Cancer of the pancreas is both an acquired and a genetic disease. It is caused by changes (mutations) in DNA, which can be inherited or acquired; the inherited changes explain why cancer of the pancreas runs in some families whereas the acquired changes can result from exposure to carcinogens and/or an immune system which is depressed in some way, rendering it less capable of killing cancerous cells once they develop. Risk Factors


There are factors which can increase the risk of developing genetic mutations that may potentially result in pancreatic cancer. It has now become clear that cancer of the pancreas runs in some families: relatives of patients with cancer of the pancreas have an increased risk for developing pancreatic cancer themselves. For those with an increased risk due to this factor or a history of pancreatic cancer, preventive actions should be taken.

As many as 10% of pancreatic cancers are caused by inherited defects in the BRCA2 gene. One particular defect in BRCA2 (a mutation called 6174 del T) is found in 1% of Ashkenazi Jews which may explain the higher rate of pancreatic cancer observed in Jews as compared to Catholics or Protestants. Testing is now available for BRCA2 mutations.

Prognosis
Pancreatic malignancy has one of the highest mortality rates for cancer, being the fifth leading cause of cancer deaths in the United States. A full 80% of patients diagnosed with it die within a year.





Signs, symptoms & indicators of Pancreatic Cancer:
Symptoms - Bowel Movements  Pale stools

Conditions that suggest Pancreatic Cancer:
Metabolic  Jaundice

Organ Health

  Diabetes Type II
 There have been a number of reports that have suggested diabetics have an increased risk of developing pancreatic cancer. The reasons for this are not clear.

Symptoms - Cancer

  Pancreatic cancer (confirmed)

Risk factors for Pancreatic Cancer:
Addictions  Cigarette Smoke Damage
 Cigarette smoke contains a large number of carcinogens and therefore it should come as no surprise that cigarette smoking is one of the biggest risk factors for developing pancreatic cancer. For example, smoking during college has been associated with a 2 to 3-fold increased risk of pancreatic cancer.

Approximately 30% of all deaths from pancreatic cancer are attributable to cigarette smoking. Historically, males have had a much higher incidence of cancer of the pancreas. However, this difference is steadily decreasing as women smoke earlier and more heavily. There is approximately a 2-fold increase in the risk of developing pancreatic cancer with smoking and this risk is dose-dependent.

Metabolic

  Problems Caused By Being Overweight
 At least two studies have found that obesity significantly increases one's risk of developing pancreatic cancer. [JAMA. 2001;286: pp.921-929]

Organ Health

  Pancreatitis
 Long-term pancreatitis has been linked to an increased risk of pancreatic cancer. The reason for this association is not clear, but it is strongest in patients with inherited chronic pancreatitis.

  Consequences of Gallbladder Surgery
 Although there appears to be a significant risk of pancreatic cancer following gallbladder removal, there is some conflicting evidence.

Personal Background

  African ethnicity
 Studies in the United States have shown that pancreatic cancer is more common in the African-American population than it is in the white population. Some of this increased risk may be due to socioeconomic factors and higher levels of cigarette smoking.

Symptoms - Cancer

  History of pancreatic cancer

Symptoms - Food - Beverages

  (High) coffee consumption
 Studies linking coffee consumption with cancer are conflicting and inconclusive at this point, but there is a suggestion of a higher incidence of cancers of the pancreas, ovaries, bladder, and kidneys in coffee drinkers.

Symptoms - Food - Intake

  (High) luncheon meat consumption
 May, 2005: The University of Hawaii released a new study that shows people who consume processed meats have a 67% increased risk of pancreatic cancer over those who consume little or no meat products. The study was done over a period of seven years on nearly 200,000 people. Researchers pin the blame on sodium nitrite, a chemical used in nearly all processed meats, including sausage, hot dogs, jerkies, bacon, lunch meat, and even meats in canned soup products. Sodium nitrite is a precursor to highly carcinogenic nitrosamines -- potent cancer-causing chemicals that accelerate the formation and growth of cancer cells throughout the body.

Pancreatic Cancer suggests the following may be present:
Tumors, Malignant  Cancer, General

Pancreatic Cancer can lead to:
Metabolic  Jaundice

Recommendations and treatments for Pancreatic Cancer:
Digestion  Digestive Enzymes
 Although the body of evidence is small, an alternative treatment for pancreatic cancer has brought hope to a handful of patients and caught the attention of the National Institutes of Health (NIH) which is funding a five-year clinical trial. Based on this preliminary evidence that pancreatic enzymes kill pancreatic cancer cells, it would be prudent to ensure pancreatic sufficiency or use pancreatic enzymes supplementally when the risk of developing pancreatic cancer is increased.

