In view of in recent years our country large intestine of cancerous incidence of a disease ceaseless and elevatory, and the current situation that cure rate did not improve apparently, we think to begin concerned large intestine the popular science conduct propaganda of knowledge of cancerous prophylaxis and treatment is very necessary. Be here row of relevant knowledge of propaganda and education now, hope everybody masters the precautionary knowledge of this disease, make good large intestine jointly with the doctor cancerous prevention and cure works, make the contribution of some of in one's power to improve the healthy quality of the whole people.

1. Suffer from large intestine ill factitious what of cancer is more and more? What reason is this?

Here has two groups of data: One is 20 years of large intestine of 5 provinces city the comparison of incidence of a disease, a comparison that is number of nearly a few years of census (add two pieces of slide) . From this two numbers can explain, cancerous sicken number has our country large intestine to increase a current apparently really. According to the research result of each national experts, most person thinks agelong high protein, tall adipose the happening that is helpful for large intestine with habit of low cellulose food. Of course, also not be to say agelong high protein, tall adipose can produce large intestine with habit of low cellulose food cancer. Other is relevant element, be like old ulcerous sex knot does not heal; Familial in much person suffers from large intestine cancer or polypous disease; Cystic excision 10-20 year above; After next abdominal and radiative cure; Chronic schistosome infection also with large intestine cancer comes on about.

2. Someone says " those who eat is better, get large intestine more easily cancer " . Is this statement right?

World various places and different country large intestine cancerous incidence of a disease can differ 10 times above. Economy developeds area and country, like the large intestine of North America, Western Europe, Australia and New Zealand cancerous incidence of a disease all exceeds 25-35/10 10 thousand, nearly 20 years, it is the Japan of tall hair originally, as the rapid development of its economy, this country the addition of cancerous incidence of a disease already exceeded large intestine, according to statistic, arrive from 1969 1981, cancerous mortality increased Japanese male large intestine 44% , the female increased 40% . The incidence of a disease of contrary India is 1-3/10 only 10 thousand, large intestine of certain Africa country cancerous incidence of a disease even under 1/10 10 thousand. Statistical data of nearly 30 years shows our country, cancerous sicken leads large intestine already the <10/10 from 60 time 10 thousand, rise to the 10 thousand above of 20/10 of 80 time, shanghai area large intestine cancerous mortality increased to 1989 from 1972 75% , according to expert estimation, after 2000, large intestine cancer comes on number will compare 80 time tower above 1. 45 times. Be opposite according to us our country northern region the census data of ten town, city especially big city, large intestine cancerous incidence of a disease is apparent prep above a wide place in the road and country. In the city, the crowd incidence of a disease with manual little activity the crowd with much activity of prep above physical strength. To large intestine from each countries cancerous cause of disease learns to study the result looks, tall food of adipose, high protein, motion decreases, environmental pollution and unhealthy addiction all with large intestine of cancer come on about, and the occurrence of afore-mentioned social circumstances has certain connection with economic progress again, accordingly, somebody thinks those who eat is better, get large intestine more easily cancer. In fact large intestine cancer and other cancer are same, their happening is the result of environmental element and genetic element interaction. With respect to dietary itself character, structure of food and drink of tall adipose, high protein, low fiber may send large intestine in hurried cancerous side has certain effect.

3. Since tall adipose, high protein and little fiber (coarse food grain, vegetable and fruit are tall fiber food) dietary structure makes the person gets large intestine easily cancer, is so what kind of cookbook " healthy diet " close?

American Ministry of Agriculture recommended recently " pyramid " the food structure plan of type, they think such food structure is helpful for large intestine cancerous precaution. Tower bottom is comprised by all sorts of cereal, cooked wheaten food, rice, of the tower mid it is vegetable and fruit, tower upside is the flesh kind, rasorial, aquatic product, egg kind, legume and milk products, tower needle is tall grease food. Actually, structure of this kind of food is an Asia, especially the daily diet of our country. From precautionary large intestine cancer this angle sets out, the dietary construction that holds our country convention is " healthy diet " .

Organization of European cancer precaution and alliance of international nutrition science also put forward to suggest as follows:

1. Decrease adipose kind alimental is absorbed (include animal oil and vegetable oil) , replace the carnivorous with animal overmuch oil with milk products of fish, birds, lean lean, low fat, in order to boil, content of steamed wheaten foods replaces deepfry provision.

