Early diagnosis of pancreatic cancer is difficult, and it may be challenging to detect through annual physical exams. This is because the pancreas is located in a hidden position, making early tumors difficult to detect through routine physical examinations. Additionally, tumor marker tests related to pancreatic cancer may not show elevated levels in the early stages.

Pancreatic cancer is a highly malignant tumor of the digestive system with a very high mortality rate. Due to the hidden location of the pancreas, early tumors are difficult to detect through routine physical examinations.

Even with annual physical exams, early detection of pancreatic cancer can still be missed. This is because the pancreas is located behind the peritoneum, obstructed anteriorly by organs such as the stomach and colon, making smaller pancreatic tumors difficult to detect through routine physical examinations, including abdominal palpation and ultrasound scans.

Additionally, commonly used tumor marker tests, such as CA19-9 and CEA, may not be elevated in early-stage pancreatic cancer, which can lead to missed diagnoses during health checkups.

If symptoms suggestive of pancreatic cancer arise, such as abdominal pain, jaundice, or significant weight loss, it is important to seek prompt medical attention and undergo more detailed examinations to improve the early diagnosis rate.
