My Prostate Cancer tumor markers are rising — what does this mean

Understanding Rising Prostate Cancer Tumor Markers

Rising tumor markers in prostate cancer can feel concerning, but understanding what they mean and what your care team should do next is important. Let me walk you through this.

What Rising Markers Generally Mean

When tumor markers like PSA (prostate-specific antigen) are rising, this typically suggests that cancer cells are becoming more active or increasing in number. However—and this is crucial—a rising marker by itself doesn't tell the complete story about what's happening with your cancer.

According to NCCN Guidelines for Advanced-Stage Prostate Cancer, rising PSA after treatment may indicate that the treatment is losing effectiveness. But the guidelines also emphasize that PSA alone can be misleading because:

• Age, infections, and other prostate conditions can raise PSA
• Some aggressive cancers produce less PSA than expected
• Treatment response isn't always reflected immediately in PSA numbers

The Importance of Looking Beyond PSA

This is where your oncologist's clinical judgment becomes essential. According to expert guidance from the CancerPatientLab webinars on prostate cancer, doctors should use multiple types of evidence to understand what rising markers mean:

Imaging scans are critical. As Dr. [removed] Antonarakis explains, "PSA is a rough marker. Scans and genetic tests should be performed to monitor therapeutic action. Sometimes PSA will increase but cancer scans show no growth or even regression."

Your care team may use:

• PSMA PET scans (a specialized scan that lights up prostate cancer cells)
• CT or bone scans to see if cancer is actually growing
• Blood tests to check other markers beyond PSA

What You Should Ask Your Oncologist

Since rising markers require personalized interpretation, here are specific questions to ask your care team:

1. "What is my PSA trend over time, and how fast is it rising?" (A slow rise may be different from a rapid spike)

2. "Do my recent scans show any new growth or changes, or do they look stable?" (This is often more important than PSA alone)

3. "Should we do any additional testing, such as genetic testing or liquid biopsies?" According to NCCN Guidelines, biomarker tests like circulating tumor DNA (ctDNA) can help monitor disease progression and may provide earlier detection of changes

4. "Are there any other markers we should be monitoring besides PSA?" (Your doctor may recommend tests like alkaline phosphatase or other blood markers)

5. "Does this change my current treatment plan, or should we wait for more information?"

Important Context

According to the CancerPatientLab webinar on Bipolar Androgen Therapy, even experienced oncologists sometimes need to be cautious about interpreting rising markers too quickly. As Dr. [removed] notes, "If PSA increases for 1-2 cycles, do not panic. PSA often increases before it starts going down."

The key is that your complete clinical picture matters—your symptoms, scan results, how you're feeling, and the rate of change all factor into what rising markers actually mean for your specific situation.

Next Steps

Don't wait passively with rising markers. Schedule a discussion with your oncologist to:

• Review your complete test results together
• Understand the trend (not just the current number)
• Discuss whether additional testing would be helpful
• Clarify whether your treatment plan needs adjustment