2. Increase green part of a historical period kind with the root kind vegetable, fruity is absorbed.

3. Eat the food with starch and much fiber more.

4. Carry appropriate weight.

5. Everyday salt is absorbed under 5 grams.

6. Eat fresh food more, eat less bloat, fume food, do not eat mildewy food.

Beverage of little drink spirituosity.

4. can the person get large intestine easily cancer?

It is to point to second too little or defecate difficulty, work etc expression. Generally speaking, 2-3 day defecate, if eduction unobstructed also cannot be called. Our mucky at one's convenience contains a kind of carcinogenic substance, call on medicine " 2 class cholic acid " , it originates hepatic excretive is biliary. Take food when us, when eating the food with much oil especially, gallbladder contracts, what eduction stores is biliary, help aid digestion. The bacterium in alvine antrum decomposes these bile that enter alvine antrum for " 2 class cholic acid " , be stationed in in staying at excrement and urine, person in alvine antrum " 2 class cholic acid " contact for a long time with alvine mucous membrane, increased its to stimulate the opportunity of mucous membrane ceaselessly. Tell from this angle, can be helpful for large intestine cancerous happening. Of course, in excrement and urine besides " 2 class cholic acid " beyond, still have a lot of be digested the following food is residual with the bacterium. The toxin that the bacterium produces and the poisonous result that are seen by bacterial ferment, stay for long as a result of in alvine antrum, all have adverse effect to human body to the absorption of the stimulation of alvine mucous membrane and partial water-solubility material. Although cannot say to be able to cause large intestine cancer, but can say to be in the effect that large intestine has add fuel to the fire on cancerous happening. For this, nurturance is fixed the habit of defecate, the happening that prevent, in large intestine there also is certain sense on cancerous precaution.

5. Can the patient that has become cystic excision operation get large intestine easily cancer?

The person's gallbladder is just like to store biliary " reservoir " , bile of hepatic at ordinary times excretive stores for the most part here, after we have a meal, after eating the food with oiliness much fat especially, gallbladder is contractive, emit into the bile that store alvine path, play helps aid digestion, digestive effect. If gallbladder was excised, the bile that liver secretes did not have the place that store, then bile discharges the path that enter bowel continually. Be like in front what say, the bacterium in entering the bile that bowel to be by bowel is decomposed, generation has the effect that cause cancer " 2 class cholic acid " , this kind of carcinogenic substance all the year round mucous membrane of action Yu Chang, make likely suffer canceration of exciting alvine mucous membrane. According to the west a lot of research data report, this changes cancerous process needs 10-15 probably year above. But also a few investigator are held reject an attitude, they observed on 1000 did cystic excision and the patient that had not become this kind of operation, large intestine suffers from in discovering these two kinds of people opportunity photograph of cancer is about the same. Accordingly, so far, the patient that still cannot say for certain to had done cystic excision gets large intestine more easily cancer.

6. Can chronic knot evolve for large intestine cancer?

Normally the disease all long-term, bellyacke calls people to written guarantee chronically. Actually chronic abdominal pain, differ choose a site for the capital is " chronic knot " , even if doctor diagnoses " chronic knot " also not be with large intestine cancer is concerned. Written guarantee chronically with a kind when cancer concerns large intestine truly, say on medicine for " cankerous sex writtens guarantee " . This kind of disease is compared relatively in our country little, its main symptom is bellyacke, , mucky at one's convenience has blood or purulent blood, the person that weigh can have have a fever. Once sicken, much delay is longer cannot heal. Colonic lens examination can discover to there are extensive ulcer and inflammation in large intestine. This kind of patient passes standard treatment of the doctor, great majority can restore, few number illness is heavier, old in the patient of cankerous sex knot that does not heal, have than normal person more opportunities produce large intestine cancer. According to data statistic, two elements and canceration concern under more close:

Pathological changes limits heals big, the danger of canceration heals tall (sicken after 20 years, full ties patient changes cancerous opportunity is compared left half ties is one times louder, the average age of canceration also compares latter early 5-10 year) ; The time that ulcerous sex writtens guarantee defer does not heal grows more, the opportunity of canceration heals much, after sicken canceration opportunity of before 8 years only 1% the following, ever since, the opportunity that has cancer every year increases 0. 5-1% , 20 years above canceration opportunity can amount to 5-10% . Accordingly, the sex of completely colonic ulcer that 10 years above does not heal writtens guarantee, should be regarded as " the disease before cancer " , should follow closely visit, cure.