Dr. Gonzales, M.D. reviewed and published the follow-up results of 11 patients who followed his treatment regime. They lived on average three times longer than expected. Gonzales said all the patients were in an advanced stage of the illness, and their conditions were inoperable. He further stated that "the survival rate at this stage is usually about 4-5 months, but the survival rate for the test patients was 17 1/2 months... I think the pancreatic enzymes do have a powerful anti-cancer effect. We do use diet (fruits and vegetables), we do use coffee enemas, we do use vitamins and minerals. I don't think any of those things kill cancer cells. I do think pancreatic enzymes do." [Nutrition and Cancer 33(2): pp.117-24]

Drug

  LDN - Low Dose Naltrexone

Preventive measures against Pancreatic Cancer:
Botanical  Green Tea
 Regular and substantial consumption of green tea may provide protective effect against this type of cancer.

Diet

  Increased Fish Consumption
 Study subjects who ate two or more servings of fish weekly had a much lower risk for esophageal, stomach, colon, rectum, and pancreatic cancers than those who avoided fish. In fact, the rates of these types of cancer were 30 to 50 percent lower among fish eaters. High fish consumption was also associated with lower risks for cancers of the larynx (30 percent lower risk), endometrial cancer (20 percent lower risk), and ovarian cancer (30 percent lower risk).

  Plant-Based Nutrition
 Diets high in meats, fried foods and nitrosamines may increase the risk, while diets high in fruits and vegetables may reduce the risk of pancreatic cancer.

  Caffeine/Coffee Avoidance
 Studies linking coffee consumption with cancer are conflicting and inconclusive at this point, but there is a suggestion of a higher incidence of cancers of the pancreas, ovaries, bladder, and kidneys in coffee drinkers.

GLOSSARY

Cancer
Refers to the various types of malignant neoplasms that contain cells growing out of control and invading adjacent tissues, which may metastasize to distant tissues.

Carcinogen (Carcinogenic, Carcinogenicity)
Any agent that is cancer-causing.

Chronic (Chronicity)
Usually referring to chronic illness: Illness extending over a long period of time.

Colon (Colonic)
The part of the large intestine that extends to the rectum. The colon takes the contents of the small intestine, moving them to the rectum by contracting.

Diabetes Mellitus (Diabetes, Diabetic, Diabetics)
A disease with increased blood glucose levels due to lack or ineffectiveness of insulin. Diabetes is found in two forms; insulin-dependent diabetes (juvenile-onset) and non-insulin-dependent (adult-onset). Symptoms include increased thirst; increased urination; weight loss in spite of increased appetite; fatigue; nausea; vomiting; frequent infections including bladder, vaginal, and skin; blurred vision; impotence in men; bad breath; cessation of menses; diminished skin fullness. Other symptoms include bleeding gums; ear noise/buzzing; diarrhea; depression; confusion.

DNA
Deoxyribonucleic acid, the large molecule that is the main carrier of genetic information in cells. DNA is found mainly in the chromosomes of cells.

Enzymes (Enzyme)
Specific protein catalysts produced by the cells that are crucial in chemical reactions and in building up or synthesizing most compounds in the body. Each enzyme performs a specific function without itself being consumed. For example, the digestive enzyme amylase acts on carbohydrates in foods to break them down.

Esophagus (Esophageal)
Commonly called the "food pipe", it is a narrow muscular tube, about nine and a half inches long, that begins below the tongue and ends at the stomach. It consists of an outer layer of fibrous tissue, a middle layer containing smoother muscle, and an inner membrane, which contains numerous tiny glands. It has muscular sphincters at both its upper and lower ends. The upper sphincter relaxes to allow passage of swallowed food that is then propelled down the esophagus into the stomach by the wave-like peristaltic contractions of the esophageal muscles. There is no protective mucosal layer, so problems can arise when digestive acids reflux into the esophagus from the stomach.

Gallbladder (Gall Bladder)
A small, digestive organ positioned under the liver, which concentrates and stores bile. Problems with the gallbladder often lead to gallbladder attacks, which usually occur after a fatty meal and at night. The following are the most common symptoms: steady, severe pain in the middle-upper abdomen or below the ribs on the right; pain in the back between the shoulder blades; pain under the right shoulder; nausea; vomiting; fever; chills; jaundice; abdominal bloating; intolerance of fatty foods; belching or gas; indigestion.

Immune System (Immune Response, Immunity)
A complex that protects the body from disease organisms and other foreign bodies. The system includes the humoral immune response and the cell-mediated response. The immune system also protects the body from invasion by making local barriers and inflammation. The process may involve acquired immunity (the ability to learn and remember a specific infectious agent), or innate immunity (the genetically programmed system of responses that attack, digest, remove, and initiate inflammation and tissue healing).

