What is Pancreatic cancer?
What are the symptoms of Pancreatic cancer?
Pancreatic cancer is sometimes called a "silent disease" because early pancreatic cancer often does not cause symptoms. But, as the cancer grows, symptoms may include:
- Pain in the upper abdomen or upper back
- Yellow skin and eyes, and dark urine from jaundice
- Weakness
- Loss of appetite
- Nausea and vomiting
- Weight loss
These symptoms are not sure signs of pancreatic cancer. An infection or other problem could also cause these symptoms. Only a doctor can diagnose the cause of a person's symptoms. Anyone with these symptoms should see a doctor so that the doctor can treat any problem as early as possible.
Who is at risk for Pancreatic cancer?
No one knows the exact causes of pancreatic cancer. Doctors can seldom explain why one person gets pancreatic cancer and another does not. However, it is clear that this disease is not contagious. No one can "catch" cancer from another person.
Research has shown that people with certain risk factors are more likely than others to develop pancreatic cancer. A risk factor is anything that increases a person's chance of developing a disease.
Studies have found the following risk factors:
- Age -- The likelihood of developing pancreatic cancer increases with age. Most pancreatic cancers occur in people over the age of 60.
- Smoking -- Cigarette smokers are two or three times more likely than nonsmokers to develop pancreatic cancer.
- Diabetes -- Pancreatic cancer occurs more often in people who have diabetes than in people who do not.
- Being male -- More men than women are diagnosed with pancreatic cancer.
- Being African American -- African Americans are more likely than Asians, Hispanics, or whites to get pancreatic cancer.
- Family history-- The risk for developing pancreatic cancer triples if a person's mother, father, sister, or brother had the disease. Also, a family history of colon or ovarian cancer increases the risk of pancreatic cancer.
- Chronic pancreatitis -- Chronic pancreatitis is a painful condition of the pancreas. Some evidence suggests that chronic pancreatitis may increase the risk of pancreatic cancer.
Other studies suggest that exposure to certain chemicals in the workplace or a diet high in fat may increase the chance of getting pancreatic cancer.
Most people with known risk factors do not get pancreatic cancer. On the other hand, many who do get the disease have none of these factors. People who think they may be at risk for pancreatic cancer should discuss this concern with their doctor. The doctor may suggest ways to reduce the risk and can plan an appropriate schedule for checkups.
How to know you have Pancreatic cancer (Diagnosis)?
If a patient has symptoms that suggest pancreatic cancer, the doctor asks about the patient's medical history. The doctor may perform a number of procedures, including one or more of the following:
- Physical exam -- The doctor examines the skin and eyes for signs of jaundice. The doctor then feels the abdomen to check for changes in the area near the pancreas, liver, and gallbladder. The doctor also checks for ascites, an abnormal buildup of fluid in the abdomen.
- Lab tests -- The doctor may take blood, urine, and stool samples to check for bilirubin and other substances. Bilirubin is a substance that passes from the liver to the gallbladder to the intestine. If the common bile duct is blocked by a tumor, the bilirubin cannot pass through normally. Blockage may cause the level of bilirubin in the blood, stool, or urine to become very high. High bilirubin levels can result from cancer or from noncancerous conditions.
- CT scan (Computed tomography) -- An x-ray machine linked to a computer takes a series of detailed pictures. The x-ray machine is shaped like a donut with a large hole. The patient lies on a bed that passes through the hole. As the bed moves slowly through the hole, the machine takes many x-rays. The computer puts the x-rays together to create pictures of the pancreas and other organs and blood vessels in the abdomen.
- Ultrasonography -- The ultrasound device uses sound waves that cannot be heard by humans. The sound waves produce a pattern of echoes as they bounce off internal organs. The echoes create a picture of the pancreas and other organs inside the abdomen. The echoes from tumors are different from echoes made by healthy tissues.
The ultrasound procedure may use an external or internal device, or both types:
- Transabdominal ultrasound: To make images of the pancreas, the doctor places the ultrasound device on the abdomen and slowly moves it around.
- EUS (Endoscopic ultrasound): The doctor passes a thin, lighted tube (endoscope) through the patient's mouth and stomach, down into the first part of the small intestine. At the tip of the endoscope is an ultrasound device. The doctor slowly withdraws the endoscope from the intestine toward the stomach to make images of the pancreas and surrounding organs and tissues.
- ERCP (endoscopic retrograde cholangiopancreatography) -- The doctor passes an endoscope through the patient's mouth and stomach, down into the first part of the small intestine. The doctor slips a smaller tube (catheter) through the endoscope into the bile ducts and pancreatic ducts. After injecting dye through the catheter into the ducts, the doctor takes x-ray pictures. The x-rays can show whether the ducts are narrowed or blocked by a tumor or other condition.
- PTC (percutaneous transhepatic cholangiography) -- A dye is injected through a thin needle inserted through the skin into the liver. Unless there is a blockage, the dye should move freely through the bile ducts. The dye makes the bile ducts show up on x-ray pictures. From the pictures, the doctor can tell whether there is a blockage from a tumor or other condition.
- Biopsy -- In some cases, the doctor may remove tissue. A pathologist then uses a microscope to look for cancer cells in the tissue. The doctor may obtain tissue in several ways. One way is by inserting a needle into the pancreas to remove cells. This is called fine-needle aspiration. The doctor uses x-ray or ultrasound to guide the needle. Sometimes the doctor obtains a sample of tissue during EUS or ERCP. Another way is to open the abdomen during an operation.
