Pancreatic cancer occurs in the pancreas, a large gland behind the stomach that produces enzymes & hormones that help digest food & regulate blood sugar levels.

 Pancreatic cancer occurs when abnormal cells in the pancreas begin to grow uncontrollably & form a tumor.

Over time, these cancerous cells can spread (metastasize) to other parts of the body, such as the liver, lungs, & abdominal cavity.

There are two main types of pancreatic cancer: exocrine tumors & endocrine tumors. 

Exocrine tumors are the most common type & develop in the cells that produce enzymes to help digest food. 

Endocrine tumors, also known as pancreatic neuroendocrine tumors (PNETs), develop in the cells that produce hormones such as insulin & glucagon, which regulate blood sugar levels.

The exact cause of pancreatic cancer is unknown, but certain risk factors may increase a person's likelihood of developing the disease. 

These include smoking, obesity, chronic pancreatitis (inflammation of the pancreas), a family history of pancreatic cancer, and certain genetic conditions such as Lynch syndrome & BRCA mutations.
