests are needed to confirm the cause, and whether imaging or biopsy is appropriate. Ask what symptoms require immediate help, who will coordinate your care, and how treatment choices would change if disease is found in or outside the prostate.
Questions people ask
Is PSA 400 proof of prostate cancer?
No. It is markedly raised and requires prompt assessment, but other prostate and urinary problems can affect PSA and diagnosis needs further testing.
What symptoms need urgent help with a very high PSA?
Inability to pass urine, severe back pain, new leg weakness or numbness, loss of bladder or bowel control, and fever with shaking chills need urgent care.
