What is Pancreatic cancer

Pancreatic cancer is a malignancy that begins in the tissues of the pancreas, a vital organ responsible for producing enzymes that aid digestion and hormones that regulate blood sugar. Because the pancreas is located deep within the abdomen, pancreatic cancer is often difficult to detect in its early stages, frequently requiring a multidisciplinary approach for diagnosis and management.

What is the pathophysiology of pancreatic cancer?

Pancreatic cancer occurs when cells within the pancreas develop genetic mutations that cause them to grow uncontrollably, forming a tumor. The majority (about 90%) of cases are pancreatic ductal adenocarcinoma, which originates in the cells lining the pancreatic ducts. This growth can obstruct the common bile duct, leading to jaundice, or interfere with the organ’s endocrine function, potentially triggering new-onset diabetes.

How is pancreatic cancer classified?

Clinicians generally categorize pancreatic cancer into two primary types based on the affected cells:

• Exocrine tumors: The most common form, including adenocarcinoma, which affects the exocrine glands responsible for digestive enzymes.


• Neuroendocrine tumors (pNETs): Rarer, slower-growing tumors that form in the hormone-producing cells (islets) of the pancreas.

Who is typically affected by pancreatic cancer?

Pancreatic cancer is most frequently diagnosed in individuals between the ages of 60 and 80. While the exact cause remains under study, identified risk factors include long-standing tobacco use, chronic pancreatitis, obesity, and certain inherited genetic syndromes. According to global health data, pancreatic cancer affects men slightly more often than women, and incidence rates vary by geographic region, often correlating with lifestyle factors and access to early screening.

How does pancreatic cancer differ from other digestive cancers?

Unlike many other gastrointestinal cancers, pancreatic cancer is characterized by a lack of early, specific symptoms, which often leads to a late-stage diagnosis. Furthermore, the tumor microenvironment in pancreatic cancer is notably dense and fibrous, which can act as a barrier to certain systemic therapies, making it a unique challenge for researchers and clinicians alike.
