Pancreatic cancer can be difficult to detect in its early stages because its symptoms may be subtle or resemble common digestive problems. The pancreas is located deep within the abdomen, and early tumors may not cause noticeable symptoms.
Recognizing potential warning signs and discussing persistent or unexplained changes with a healthcare professional can help ensure that problems are investigated promptly.
Two Possible Early Warning Signs
1. Jaundice
One of the important warning signs of pancreatic cancer is jaundice, a condition in which the skin or whites of the eyes become yellow.
Jaundice can occur when a tumor blocks the bile duct, preventing bile from flowing normally. Other possible signs include dark urine, pale-colored stools, and itching.
Jaundice has many possible causes, including gallstones, liver disease, and other conditions. However, unexplained jaundice should be medically evaluated promptly.
2. Unexplained Weight Loss
Unexpected weight loss can occur with pancreatic cancer and other serious illnesses. A person may lose weight because of reduced appetite, digestive problems, changes in metabolism, or difficulty digesting and absorbing nutrients.
Losing weight without intentionally changing your diet or activity level should not automatically be attributed to stress or aging. Persistent or significant unexplained weight loss deserves medical evaluation.
Other Symptoms to Watch For
Pancreatic cancer can cause a range of symptoms, although these symptoms are also common with many less serious conditions.
Possible symptoms include:
- Persistent abdominal or upper-back pain
- Loss of appetite
- Nausea or digestive discomfort
- Changes in bowel movements
- Fatigue
- New or worsening diabetes
- Jaundice
- Unexplained weight loss
The location and severity of symptoms can vary from person to person.
Why Early Detection Can Be Difficult
The pancreas is located deep inside the abdomen, and pancreatic cancer may not produce obvious symptoms during its early stages. As a result, some people are diagnosed only after the disease has progressed.
There is also no routine screening test recommended for pancreatic cancer for people at average risk. People with certain inherited genetic conditions or a strong family history may have a higher risk and may benefit from discussing specialized screening with a healthcare professional.
When Should You See a Doctor?
Do not panic if you experience one of these symptoms. Most symptoms associated with pancreatic cancer can have many other causes.
However, you should speak with a healthcare professional if you develop persistent or unexplained symptoms, particularly unexplained weight loss, jaundice, ongoing abdominal or back pain, or significant changes in digestion.
Unexplained jaundice should receive prompt medical attention.
The Bottom Line
Pancreatic cancer can be challenging to identify early because its symptoms are sometimes vague. Unexplained jaundice and unexpected weight loss are two important warning signs, but neither symptom means that a person necessarily has pancreatic cancer.
Pay attention to persistent changes in your health and seek appropriate medical evaluation rather than trying to diagnose the cause yourself. Early medical assessment can help identify the underlying problem and determine whether further testing is necessary.
