Pancreatic cancer is a malignant tumour that develops in the tissues of the pancreas, an organ sitting deep behind the stomach responsible for digestion and insulin production. It’s hard to detect early because the pancreas has no nerve endings that register pain until disease has already spread, early symptoms like indigestion, mild back pain, and fatigue are indistinguishable from common conditions, and standard imaging misses small tumours routinely.
According to Dr. Vipulroy Rathod, an experienced Gastroenterologist in Mumbai, “Pancreatic cancer is one of the few cancers where the biology itself works against early detection by the time the patient feels something is wrong, the disease has usually already progressed beyond where surgery is straightforward.”
What Is Pancreatic Cancer and How Does It Develop?
Not a single disease, pancreatic cancer includes different cell types, can arise in different parts of the pancreas, and behaves differently, making it essential to understand the specific type when planning treatment decisions
- Exocrine Tumours, the Most Common: Around 95% of pancreatic cancers are exocrine, specifically pancreatic ductal adenocarcinoma aggressive, fast-growing, and typically found at advanced stage because it produces no distinct early symptoms until it obstructs something.
- Endocrine Tumours, Rarer but Different: Pancreatic neuroendocrine tumours develop from hormone-producing cells, grow more slowly than exocrine types, and actually carry a better prognosis when caught before metastasis a completely different clinical picture from PDAC.
- How It Spreads: Pancreatic cancer invades local blood vessels and nerves early, spreads to liver and lungs, and does this quietly because the pancreas sits in a location where pressure and obstruction symptoms only appear after significant local spread has already happened.
- What Triggers It: Chronic pancreatitis, smoking, diabetes, obesity, BRCA2 mutations, and a family history of pancreatic cancer are the main established risk factors, though a meaningful number of cases show up in patients with none of these.
Early diagnosis changes everything here. A specialist in pancreatic cancer treatment will know exactly which investigation pathway applies to your specific presentation.
Why Is Pancreatic Cancer So Difficult to Detect Early?
Several reasons, and they compound each other in a way that makes this particular cancer uniquely difficult to catch.
- Location Is the Core Problem: Pancreas sits deep in the retroperitoneum, surrounded by other organs, no direct access without imaging and that means a tumour can grow to a significant size before causing any physical obstruction or pain that brings a patient in.
- Symptoms That Fool Everyone: Early pancreatic cancer produces nausea, vague upper abdominal discomfort, fatigue, mild back pain none of which is specific, all of which get attributed to gastritis, muscle strain, or stress for months before anyone investigates further.
- CT Misses Small Tumours: Standard CT scans regularly miss pancreatic lesions under 2cm and those are exactly the ones where surgical resection is still possible and outcomes are meaningfully better so the investigation tool most GPs order first is also the one most likely to miss what matters.
- No Routine Screening Exists: Unlike colorectal or cervical cancer there’s no population-level screening programme for pancreatic cancer in India, so high-risk patients with family history or chronic pancreatitis aren’t being systematically monitored unless they’re with a specialist who knows to watch them.
But early detection is possible with the right approach. Read more on endoscopic procedures without surgery to understand how minimally invasive investigation works in practice.
Why Choose Dr. Vipulroy Rathod
Dr. Vipulroy Rathod has been working in gastroenterology and EUS since 1998 over 30 years building diagnostic accuracy in exactly the cases where standard investigations stop finding things. Trained physicians from 35 countries. Manages pancreatic cancer from initial suspicion through staging and intervention at Fortis Hospital Mulund. Patients arrive with vague symptoms, normal CT reports, months of no answers. Most leave with a real finding and a clear next step. That’s not luck. That’s 30 years of knowing where to look.

Frequently Asked Questions
Unexplained weight loss, mild upper abdominal pain, new onset diabetes, and jaundice are the most recognised early signals.
CA 19-9 is a tumour marker used alongside imaging but is not specific enough for standalone early detection.
Early-stage surgical resection gives a 5-year survival rate of around 20 to 30%, significantly better than late-stage diagnosis.
People with BRCA2 mutations, chronic pancreatitis, or two or more first-degree relatives with pancreatic cancer should be on active surveillance.
