Contract the pancreas cancer is who ask for of disaster

Pancreas cancer because the part is special and difficult to discover in earlier period, is currently ill malignant tumor of a higher kind of the rate is in the world.Domestic and international have been already start to the research of pancreas cancer dangerous factor from the 90's in last century, mainly have a following factor:

Behavior factor

Smoking already drive generally accepted is the behavior dangerous factor of pancreas cancer.The United States at 1993 glue a rightness 17633 white mans to carry on a brigade row research, result manifestation pancreas cancer of risk with smoke cigarette quantity of increment but ascension, the danger which smokes cigarette more than 25 smoker occurrence a pancreas cancer everyday is a smoker not of 400%.The crowd case that Shanghai City carries on in 1996 checks against the risk of the occurrence pancreas cancer of the smoking crowd of the research detection at the ascension, and smokes cigarette to pay a number and smokes cigarette time limit increment but goes up with everyday.The research of Taiwan also hints that the oriental more and greatly smokes cigarette quantity to present to show Zhao up-trend to the risk of occurrence pancreas cancer.The recent crowd case checks against a research to also support a tobacco's cancer-causing function for pancreas.So the control smoking prevent°froms one of the pancreas cancerous important measure.

Contain different conclusion towards drink, drink coffee and green tea and pancreas cancer relation.The Italian pancreas cancer case checks against research detection alcohol and drink green tea and pancreas cancer without the obvious relation, 1~2 cup coffees don't increase the danger of pancreas cancer everyday, everyday 3 cup coffee would light degree increment risk;Another a researcher discover American common crowd alcohol the level isn't a pancreas cancer of dangerous factor, but drink to excess will increase a risk, particularly is to difficult endure.The difference of above-mentioned conclusion may be because alcohol or drink coffee what the dissimilarity on the quantity result in.The female drinks green tea and can show the danger that the Zhao lowers a pancreas cancer, but male only at in etc. take tea observe a risk to descend.

The relation which theres is researcher to the sex and the human race and the pancreas cancer carries on a research, discover female and black of obese's can increase a pancreas cancer dangerous and 50% ～s be 60%s, and should dangerous still absorb along with the calories of the increment present up-trend of have the covariance meaning and explain the obese is a pancreas cancerous of one of the dangerous factors.

Inherit a factor

The international cancer think factory(IARC) research discovers that 7.8% pancreas cancer sufferers have a household history, the matched control onlies have 0.6%, both differ 1300%, and can't use an environment factor an explanation.Researcher's Acadiana region(pancreas cancer Gao Fa Qu) in the south of Louisiana in the United States does review inquisition and show local white man as a result with not descendant's American the male and female and average outbreak rate be all high at the national level.16% pancreas cancer sufferers have more than an one class relatives household histories.

Hereafter have again some the researches discover to have a pancreas cancer the household history in one class relatives of individual, there is self-moving pancreas cancer higher risk.So the further research has something to do with pancreas cancer of heredity and environment's handing over with each other a function be necessary.This kind of high Wei crowd identifies and will contribute to a clinical implement to to sex Shai check project and establishment to prevent sex from interfere to reduce the death rate of the household pancreas cancer.For household phenomenon, people doubted to be a gene to take place a mutation.

Environment factor

Local someone adopts a case to check against a research method to visit inquisition towards being engaged in the worker whom the rubber factory tire and galoshes create to carry on for 23 years of with, the research think have something to do with pancreas cancer the rubber compound may be a melting agent with second nitric An.Same of the research also discovers and expose three chlorination hydrocarbon the melting agent take place gall pancreas the dangerous factor of the cancer.Return another someone put forward and drop down from the grass and the tree the thing(like insect and herbicide) may also increase the danger of pancreas cancer.

Someone in 1998 report way, there is 65% pancreas cancer in 92 histologies confirm of the pancreas cancer sufferer sufferer the You door is spiral rod bacteria serology masculine gender, but stomach cancer the sufferer is 69%, both have no the covariance learn difference.But with knot, rectum cancer with normally check against to compare to have to show Zhao difference.The pancreas cancer sample microscope check has never discovered a You door the spiral rod bacteria exist of proof.Hint the You door has relativity between pancreas cancer and spiral rod bacteria infection.Though have male of related function and physiology reason, still need to be do a great deal of the research of prospect to make sure with valuation You door spiral rod bacteria conduct and actions cancer-causing dangerous factor of latent.

