Pancreatic Cancer

(Cancer of the Pancreas)

Definition

Pancreatic cancer is the growth of cancer cells in the pancreas. The pancreas is a long, flattened pear-shaped organ in the abdomen. It makes digestive enzymes and hormones, including insulin.

Causes

Cancer occurs when cells in the body divide without control or order. Normally, cells divide in a regulated manner. If cells keep dividing uncontrollably when new cells are not needed, a mass of tissue forms, called a growth or tumor. The term cancer refers to malignant growths. These growths can invade nearby tissues. Cancer that has invaded nearby tissues can then spread to other parts of the body.It is not clear exactly what causes these problems in the cells, but it is probably a combination of genetics and environment.

Risk Factors

Pancreatic cancer is more common in men, and in people aged 40 years and older. Other factors that may increase your chance of pancreatic cancer include:
  • Smoking and using smokeless tobacco, such as chewing tobacco
  • Alcohol abuse
  • Diabetes
  • Chronic pancreatitis, hereditary pancreatitis, or family nonpolyposis colon cancer syndrome
  • Family or personal history of certain types of colon polyps or colon cancer
  • Family history of pancreatic cancer, especially in Ashkenazi Jews with BRCA2 gene, which is associated with breast cancer
  • High-fat diet
  • Obesity, which may also reduce your chance of survival from pancreatic cancer

Symptoms

Pancreatic cancer does not cause symptoms in its early stages. The cancer may grow for some time before it causes symptoms. When symptoms do appear, they may be very vague. In many cases, the cancer has spread outside the pancreas by the time it is discovered.Symptoms will vary depending on the location and size of the tumor. Pancreatic cancer may cause:
  • Nausea
  • Loss of appetite
  • Unexplained weight loss
  • Pain—in the upper abdomen, sometimes spreading to the back (a result of the cancer growing and spreading)
  • Jaundice—yellowing of the skin and whites of the eyes, dark urine, tan stool, or stool that floats to the top of the bowl
  • Weakness, lightheadedness, chills, muscle spasms, diarrhea—especially if the cancer involves the islet cells that make insulin and other hormones

A randomized trial found that fecal microbiota transplantation had a higher rate of remission in patients with active ulcerative colitis than those who recieved placebo. Fecal transplantation is believed to help the intestine develop a healthy balance of bacteria in the gut which can help the intestine recover and function more effectively.
