Pancreatic cancer is one of the deadliest cancers in the world, mainly because it’s very hard to catch early.
The pancreas is a small organ hidden deep in your belly, right behind the stomach. It plays two big roles—helping to digest food and keeping your blood sugar at healthy levels.
But if cancer starts in the pancreas, it usually grows without causing big problems at first. Many people don’t even know something is wrong until the cancer has already spread to other parts of their body. This late discovery makes it harder to treat and more dangerous.
One major reason why this cancer is so hard to find early is that the warning signs are small, unclear, and easy to confuse with other common problems. For example, a person might feel pain in their upper belly or in their back. This pain might come and go, and it doesn’t go away with rest or medicine.
Other early signs include losing weight without trying, feeling full very quickly even after eating just a little, or feeling sick in the stomach often. These symptoms are very easy to ignore. People might think it’s just stress or something they ate, so they don’t go to the doctor.
One sign that’s easier to notice is jaundice. Jaundice makes the skin and the whites of your eyes turn yellow. This happens when a tumor blocks the bile duct, which is a small tube that helps your body get rid of waste.
When this tube is blocked, a yellow substance called bilirubin builds up in the body. Along with yellow skin and eyes, you might see darker pee, lighter-colored or greasy poo, and feel itchy skin. These signs should never be ignored.
Losing weight without changing your diet or activity level can also be a sign. In some cases, this happens because the pancreas stops making enough enzymes to help digest food. Even if someone eats normally, their body may not absorb nutrients well, and that leads to weight loss.
A sudden case of diabetes—especially in people who never had blood sugar problems before—can also be an early clue. This is because the pancreas helps control insulin, the hormone that manages blood sugar. If a person develops diabetes without a clear reason, it’s a good idea to talk to a doctor and ask if more checks are needed.
Other general symptoms include feeling very tired, not wanting to eat, or just feeling unwell for no clear reason. These might not seem serious, but if they continue or come with other signs, they could be a warning.
There are also certain things that make a person more likely to get pancreatic cancer. People who smoke, are overweight, or have long-term inflammation in the pancreas (called pancreatitis) are at higher risk.
Your family history also matters. If a close family member had pancreatic cancer, your chances of getting it may be higher too. According to the American Cancer Society, smokers are about twice as likely to develop pancreatic cancer compared to non-smokers.
If you are at high risk and notice any unusual signs—especially yellow skin, stomach pain, or losing weight without trying—it’s very important to talk to your doctor. The earlier the cancer is found, the better the chances of treatment working well.
Doctors can use scans like CT scans or MRIs to check the pancreas. These tests can help find tumors or other problems early. Just because your doctor sends you for a scan doesn’t mean you have cancer, but it helps you find answers and take action early if needed.
In short, pancreatic cancer is dangerous because it usually starts quietly. But if you know the signs—like yellow skin, unexplained weight loss, belly or back pain, and new diabetes—you can take steps early.
Paying attention to small changes in your body could save your life. Don’t wait—if something feels wrong, talk to your doctor. It’s always better to be safe than sorry.
If you care about cancer, please read studies that a low-carb diet could increase overall cancer risk, and vitamin D supplements could strongly reduce cancer death.
