My Ovarian Cancer is stable but not shrinking — is treatment still working

Understanding Stable Disease in Ovarian Cancer

This is an excellent and important question. The short answer is: yes, stable disease can represent meaningful progress, though your oncologist needs to evaluate your specific situation to determine if your current treatment should continue.

What "Stable Disease" Actually Means

When doctors say your cancer is "stable," they mean the tumors are not growing and not shrinking — they're staying roughly the same size on imaging scans. This is different from:

• Progressive disease (tumors growing)
• Partial response (tumors shrinking by 30% or more)
• Complete response (no visible cancer remaining)

Why Stable Disease Matters in Ovarian Cancer

According to current medical thinking, stable disease represents a real clinical benefit, even though it might not feel like "success" compared to shrinking tumors. Here's why:

The Clinical Reasoning:

• In ovarian cancer, preventing growth is a significant achievement — it means the treatment is controlling the cancer's ability to spread
• Stable disease buys time and maintains quality of life while your immune system and the medication work together
• For some patients, stable disease can last months or even years, which is meaningful survival benefit

As one cancer expert noted in discussing treatment response: "If I could get my disease to stop spreading, one day, I'll die of a heart attack or get hit by a bus. That seems like a pretty good option." This reflects the reality that halting cancer progression is a legitimate treatment goal.

Questions to Ask Your Oncology Team

Since your situation is unique, have this conversation with your doctor:

1. How long has the disease been stable? (Longer stability is generally more encouraging)

2. What are your tumor markers showing? (CA-125 levels can provide additional information beyond imaging)

3. Are there any signs of progression in other areas — lymph nodes, fluid accumulation, or other sites — even if the main tumors appear stable?

4. Should we continue the current treatment, or would you recommend adjusting it? (Stable disease sometimes warrants continuing the same approach, or sometimes switching strategies)

5. What would we look for as signs that the treatment needs to change? (Understanding the "trigger points" helps you stay informed)

6. How frequently should we scan to monitor this? (Some doctors increase monitoring frequency with stable disease to catch any changes early)

The Bigger Picture

Your oncologist will consider:

• How long you've been on current treatment
• Your side effects and quality of life
• Whether your tumor markers are stable or changing
• Your overall health and performance status
• Available treatment options if changes are needed

Important reminder: Stable disease doesn't mean "do nothing" — it means your current treatment is working to control the cancer, and your doctor will monitor closely for any changes that would warrant adjustment.
