A seemingly healthy 60-year-old man in Taiwan—a non-smoker, non-drinker with no discomfort—recently received a life-altering diagnosis: pancreatic cancer. The man had only noticed a 4 kg weight loss and slightly elevated blood sugar, which he attributed to successful dieting. Yet further testing revealed a tumour hidden deep in his abdomen. This case underscores a harsh reality: pancreatic cancer, ranked as Hong Kong’s fifth deadliest cancer, often strikes without warning.
The Unseen Danger
According to data from the Hospital Authority’s Hong Kong Cancer Registry, 946 new pancreatic cancer cases were recorded in 2019, with 530 in men and 416 in women—a male-to-female ratio of approximately 1.3:1. The pancreas sits deep within the abdominal cavity, making early detection notoriously difficult. Standard health checks rarely pick up the disease, and most patients are diagnosed only at an advanced stage. This earned pancreatic cancer the grim nickname “king of cancers.”
A Case Study in Denial
The Taiwanese man—aged 60, with no history of smoking or drinking—underwent a routine blood test during a health check. His Ca19-9 tumour marker level was 800 U/mL, more than 20 times the normal threshold. A CT scan then revealed a 2.5 cm tumour on his pancreas, highly suggestive of malignancy.
Despite the findings, the man refused surgery, insisting he felt fine. “Eighty percent of early-stage pancreatic cancer patients have no symptoms at all,” warned Dr. Lin Xiang-Hong, a gastroenterologist in Taiwan who shared the case. “Over half of those cases are discovered accidentally while checking for other conditions.”
Three months later, a follow-up scan showed the tumour had nearly doubled in size, from 2.5 cm to 3.6 cm. Dr. Lin urged immediate action: “Luck gave you a chance. If you keep avoiding treatment, the outlook will only worsen.”
Alarming Statistics: Survival Rates Drop Fast
The decision to delay treatment is particularly dangerous. Research shows that when a pancreatic tumour is smaller than 2 cm at the time of surgery, the five-year survival rate is about 50%. Once the tumour reaches between 2 cm and 4 cm, that rate plummets to just 15%. Even small tumours can metastasise early.
Recognizing the Red Flags
Many people dismiss unexplained weight loss combined with rising blood sugar as a sign of successful dieting. However, Dr. Lin notes that up to 80% of pancreatic cancer patients experience high blood sugar—a symptom that should never be ignored.
Other common signs include:
- Jaundice (yellowing of skin and eyes)
- Upper abdominal pain that radiates to the back
- New-onset diabetes without family history
- Pale, greasy stools
- Loss of appetite
- Unexplained fatigue
Who Is at Risk?
Risk factors for pancreatic cancer include both genetic and lifestyle elements:
- Family history of pancreatic or related cancers
- Chronic pancreatitis
- Smoking and heavy alcohol consumption
- Obesity and a diet high in processed meats
- Long-standing diabetes
- Age over 60
Even those without obvious risk factors—like the 60-year-old man—can still be vulnerable. Experts stress that no symptom is too small to investigate.
What You Can Do
While pancreatic cancer remains one of the most challenging cancers to treat, early detection saves lives. Regular health screenings—especially for those over 50 or with risk factors—should include blood tests for tumour markers and, if indicated, imaging like CT or MRI scans.
If you notice persistent weight loss, new-onset diabetes, or any digestive discomfort, consult a doctor immediately. Don’t assume you are simply “eating healthier.” The cancer’s silent progression means time is of the essence.
