I was diagnosed with PDAC at age 39 after almost 8 months of issues. Even though neuroendocrine tends to be a slower and less aggressive form of pancreatic cancer, I would absolutely push for more testing and not wait 3 months. Perhaps after they discuss her case with the tumor board, they will agree and proceed with testing. If not, I would seek second opinion or push for confirmative testing. She must advocate strongly for herself. I have learned that the hard way.
