    "description": "Pancreatic cancer occupies an unusual position in the public mental model of cancer: most readers do not rank it among the most common killers by raw numbers (correctly — it is not), but most readers do file it as \"the bad one\", the diagnosis you do not want to hear. That intuition is approximately right. Pancreatic cancer kills fewer people each year than lung, colorectal, liver, stomach, or breast cancer, but it kills a much larger fraction of the people it diagnoses: five-year relative survival sits around 13% in the US and under 12% globally, the worst of any common solid tumor. The fear attached to the word \"pancreatic\" is a reasonably calibrated response to a genuinely grim case-fatality rate.\n",

Spread across a global adult population of ~5.5 billion (age 18+), ~467,000 pancreatic cancer deaths per year is ~0.85 per 10,000 adults per year. Naive 60-year compounding gives ~0.5%; age-weighting (pancreatic cancer mortality is heavily concentrated in the 60-80 band, with hazard several times higher in the last third of adult life than at the population average) pulls the realistic global adult lifetime figure up to roughly 0.8%. The direct US number from ACS is higher: lifetime risk of developing pancreatic cancer is ~1 in 56 for men and ~1 in 60 for women, and with 5-year relative survival of ~13% the implied long-run case-fatality is ~85-90%, giving a US lifetime pancreatic-cancer-death probability of ~1.4% (~1 in 71). Headline figure 0.008 (~1 in 125) with an uncertainty band of 0.005-0.015 to span the global-adult to US-adult range.

  "caveats": "Pancreatic cancer is the entry where the case-fatality rate, not the incidence, is the load-bearing number. Lifetime *incidence* in the US is ~1.6% per SEER — lower than breast, prostate, lung, or colorectal cancer by a wide margin. What makes pancreatic cancer distinctive is the compression between diagnosis and death: ~52,000 US deaths against ~67,000 US diagnoses in the same year gives a deaths-to-cases ratio approaching 0.8, the highest of any common cancer, and 5-year relative survival of 13% is the lowest in the SEER system for a solid tumor. The biology behind that compression is structural: the pancreas sits deep in the retroperitoneum behind the stomach, symptoms are vague and late, and only about 12-15% of tumors are caught at the localized stage where 5-year survival reaches 44%. There is currently no effective population-level screening program for average-risk adults — the USPSTF continues to recommend against routine screening — because the prevalence is too low and the available tests are not specific enough to avoid net harm. Surveillance imaging is only recommended for defined high-risk groups: hereditary pancreatitis, familial pancreatic cancer kindreds, and carriers of certain germline variants. The projected rise to the second leading cause of US cancer death by 2030 reflects improvements in treating the currently-larger cancers more than deteriorating pancreatic outcomes; age-standardized pancreatic cancer mortality has been roughly flat for decades.\n",
