Cancer of the Pancreas




Overview, Causes, & Risk Factors

Pancreatic cancer occurs when cells within the pancreas undergo changes that make the cells grow and divide uncontrollably.
What is going on in the body?
The pancreas is a gland located in the middle part of the upper abdomen. Insulin is produced by the pancreas to help the body regulate blood glucose. The pancreas also produces substances to help the body digest food. When a cell in the pancreas becomes cancerous, it grows into a tumor that destroys the tissue around it.
A tumor in the pancreas tends to quickly invade the nearby liver. Eventually, the liver will be affected, and part of it will be destroyed. The cancer can also metastasize, or spread, through the bloodstream to other parts of the body. Pancreatic cancer is usually found late in the disease when it is most likely to be fatal.
What are the causes and risks of the disease?
Cigarette smoking significantly increases a person's risk for pancreatic cancer. It is not clear if other factors also increase the risk. The influence of alcohol and caffeine on the development of this cancer is uncertain and controversial

 

Symptoms & Signs

What are the signs and symptoms of the disease?
Most people do not realize they have pancreatic cancer until it has advanced into the liver. At that time, the person will have symptoms related to the destruction of the liver. Unexplained weight loss is the most common symptom. Other symptoms may include:

  • jaundice, or yellowing of the skin and eyes
  • nausea and vomiting
  •  pain in the middle to upper part of the abdomen that may spread to the back              



    • Diagnosis & Tests

    How is the disease diagnosed?
    Diagnosis of pancreatic cancer begins with a medical history and physical exam. The healthcare provider may order tests, including:

  • an abdominal CT scan
  • a biopsy to remove a small piece of tissue for examination
  • CT scans and specialized X-rays to determine if the cancer has spread



    • Prevention & Expectations 

    What can be done to prevent the disease?
    Individuals who smoke can lower their risk for pancreatic cancer if they quit smoking. Some studies suggest that people who have had a tonsillectomy or various allergies may be at less risk for pancreatic cancer, but more research is needed.
    What are the long-term effects of the disease?
    If found early, the cancer can sometimes be controlled for a period of time. However, pancreatic cancer usually causes death. The average survival is 4.1 months.
    What are the risks to others?
    Pancreatic cancer is not contagious and poses no risk to others.

    Sputum Cytology

    How is the test performed? This test is usually performed in the morning, right after waking up. The person is asked to rinse his or her mouth with water to avoid a poor sample. After taking several deep breaths, the person then coughs deeply. This should bring up enough of a material from deep in the lungs known as sputum. Sputum is different from spit. The sputum sample is then taken to a lab. The lab can then examine the sample with a microscope    What is involved in preparation for the test? Instructions on sample collection are provided to people having this test. No other special preparation is needed   What do the test results mean? Usually, sputum contains some normal cells. No cells that look like cancer should be in the sample. If cancer cells are seen, the person usually has lung cancer.

    Toxic Shock Syndrome

    Introduction Toxic shock syndrome, or TSS, is a rare, potentially life-threatening disorder. It occurs when toxins made by certain types of bacteria are released into the bloodstream. What is going on in the body? Toxic shock syndrome was first described in children in 1978. Experts quickly realized it happened more often among women who used superabsorbent tampons during their periods. TSS is triggered by toxins made by Staphylococcus aureus bacteria. The toxins cause a high fever and can damage the kidneys, liver, and heart. Experts believe that tampons may block bacteria within the vagina. The moist, humid environment allows them to grow and produce high levels of toxins. Tampons can cause very small cuts in the vagina during insertion. These small cuts allow bacteria and their toxins to enter the bloodstream. About 70% of TSS cases have been related to certain brands of highly absorbent tampons that are no longer made. What are the causes and risks of the...

    Bone Marrow Biopsy

    Who is a candidate for the procedure? A person may undergo a bone marrow biopsy in order to: diagnose different types of leukemia when a blood test shows suspicious cell changes follow the response to a leukemia treatment help in diagnosis and treatment of certain other cancers diagnose and monitor the treatment of certain noncancerous blood disorders How is the procedure performed? First, the skin over the rear of the pelvic bone is cleansed. Local anesthesia is used to numb the area. Sometimes a drug is given intravenously to help calm the person having the procedure. A hollow stainless steel needle is inserted into the back part of the pelvic bone. Once it is inside the bone, a sample of the liquid marrow is drawn into the syringe. Sometimes a larger hollow needle is used to obtain a solid core specimen of marrow from the same area. No incision or sutures are needed. The sample taken is checked under a microscope for abnormal cells.     ...