7. Is radiation treated (does common weigh diathermy) can be you caused?

A lot of research data show, female reproduction organ (ovarian, uterus) after tumor accepts radiation to treat, the opportunity that have increases apparently. Accordingly, have next abdominal and radiative treatment (diathermy) historical female should raise vigilance, once appear rectum symptom (n/med having blood in one's stool, change of habit of straining, defecate) should undertake alvine lens is checked in time.

Radiation causes do not have familial collect a gender, go up with another kind of medicine call " transmissibility is not cancer of polypous sex colon " different, latter has outstanding genetic characteristic. This kind of patient suffers from large intestine cancer, but at the same time or tumor of female reproduction organ has when differring. Because this kind of tumour has familial the characteristic that gather, accordingly, carry out cure to oneself not only, to its relative, also should check cure (will telling later) .

8. Large intestine is cancer genetic?

Science considers to prove, disease of human great majority all has the effect of genetic element. Except is hurt and outside, almost all diseases suffer environment and heredity the influence of two elements, just some of disease suffers environmental element to affect more, another some of disease suffers genetic element effect more outstanding and. Large intestine cancer is not exceptional also, there is large intestine in the individual's relative carninomatosis person, criterion he falls in certain condition, if eat high protein, tall adipose, little fiber for long (rice of essence of life, flour and rice) food, more opportunity produces large intestine cancer. Of course, large intestine cancerous happening also is not simple 1+1=2 (genetic + large intestine of = of fast adipose food cancer) , however a many element, much measure, extend the process that cancerous element accumulates for long.

Internal cause is metabolic basis, external cause is metabolic condition. Devoid large intestine genetic background of cancer, even if is caused the effect of cancerous element, get large intestine not easily also cancer. Conversely, have large intestine of cancer familial history, get large intestine easily below the action of the certain factor that cause cancer cancer. Accordingly, be like a relative, there is large intestine in directly-related members of one's family -parents especially when carninomatosis person, familial in each member should accept relevant inspection regularly. When necessary, have treatment even, in order to prevent large intestine cancerous happening.

9. Why some large intestine cancer is easy and genetic, those large intestine is cancer easy and genetic?

Had mentioned above, should say cancer suffers all large intestine genetic element influence, but their genetic strength is different. Have two kinds of large intestine the strength of cancerous heredity is very great: Call on the first kind of medicine " polyp of sex of tumour of familial sexual gland is ill " , the 2nd kind cries " transmissibility is not polypous sex large intestine cancer " . Tumor is in these two kinds of large intestine all large intestine holds few number only in cancer. Former come on the age has 20 years old on average only, can have in large intestine thousands of adenoma (a kind of when grow from alvine mucous membrane benign tumor) , appear after these benign tumor 10 years, among them some begin canceration, as the elapse of time, the person that has this kind of disease all is met sooner or later canceration, and familial in a lot of members all have same disease. The person that has this kind of disease also can suffer from osteoma at the same time, with brain tumor. Once discover this kind of disease, patient and his directly-related members of one's family -parents needs to be followed for a long time visit, make necessary inspection. Latter (transmissibility is not polypous sex large intestine cancer) come on the age compares general large intestine cancerous early 15-20 year, cancer happens in more right half colon, there are a few cancers at the same time in large intestine sometimes (call much formerer hair cancer) , operation hind has a relapse very easily. In him familial in often also appear other cancer, be like, ovarian cancer, , pancreatic cancer, etc, so someone call his " cancer is familial and integrated proof " .

Above these two kinds of large intestine cancerous transmissibility all very strong, once familial in appear this kind of tumour, all directly-related members of one's family -parents all should reach the patient the hospital undertakes checking, accomplish diagnose early discovery, early, the purpose of early treatment.

10. Be large intestine " polypous " metropolis canceration?

Above all we should make clear what is " polypous " . Alleged " polypous " , it is to point to intestines in (mucous membrane face) all sorts of apophysis thing that grow. Tell from medicine, sex of tumour of this kind of polypous cent and blame tumour sex two kinds. Before one kind cries " adenoma " , it is true benign tumor. A kind of polyp is not tumor after, include phlogistic sex polyp, proliferous sex polyp to wait, the happening of they and cancer did not concern.

