Understanding Your IPMN Growth
Thank you for sharing this important detail. An IPMN (Intraductal Papillary Mucinous Neoplasm) that's growing is something that requires careful monitoring and discussion with your care team. Let me help you understand what this means and what typically comes next.
What Your Growth Means
A 3mm increase over 11 months is measurable growth, which changes how your IPMN should be managed. IPMNs are precancerous lesions (abnormal growths with potential to become cancer), and growth rate is one of the key factors your doctors use to decide on next steps.
Recommended Next Steps
According to the NCCN Guidelines for Pancreatic Adenocarcinoma, the management of IPMNs depends on several factors:
Key considerations your team should evaluate:
- Size and location of the IPMN (main duct vs. branch duct)
- Growth rate (which you now have data on)
- Imaging features (appearance on CT or MRI)
- Presence of symptoms
- Your overall health and surgical candidacy
Typical Management Options
Based on American Cancer Society and NCCN Guidelines, growing IPMNs typically warrant:
- More frequent imaging - Shorter surveillance intervals (possibly every 3-6 months instead of annually)
- Advanced imaging - MRI/MRCP (specialized pancreas imaging) if not recently done
- Specialist consultation - Consider seeing a pancreatic surgeon if you haven't recently
- Possible endoscopic ultrasound (EUS) - A procedure that gets detailed images and can obtain tissue samples if needed
Important Questions to Ask Your Doctor
- Is this a main duct or branch duct IPMN?
- What do they recommend for surveillance frequency going forward?
- Are there any concerning features on imaging that suggest higher risk?
- Would they recommend surgical evaluation given the growth?
This is a conversation to have with your pancreatic oncologist or surgeon soon. The growth you've documented is important information that should guide your next steps.
