Be Aware : About "PANCREATIC CANCER" : Rare Information and Causes

Pancreatic cancer is a malignant neoplasm of the pancreas. Each year in the United States, about 42,470 individuals are diagnosed with this condition and 35,240 die from the disease. The prognosis is relatively poor but has improved; the three-year survival rate is now about thirty percent, but less than 5 percent of those diagnosed are still alive five years after diagnosis. Complete remission is still rather rare. About 95% of exocrine pancreatic cancers are adenocarcinomas (M8140/3). The remaining 5% include adenosquamous carcinomas, signet ring cell carcinomas, hepatoid carcinomas, colloid carcinomas, undifferentiated carcinomas, and undifferentiated carcinomas with osteoclast-like giant cells.Exocrine pancreatic tumors are far more common than pancreatic endocrine tumors, which make up about 1% of total cases.

"PANCREATIC CANCER" Causes

Risk factors for pancreatic cancer include:

Age (particularly over 60)

Male sex (likeliness of up to 30% over females)

African-American ethnicity

Smoking. Cigarette smoking has a risk ratio of 1.74 with regard to pancreatic cancer; a decade of non-smoking after heavy smoking is associated with a risk ratio of 1.2.

Diets low in vegetables and fruits

Diets high in red meat

Diets high in sugar-sweetened drinks (soft drinks) risk ratio 1.87

Obesity

Diabetes mellitus is both risk factor for pancreatic cancer, and, as noted earlier, new onset diabetes can be an early sign of the disease.

Chronic pancreatitis has been linked, but is not known to be causal. The risk of pancreatic cancer in individuals with familial pancreatitis is particularly high.

Helicobacter pylori infection

Family history, 5–10% of pancreatic cancer patients have a family history of pancreatic cancer. The genes responsible for most of this clustering in families have yet to be identified. Pancreatic cancer has been associated with the following syndromes; autosomal recessive ataxia-telangiectasia and autosomal dominantly inherited mutations in the BRCA2 gene and PALB2 gene, Peutz-Jeghers syndrome due to mutations in the STK11 tumor suppressor gene, hereditary non-polyposis colon cancer (Lynch syndrome), familial adenomatous polyposis, and the familial atypical multiple mole melanoma-pancreatic cancer syndrome (FAMMM-PC) due to mutations in the CDKN2A tumor suppressor gene.

Gingivitis or periodontal disease

Ulcerative colitis

Australia and Canada being members of International Cancer Genome Consortium are leading efforts to map pancreatic cancer's complete genome.




Prevention

According to the American Cancer Society, there are no established guidelines for preventing pancreatic cancer, although cigarette smoking has been reported as responsible for 20–30% of pancreatic cancers.

The ACS recommends keeping a healthy weight, and increasing consumption of fruits, vegetables, and whole grains while decreasing red meat intake, although there is no consistent evidence that this will prevent or reduce pancreatic cancer specifically.In 2006 a large prospective cohort study of over 80,000 subjects failed to prove a definite association.The evidence in support of this lies mostly in small case-control studies.
