I am not a medical professional.

My understanding is that the Whipple procedure is almost always combined with either adjuvant chemo/radiation (following the surgery), or neoadjuvant chemo/radiation before and after surgery.

Pancreatic cancer cells are very evasive and sneaky - they can remain in the surgical bed, be transferred via blood or contact with other organs, etc.

If you have not been evaluated by a center of excellence, please do. Also, you need to spend about 100 hours reading on this topic. Be your own advocate!