Kidneys (Kidney, Renal)
Bean-shaped organs, each about the size of a fist. They are located near the middle of the back, just below the rib cage. The kidneys are sophisticated reprocessing machines, each day handling about 50 gallons of blood to sift out about half a gallon of waste products and extra water. The waste and extra water become urine, which flows to the bladder through tubes called ureters. The actual filtering occurs in tiny units inside the kidneys called nephrons. Every kidney has about a million nephrons. In a nephron, a glomerulus -- which is a tiny blood vessel, or capillary -- intertwines with a tiny urine-collecting tube called a tubule. A complicated chemical exchange takes place, as waste materials and water leave your blood and enter your urinary system. The kidneys recycle chemicals such as sodium, phosphorus, and potassium and thus regulate their levels. Renal: Pertaining to the kidneys.

Larynx (Laryngeal, Voice Box)
The short passageway shaped like a triangle that is just below the pharyx in the neck.

Malignant (Cancerous)
Dangerous. Mainly used to describe a cancerous growth -- when used this way, it means the growth is cancerous and predisposed to spreading.

Mineral (Minerals)
Plays a vital role in regulating many body functions. They act as catalysts in nerve response, muscle contraction and the metabolism of nutrients in foods. They regulate electrolyte balance and hormonal production, and they strengthen skeletal structures.

NIH
National Institutes of Health.

Nitrosamine (Nitrosamines)
A chemical that may be formed from the metabolism of nitrates which are common preservatives used in processed foods.

Ovary (Ovaries)
Ovaries are about the size of an almond and lie on either side of the lower abdomen beside the uterus. They usually produce one egg each month and whether the egg is fertilized or not, the reproductive process follows a monthly cycle, with constant changes in various hormone levels, preparing another opportunity for conception. The ovary is responsible for most of the estrogen production in women. At menopause (sometime after middle-age), egg production ceases and hormone levels drop significantly.

Pancreas (Pancreatic)
Opposite the liver and behind the stomach, the pancreas has two main functions - to manufacture various enzymes for digestion, and to release hormones to help control the body's use of carbohydrates. It releases insulin to help each cell absorb glucose to burn as energy. In this way, insulin controls the amount of sugar (glucose) in the blood. Proper pancreatic function is very important: too much, too little, or no insulin production can be life-threatening. Some of the chemicals released by the pancreas are not hormones, but stimulate other glands to make hormones. Once again, balance is necessary. Nutritional requirements for the pancreas are many. Research indicates that chromium vitamins C, E, B-complex, calcium, magnesium and potassium are especially important.

Pancreatitis
Inflammation of the pancreas. Symptoms begin as those of acute pancreatitis: a gradual or sudden severe pain in the center part of the upper abdomen goes through to the back, perhaps becoming worse when eating and building to a persistent pain; nausea and vomiting; fever; jaundice (yellowing of the skin); shock; weight loss; symptoms of diabetes mellitus. Chronic pancreatitis occurs when the symptoms of acute pancreatitis continue to recur.

Precursor (Precursors)
A biochemical substance, such as an intermediate compound in a chain of enzymatic reactions, from which a more stable or definitive product is formed.

Sodium
An essential mineral that our bodies regulate and conserve. Excess sodium retention increases the fluid volume (edema) and low sodium leads to less fluid and relative dehydration. The adult body averages a total content of over 100 grams of sodium, of which a surprising one-third is in bone. A small amount of sodium does get into cell interiors, but this represents only about ten percent of the body content. The remaining 57 percent or so of the body sodium content is in the fluid immediately surrounding the cells, where it is the major cation (positive ion). The role of sodium in the extracellular fluid is maintaining osmotic equilibrium (the proper difference in ions dissolved in the fluids inside and outside the cell) and extracellular fluid volume. Sodium is also involved in nerve impulse transmission, muscle tone and nutrient transport. All of these functions are interrelated with potassium.

Stomach
A hollow, muscular, J-shaped pouch located in the upper part of the abdomen to the left of the midline. The upper end (fundus) is large and dome-shaped; the area just below the fundus is called the body of the stomach. The fundus and the body are often referred to as the cardiac portion of the stomach. The lower (pyloric) portion curves downward and to the right and includes the antrum and the pylorus. The function of the stomach is to begin digestion by physically breaking down food received from the esophagus. The tissues of the stomach wall are composed of three types of muscle fibers: circular, longitudinal and oblique. These fibers create structural elasticity and contractibility, both of which are needed for digestion. The stomach mucosa contains cells which secrete hydrochloric acid and this in turn activates the other gastric enzymes pepsin and rennin. To protect itself from being destroyed by its own enzymes, the stomach’s mucous lining must constantly regenerate itself.
