Why is pancreatic cancer called the “king” of cancers?

While liver cancer is often dubbed the "silent killer," pancreatic cancer is considered the "king" among all cancers due to its extremely dangerous characteristics, even though it’s not the most common type. Here’s why:

  • Silent progression: In the early stages, pancreatic cancer rarely causes noticeable symptoms, so patients often don’t realize anything is wrong. By the time symptoms appear, the disease is usually already in advanced stages, metastasized, or inoperable.

  • Extremely low survival rate: According to the American Cancer Society, the 5-year survival rate for pancreatic cancer is only around 39% in stage 1, 13% in stage 2, and a mere 3% in stage 4 when the cancer has spread.

  • Difficult to treat and prone to metastasis: The pancreas is located deep in the abdomen, near vital organs like the liver, duodenum, and major blood vessels. This makes early detection and surgical removal extremely challenging. The tumor also tends to metastasize early to the liver, peritoneum, or lungs.

  • High recurrence rate: Even after complete removal, pancreatic tumors often recur.


5 Pancreatic Cancer Symptoms Commonly Mistaken for Digestive Issues

Patients with pancreatic cancer frequently experience digestive-related symptoms that are easily misdiagnosed as gastritis, peptic ulcers, indigestion, or acid reflux. Below are 5 common warning signs:


1. Upper abdominal pain radiating to the back
The most common symptom is a dull ache in the upper abdomen (epigastric area), often mistaken for a stomachache. However, pain from pancreatic cancer typically radiates to the back, especially when lying down or after eating. Some describe it as a squeezing sensation that only eases when leaning forward. Despite being a clear red flag, it's often overlooked due to its similarity to common gastric pain.

2. Persistent bloating, even after eating small amounts
As pancreatic function declines and enzyme production decreases, food digestion slows down, causing prolonged bloating or heaviness after meals—even small ones. This lasting indigestion is frequently mistaken for gastrointestinal disorders. A key clue is a persistent lack of appetite despite not feeling full, along with discomfort immediately after eating.


3. Rapid weight loss despite normal eating habits
The pancreas plays a vital role in digestion and blood sugar regulation. When affected by cancer, the body's ability to absorb nutrients is significantly impaired, leading to rapid weight loss without changes in diet or exercise. While weight loss is common in many cancers, it is especially pronounced in pancreatic cancer.


4. Nausea or vomiting after meals
A pancreatic tumor may compress the duodenum or block digestive flow, causing nausea or vomiting soon after eating—even after light meals. This symptom is often misattributed to acid reflux or food poisoning. However, it usually persists regardless of dietary changes.


5. Dark stools or vomiting blood
Pancreatic tumors can invade the duodenum, causing internal bleeding. This may result in black, foul-smelling stools, or in severe cases, vomiting blood. Unfortunately, most patients mistake this for a more common condition like stomach bleeding, leading to delayed or inadequate diagnosis and treatment.


Conclusion:
If you or someone you know experiences persistent digestive issues along with the symptoms above, it’s crucial not to dismiss them. Early medical evaluation can make a significant difference in outcomes when dealing with a cancer as aggressive as pancreatic cancer.
