This rare rash is strongly linked to glucagonoma—a rare pancreatic neuroendocrine tumor that overproduces the hormone glucagon. NME is often the first visible clue.
🧪 Dermatologists sometimes diagnose internal cancer based on this rash alone.
Action: If you have a migrating, painful rash that won’t heal, see a dermatologist—and request blood tests for glucagon levels.
💪 4. Unexplained Muscle Wasting & Weakness
What to notice:
Legs feel weaker, harder to climb stairs
Visible thinning of thigh or calf muscles
Fatigue that doesn’t improve with rest
Weight loss without trying
Why it matters:
Pancreatic cancer can trigger cancer cachexia—a metabolic syndrome that breaks down muscle and fat, even with adequate food intake. Legs often show wasting first due to gravity and use.
⚖️ This isn’t normal aging. It’s rapid, asymmetric, and paired with systemic decline.
Action: Track weight weekly. If you lose >5% of body weight in 6 months without dieting, seek medical evaluation.
