Pancreatic cancer is a dangerous disease that starts in the pancreas, a small organ behind the lower part of your stomach. The pancreas helps with digestion and also keeps your blood sugar levels in balance.
One of the biggest problems with pancreatic cancer is that it’s often found too late. Many people don’t notice symptoms until the disease has already spread, which makes it harder to treat. That’s why it’s important to understand what causes pancreatic cancer and what research has found about ways to lower the risk.
Smoking is one of the top risk factors. Studies have shown that people who smoke are about twice as likely to get pancreatic cancer compared to those who don’t. That’s because the harmful chemicals in cigarette smoke can damage the DNA in the pancreas, which can lead to cancer. The good news is that quitting smoking can greatly reduce your risk.
Getting older is another factor. Most people who get pancreatic cancer are over 65. As we age, our cells can build up more damage, and that makes cancer more likely. While we can’t control our age, knowing this can help us be more alert to signs and get regular check-ups.
Family history and inherited genes also matter. If someone in your close family—like a parent or sibling—had pancreatic cancer, your chances of getting it are higher. Some people carry genetic changes that increase their risk. For example, changes in the BRCA1 or BRCA2 genes, which are also linked to breast cancer, can raise the risk for pancreatic cancer too.
Another important cause is chronic pancreatitis. This means the pancreas is inflamed for a long time. It can happen because of heavy alcohol use, gallstones, or inherited conditions. Chronic inflammation can damage cells in the pancreas and lead to cancer over time.
Being overweight or eating an unhealthy diet also raises your risk. People who are obese are more likely to get pancreatic cancer. Eating too much red meat, processed foods, or sugary drinks adds to the danger. On the other hand, staying at a healthy weight and eating more fruits, vegetables, and whole grains can help protect you.
Diabetes, especially type 2 diabetes, is another risk. Studies have found that people with diabetes have a higher chance of getting pancreatic cancer. It’s still not fully clear why, but high blood sugar and insulin problems may be involved. Taking care of your diabetes with good food, exercise, and medicine can help lower your risk.
Some jobs can also increase your risk. People who work with certain chemicals, like in metal factories or on farms with pesticides, might be more likely to get this cancer. Researchers are still studying this and looking for ways to keep workers safe.
Even though we can’t change things like age or family history, we can make choices to lower other risks. Not smoking, eating well, staying active, and keeping a healthy weight are all important. Also, knowing your family’s medical history and seeing your doctor regularly can help catch problems early.
Scientists are always working to learn more about pancreatic cancer. They’re trying to find better ways to detect it early and create treatments that work better. The more we understand about what causes this cancer, the more we can do to fight it.
Spreading awareness and learning the risks gives us the power to protect our health and support others. With continued research, there is hope that we’ll improve survival and help more people live longer, healthier lives.
