Understanding Pancreatic Cancer
To grasp the severity of pancreatic cancer, it’s essential to understand what it is and how it affects the body. Pancreatic cancer originates in 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. There are several types of pancreatic cancer, with pancreatic ductal adenocarcinoma being the most common, accounting for about 90% of cases.
The Role of the Pancreas in the Body
The pancreas is a vital organ located behind the stomach, playing a key role in digestion and glucose regulation. It produces digestive enzymes that help break down food into smaller molecules that can be absorbed by the body, and hormones like insulin that regulate blood sugar levels.
Prevalence and Mortality Rates in the United States
Pancreatic cancer is relatively rare but highly lethal. According to the American Cancer Society, in 2023, there were an estimated 64,050 new cases of pancreatic cancer diagnosed in the United States, and about 50,550 deaths from the disease.
| Year | New Cases | Deaths | 5-Year Survival Rate |
|---|---|---|---|
| 2020 | 57,600 | 47,050 | 10% |
| 2021 | 60,430 | 48,220 | 10% |
| 2022 | 62,210 | 49,830 | 11% |
