Pancreatic Cancer (Head)
What is Pancreatic Cancer (Head)?
Pancreatic cancer of the head develops in the widest part of the pancreas. This section sits near the common bile duct, which carries bile from the liver to the small intestine. When tumors grow here, they often press against this duct and block the flow of bile.
This blockage causes jaundice, a yellowing of the skin and eyes. The blocked bile also raises bilirubin levels in your blood. Bilirubin is a yellow substance made when your body breaks down old red blood cells. Pancreatic head tumors are the most common type of pancreatic cancer, making up about 70% of all cases.
Early detection is difficult because symptoms often appear late. Many people feel fine until the tumor grows large enough to block the bile duct or spread. Blood tests that track bilirubin levels can catch these changes early, especially when tumors press on the bile duct.
Symptoms
- Painless yellowing of the skin and whites of the eyes, known as jaundice
- Dark urine that looks like tea or cola
- Pale or clay-colored stools
- Itchy skin all over the body
- Loss of appetite and unintended weight loss
- Pain in the upper abdomen that spreads to the back
- Nausea and vomiting
- New-onset diabetes or worsening blood sugar control
- Fatigue and weakness
- Swelling of the gallbladder that a doctor can sometimes feel
Many people have no symptoms in the earliest stages. Jaundice is often the first noticeable sign because head tumors block the bile duct early. This makes bilirubin testing valuable for catching potential problems.

Causes and risk factors
The exact cause of pancreatic cancer remains unclear. Cell mutations in the pancreas cause cells to grow out of control and form tumors. Risk factors include smoking, which doubles your risk. Chronic pancreatitis, a long-term inflammation of the pancreas, also raises risk. People with diabetes, especially new-onset diabetes in adults over 50, face higher rates. Family history matters, as 10% of cases run in families.
Other risk factors include obesity, heavy alcohol use, and exposure to certain chemicals. Age plays a role, with most cases occurring after age 65. People with certain genetic syndromes have higher risk. A diet high in red and processed meats may contribute. Most people with pancreatic cancer have no clear family history or genetic syndrome.
How it's diagnosed
Doctors diagnose pancreatic head cancer through multiple steps. Blood tests are often the first clue. Elevated bilirubin levels suggest a blocked bile duct, which can point to a tumor in the pancreatic head. Rite Aid offers bilirubin testing as part of our flagship panel with 200+ biomarkers. Progressive rises in bilirubin are a red flag that needs immediate follow-up.
After abnormal blood work, doctors order imaging tests. CT scans and MRI scans show the tumor and its size. Endoscopic ultrasound lets doctors see the pancreas closely and take tissue samples. A biopsy confirms cancer by examining cells under a microscope. Doctors also test tumor markers like CA 19-9, though these are less reliable for early detection than imaging and bilirubin levels.
Treatment options
- Surgery to remove the tumor, called a Whipple procedure, for localized cancers
- Chemotherapy drugs like gemcitabine or FOLFIRINOX to kill cancer cells
- Radiation therapy to shrink tumors or ease symptoms
- Stent placement to open blocked bile ducts and relieve jaundice
- Pain management with medications and nerve blocks
- Enzyme supplements to help digest food when the pancreas is damaged
- Nutritional support with high-calorie foods and supplements
- Clinical trials testing new treatments and drug combinations
- Palliative care to manage symptoms and improve quality of life
- Blood sugar monitoring and diabetes management if needed

Frequently asked questions
Pancreatic head cancer grows in the widest part of the pancreas near the bile duct. This location causes jaundice earlier than body or tail tumors because it blocks bile flow. Head tumors make up about 70% of all pancreatic cancers. Their earlier symptoms often lead to earlier detection compared to tumors in other areas.
Tumors in the pancreatic head press against the common bile duct. This blocks bile from flowing from the liver to the intestine. The trapped bile backs up into the bloodstream, raising bilirubin levels. High bilirubin causes the yellow color in skin and eyes known as jaundice.
Blood tests can catch early warning signs, especially elevated bilirubin from head tumors blocking the bile duct. Total bilirubin levels that keep rising are a red flag. Blood tests alone cannot diagnose cancer, but they prompt doctors to order imaging tests. Regular testing helps catch changes before symptoms appear.
Normal total bilirubin ranges from 0.1 to 1.2 mg/dL. Levels above 2.5 mg/dL usually cause visible jaundice. Progressive increases over time are more concerning than a single high reading. Your doctor will compare your results to your baseline and order imaging if levels climb steadily.
Pancreatic head cancer can be cured if caught very early and fully removed with surgery. About 20% of patients have operable tumors at diagnosis. Five-year survival rates are around 10% overall but reach 30% to 40% when surgery removes all visible cancer. Early detection through blood tests and imaging offers the best chance.
Overall five-year survival is about 10% for all stages combined. Localized cancer has a 39% five-year survival rate. Regional cancer that has spread nearby drops to 13%. Distant metastatic cancer has a 3% five-year survival rate. These rates improve when cancer is found early through screening blood work.
Anyone over 50 with new symptoms like jaundice, dark urine, or pale stools should get tested. People with risk factors including smoking, chronic pancreatitis, or family history benefit from regular screening. New-onset diabetes in older adults warrants bilirubin testing. Regular preventive testing helps catch problems before symptoms start.
Your doctor will first repeat the test to confirm the result. They will ask about symptoms like jaundice, itching, or abdominal pain. Imaging tests like ultrasound or CT scan show if something is blocking your bile duct. Depending on findings, you may need an endoscopy or biopsy to determine the cause.
Quitting smoking cuts your risk in half within 10 years. Maintaining a healthy weight through diet and exercise helps lower risk. Limiting alcohol and eating more vegetables and fruits may protect the pancreas. Managing diabetes and avoiding processed meats also contribute to prevention. These changes work best when started early.
Healthy adults should include bilirubin in annual preventive blood work. People with risk factors like chronic pancreatitis or family history may need testing every 6 months. If you have symptoms like jaundice, get tested immediately. Rite Aid members get tested twice yearly with our subscription, catching changes early.
