Congratulations to your son on the success of the treatment and the reduction in size of the NET. Seeking a second opinion is a good thing at this time, @kwan. If your son is not currently working with a NET specialist, I'd suggest that the second opinion be with a NET specialist.

You mentioned that your son had an unsuccessful Whipple procedure last April. Can you explain a bit about why it was unsuccessful? Was it the location or the size of the NET?
