Yes, it's completely reasonable for your doctor to order another bone marrow biopsy even if you had one just 3 months ago. Rising IgG levels and an abnormal free light chain ratio can be signs that myeloma activity is changing, and your care team needs the most current picture of what's happening in your bone marrow. Doctors use several tools together to monitor myeloma, including:
- Blood and urine tests to track M protein, IgG levels, and light chain ratios
- Bone marrow biopsy to directly check for myeloma cell activity
- Imaging scans like PET or CT to look for changes in bones or other areas
A biopsy taken 3 months ago may not reflect what's happening now, especially if your numbers are trending upward. Your doctor may be checking whether this signals a relapse or a need to adjust your treatment plan. It's worth having an open conversation with your specialist about what they're looking for and what the results might mean for next steps. You're absolutely right to stay on top of these changes — catching a shift early gives more options.
