Pancreatic Cancer (Head of Pancreas)
What is Pancreatic Cancer (Head of Pancreas)?
Pancreatic cancer of the head develops in the front section of the pancreas, the organ that produces digestive enzymes and regulates blood sugar. The head of the pancreas sits near the bile duct, which carries digestive fluid from the liver to the small intestine. When tumors grow in this location, they often press on the bile duct and block the normal flow of bile.
This type of cancer accounts for about 60 to 70 percent of all pancreatic cancers. The compression of the bile duct can cause an early warning sign called jaundice, which is yellowing of the skin and eyes. This happens when bilirubin, a yellow pigment from broken-down red blood cells, cannot drain properly and builds up in the blood and urine.
Pancreatic cancer is serious and often diagnosed late. However, tumors in the head of the pancreas may show signs earlier than those in other parts of the organ because of the bile duct obstruction. Early detection through routine testing and attention to symptoms can make a meaningful difference in treatment outcomes.
Symptoms
- Yellowing of the skin and whites of the eyes, known as jaundice
- Dark urine that looks tea-colored or brown
- Light-colored or greasy stools that float
- Itchy skin without visible rash
- Pain in the upper abdomen that may spread to the back
- Loss of appetite and unintended weight loss
- Nausea and vomiting
- New-onset diabetes or worsening blood sugar control
- Fatigue and weakness
- Digestive problems and feeling full quickly
Many people have no symptoms in the very early stages. Jaundice is often the first noticeable sign because tumors in the pancreatic head block the bile duct relatively early. If you notice yellowing of your skin or eyes, or dark urine, contact a healthcare provider right away.

Causes and risk factors
The exact cause of pancreatic cancer is not fully understood. It happens when cells in the pancreas develop DNA changes that cause them to grow out of control. These abnormal cells form a tumor that can invade nearby tissues and spread to other parts of the body. Several risk factors increase the likelihood of developing this cancer, including smoking tobacco, which doubles the risk. Chronic inflammation of the pancreas, diabetes, obesity, and a family history of pancreatic cancer also raise risk.
Age is a significant factor, with most cases occurring in people over 65. Other risk factors include heavy alcohol use, exposure to certain chemicals in metalworking and dry cleaning, and inherited genetic syndromes like BRCA2 mutations. People with chronic pancreatitis or long-standing diabetes should monitor their pancreatic health closely. Making lifestyle changes like quitting smoking, maintaining a healthy weight, and eating a diet rich in vegetables and fruits may help reduce risk.
How it's diagnosed
Diagnosis of pancreatic cancer starts with noticing symptoms and getting the right tests. Urine testing can detect elevated bilirubin levels, which appear when bile duct blockage causes this pigment to spill into urine. Dark urine is often one of the first signs that prompts further investigation. Rite Aid offers testing that includes urine bilirubin, which can identify this early warning sign during routine screening.
If elevated bilirubin is found or symptoms appear, doctors typically order imaging tests like CT scans, MRIs, or ultrasounds to look at the pancreas and bile ducts. Blood tests may check for tumor markers like CA 19-9, though this is not specific to pancreatic cancer. A biopsy, where a small tissue sample is removed, confirms the diagnosis. Early detection through routine testing and attention to symptoms is critical for better treatment options.
Treatment options
- Surgery to remove the tumor if caught early, often called the Whipple procedure
- Chemotherapy to destroy cancer cells and slow tumor growth
- Radiation therapy to target cancer cells and shrink tumors
- Targeted therapy drugs that attack specific cancer cell characteristics
- Immunotherapy to help the immune system recognize and fight cancer
- Pain management through medications and nerve blocks
- Nutritional support with enzyme supplements to aid digestion
- Stent placement to relieve bile duct blockage and reduce jaundice
- Eating small, frequent meals high in protein and calories
- Working with a specialist oncology team for coordinated care

Frequently asked questions
Tumors in the head of the pancreas sit right next to the common bile duct. This location means they often block bile flow early, causing jaundice and dark urine. These symptoms can appear sooner than with tumors in other pancreatic locations. This early warning sign may lead to earlier diagnosis and treatment.
Urine testing can detect elevated bilirubin, which appears when a tumor blocks the bile duct. Dark urine is often an early warning sign that something is wrong. While urine bilirubin alone does not diagnose cancer, it signals the need for further testing. Catching this sign early can lead to faster diagnosis and better outcomes.
When a tumor grows in the head of the pancreas, it presses on the bile duct. This blocks the normal flow of bile from the liver to the intestines. Bilirubin, a yellow pigment in bile, builds up in the blood and tissues instead. This causes the yellowing of skin and eyes known as jaundice.
Most cases of pancreatic cancer are not inherited, but about 10 percent have a genetic link. Having a close relative with pancreatic cancer increases your risk. Inherited gene mutations like BRCA2, PALB2, and Lynch syndrome also raise risk. If you have a family history, talk to your doctor about genetic counseling and screening.
Dark urine combined with jaundice, pale stools, or upper abdominal pain can signal bile duct blockage. This may be caused by a tumor in the pancreatic head or other conditions affecting the bile ducts. It is important to see a healthcare provider quickly for testing. Early evaluation can identify the cause and guide treatment.
Yes, certain lifestyle changes can lower your risk. Quitting smoking is the most important step, as smoking doubles pancreatic cancer risk. Maintaining a healthy weight, limiting alcohol, and eating a diet rich in vegetables and fruits also help. Managing diabetes and avoiding exposure to industrial chemicals further reduce risk.
Survival depends on how early the cancer is found and whether it can be surgically removed. Tumors caught early before spreading have better outcomes, with five-year survival rates around 20 to 40 percent after surgery. Unfortunately, many cases are diagnosed late, which lowers survival rates. Early detection through symptom awareness and testing is critical.
When surgery is not an option, treatment focuses on controlling cancer growth and managing symptoms. Chemotherapy and radiation can shrink tumors and slow progression. Stents may be placed to open blocked bile ducts and relieve jaundice. Pain management, nutritional support, and palliative care improve quality of life.
New-onset diabetes in adults over 50 can sometimes be an early sign of pancreatic cancer. If you develop diabetes suddenly or your blood sugar becomes harder to control, mention this to your doctor. They may recommend additional testing, especially if you have other risk factors. Routine monitoring of metabolic markers is important for early detection.
Contact a healthcare provider immediately if you notice jaundice, dark urine, pale stools, or unexplained weight loss. Early evaluation with blood and urine tests can identify warning signs. Imaging studies and specialist referrals may follow. Quick action improves the chances of finding cancer early when treatment is most effective.
