Is a high PSA suggestive of prostate cancer at 68?

Question

Hello doctor,

My uncle is 68 years old and recently had a routine health check in which his prostate-specific antigen (PSA) level was 8.4 ng/mL. He does not have major urinary symptoms but sometimes experiences a weak urine flow.

His doctor has advised magnetic resonance imaging (MRI) and a possible biopsy to confirm whether prostate cancer is present. We are concerned about the need for treatment if cancer is detected, especially considering his age and otherwise stable health.

How is prostate cancer usually managed, and does every detected cancer require immediate treatment?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I have gone through your query and understand your concern.

A PSA (prostate-specific antigen) of 8.4 ng/mL at age 68 is definitely something that needs proper evaluation, but it does not automatically mean prostate cancer is present. PSA can rise for several benign reasons as well, such as prostate enlargement, inflammation, or even recent urinary issues, which is why the MRI (magnetic resonance imaging) your doctor has recommended is the correct next step.

The MRI helps us identify whether there is a suspicious area in the prostate and whether a biopsy is actually needed, or where to target it if it is. This approach has really improved how we diagnose prostate cancer because it avoids unnecessary biopsies in many men.

If prostate cancer is found, not every case requires immediate treatment. Management depends mainly on how aggressive the cancer is, based on the biopsy (Gleason score), PSA level, MRI findings, and overall health.

Many prostate cancers are slow-growing and low-risk, and in those cases, we often use active surveillance, which means careful monitoring with PSA tests, repeat imaging, and sometimes repeat biopsies rather than immediate surgery or radiation.

For more intermediate- or high-risk cancers, especially if they are likely to grow or spread, active treatment such as surgery or radiotherapy is recommended. At 68, if he is otherwise healthy, he would generally be considered suitable for either option if needed.

The important reassurance is that prostate cancer is often very treatable, and even when it is present, there is usually time to make a considered decision rather than rushing into treatment.

The MRI and possible biopsy are simply to clarify whether there is anything significant that actually needs action.

I hope I have answered your question.
