Understanding Pancreatic Cancer
Understanding pancreatic cancer requires a grasp of the pancreas’s role in the body. Pancreatic cancer is a serious condition that arises from the pancreas, an organ crucial for digestion and metabolism.
What is Pancreatic Cancer?
Pancreatic cancer occurs when abnormal cells in the pancreas grow and multiply uncontrollably, forming a tumor. This type of cancer is often diagnosed at a late stage, making it challenging to treat.
The Role of the Pancreas in the Body
The pancreas has two primary functions: producing digestive enzymes and regulating blood sugar levels through hormones.
Digestive Functions
The pancreas produces digestive enzymes that help break down food into smaller molecules that can be absorbed by the body. These enzymes play a crucial role in nutrient absorption and overall digestive health.
Hormonal Functions
The pancreas also produces hormones like insulin and glucagon, which regulate blood sugar levels. Insulin helps lower blood sugar by facilitating glucose uptake in cells, while glucagon raises blood sugar by stimulating the liver to release stored glucose.
