I was thinking of this when a friend passed away from pancreatic cancer a couple of weeks ago. One of the reasons pancreatic cancer is so deadly is that it is deeply internal and symptoms of it are not present. This is true with all of the deadliest cancers. We already recommend colonoscopy to older adults which is a fairly invasive procedure to screen for colon cancer with no other history. If we could scan people with low or no ionizing radiation that would be a great tool.