Diabetes

Whether diabetes is what the dangerous factor of pancreas cancer is to have a controversy or not.All the diabetes taken place before the pancreas cancer diagnose all is the non- insulin dependence type diabetes.Hint pancreas cancer sufferer of the diabetes much takes place in the cancer to take place of in the near future calculate is cause by the cancer of, not the dangerous factor of pancreas cancer.Someone makes pancreas cancer and bone neck bone fracture and knot, the rectum cancer age and sex to form couples a comparison, think the long-term diabetes fell ill a rate and increase in the pancreas cancer the sufferer.As a result think that the relation between pancreas cancer and diabetes may be a kind of occasional phenomenon, the diabetes isn't the dangerous factor that the pancreas is bad to change.But someone put forward and valued non- typical model diabetes(have no the household history of diabetes, have no obese and insulin to depend on fast make progress) for the pancreas cancer to express in early days, in order to at the tumor of the earlier period diagnose and was still and can be cut off by the surgical operation and cure because of the tumor in earlier period.

Recently, someone cultural heritage of overview 1970-1999 years, result manifestation glycouria patient pancreas cancer of frequency compare general crowd Gao, greatly parts of cultural heritages support above for 5 years diabetes increment occurrence pancreas cancer the standpoint of the danger.As a result hint diabetes is hereafter take place a pancreas cancer of dangerous factor.

People also doubly pay attention to in the pancreas cancer nascent function to the insulin.The Fisher research insulin is subjected to the existence and the influence of the insulin upon the tumor cell stub of body in 1996, research confirms that all 6 cell stubs have insulin to be subjected to a body, and research these are subjected to a body for adapt insulin dependence to increase in the cell propagate the function.Japan and the age mark of non- descendant American turned death rate to sharply increase Gao last century and hinted that the pancreas cancer completely can prevent°from.Combine the athletics toughen of the low insulin respond meal, weight control with don't smoke cigarette, and other can recommend of reason etc., can dramatic reduction pancreas cancer of death rate.Someone has already discovered that having a sugar metabolism the sufferer of the abnormality(BE gone up a circumstance assurance by the after meal blood sugar) will increase occurrence pancreas the danger of the cancer.There is another the author's data and the pancreas cancer-causing function in of high insulin blood disease key the function be consistent and particularly go up in the weight index number of non- diabetic middle.

Chronic pancreatitis

Diverse analysis shows that various type pancreatitis or alone chronic pancreatitises all have dangerous relativity of show the Zhao, and be free from other change to measure(like gallstone, drink to excess with discrepancy hospital etc.) influence.Hint pancreatitis disease of the history constituted hereafter take place the pancreas cancer obvious danger.That danger diagnoses ex- time to shorten but increases along with the cancer and explain a small pancreas cancer first meeting drive misdiagnosis is pancreatitis.

Digest way surgical operation

The postoperative to digest way pancreas cancer is dangerous to also have inconsistent viewpoint.Silverman etc. does a crowd case to check against a research detection in the United States, the cancer diagnoses ex- gall bladder to cut off 20 years above, the danger increases 70%, the risk which has 12 bowels and stomach ulcer the sufferer almost increased and accept stomach excision surgical operation a treatment of with don't accept the dangerous homology of surgical operation.The nonsupport stomach excision is the dangerous factor of pancreas cancer.

But someone to the 2633 stomach in Amsterdam cut off the sufferer's research discover it the danger increase 1.8, the stomach cut off behind the partition be above for 35 years, this is dangerous to increase gradually 3.6.Author's research thinks that the sufferer who once does stomach ulcer surgical operation has higher occurrence pancreas the danger of the cancer, particularly is a partition after operation is above for 20 years.

The dangerous factor identify is prevent°from the pancreas cancerous important link, control a dangerous factor with identify high Wei crowd is to prevent°from the pancreas cancerous important strategy.It will contribute to the existence period which prevents the pancreas cancerous occurrence and exaltation pancreas cancer from sufferer.