So, can all adenoma turn into cancerous close? Actually, not all adenoma should turn into cancer. Change the most easily cancerous is in front mention " polyp of sex of tumour of familial sexual gland is ill " , this kind of adenoma can have abdominal pain, , n/med having blood in one's stool, also can do not have a symptom, till discovery of the ability after canceration. According to observation, this kind of disease happens in 20 years old or so more, 33 years old control occurrence symptom, 39 years old control canceration, average age has 42 years old only when death. Have research discovery, there is 80% to appear in this kind of patient " sex of congenital retinal pigment is epithelial and proliferous " , as a kind of mark, the inspection that skeptic can pass an eye (ophthalmoscope is checked) , discovery has this ill thread. Because this kind of disease has familial and accumulative sex, consequently if familial in have one individual diagnose, other member should have relevant examination (include eye ground to check) . Be in this kind " adenoma " in, have some of amalgamative existence skin, muscle, skeleton or cerebral tumor, some is amalgamative have black fleck of the skin and mucous membrane (the pigment of the palm and lip is ad cool-headed) , some companion have fingernail atrophy, with skin black fleck. Because polyp is long,be inside bowel, do not pass special inspection cannot diagnose, but can remind us to look for a doctor through afore-mentioned show that have a feature.

Besides above had told " polyp of sex of tumour of familial sexual gland is ill " beyond, great majority " adenoma " genetic possibility is not distinct. Call this kind of adenoma on medicine " send out sexual gland tumour " , the size of this kind of adenoma and canceration have certain dependency, ever somebody statistic 4570 adenoma, the diameter is less than 0. 9cm person, canceration rate is 0. 3% ; 1-1. 9cm person, canceration rate is 3. 6% ; 2-2. 9% person, for 6. 8% ; The person that be more than 3cm, for 12. 4% . This shows, tumour body heals big, change cancerous opportunity heals big. In addition, pass microscope inspection, if discover adenoma is " villiform adenoma " , change cancerous opportunity is very great (it is about 40% ) , if " adenoma tubal account " change cancerous chance is very little (5% the following) . Be not tumor sex polyp, especially the diameter is less than 0. The small polyp of 5cm can turn into scarcely cancer.

11. Schistosomiasis and large intestine is cancer relative?

Ever the large intestine that somebody discovers schistosome popularity area cancerous incidence of a disease is higher, think this is mucous membrane of Yu Chang of schistosome egg deposit consequently, cause canceration of the place mucous membrane through mechanical sex or chemical sexual excitement. Return somebody to discover, the place of schistosome egg deposit of alvine mucous membrane has inchoate canceration sign. Basis afore-mentioned these discovery, a few people think bowel schistosomiasis can cause large intestine cancer. But also have a lot of data prooves, the large intestine of schistosome popularity area cancerous incidence of a disease not area of prep above other, the cancer that place of schistosome egg deposit discovers and the cancerous occurence rate that are not place of schistosome egg deposit do not have apparent difference. Anyhow, whether can schistosome bowel disease cause large intestine cancer does not have final conclusion, but regard path of a kind of bowel as chronic exciter, active cure schistosomiasis still is very necessary for cancerous precaution to large intestine.

12. Large intestine is tumor large intestine cancer?

At ordinary times tumor includes the large intestine that we say benign and malign two kinds. The benign tumor of large intestine also cries " adenoma " , it is large intestine gland body (mucous tissue is secreted in large intestine) excessive hyperplasia. This is a kind of not big to human body harm benign tumor. But the likelihood that because it has further progress,is cancer, accordingly, it makes be on medicine " the pathological changes before cancer " . Once discover this kind of tumour, although it is not malignant tumor, also should be treated actively and check.

13. How does Mo know whether he got large intestine cancer?

Large intestine main symptom of cancer is to n/med having blood in one's stool, it is next, , bellyacke, weight

Issue demote. Once appear some of symptom, answer to go to a hospital seeing a doctor instantly. According to large intestine of domestic case count of cancer by accident examine rate is as high as 41. 5% . A main reason is people to large intestine cancerous symptom lacks understanding, incur loss through delay when seeing a doctor. Because examine a doctor to lack vigilance,also having partial case is, scanty at serious examination, n/med having blood in his stool to be by accident, regard purulent blood as dysenteric cure. Somebody analysed large intestine cancerous patient from the symptom arrives the time of diagnose is: The diagnose inside a month person only 8-10% , 1-3 month person 25% , 3-6 month 64. 3% .

14. Hear the lens that do bowel is very afflictive, does cancerous census need large intestine examination of the lens that do bowel?

For the person that joins general investigation to great majority, want to do laboratory test of excrement and urine 3 times only, the blood that whether there is an eye to lose sight of in seeing excrement and urine (say on medicine " concealed blood " ) . If this is planted " concealed blood " , need to make colonic lens inspection, the reason with deciding haemorrhage further is alvine cancer! Or, knot, polypous. If do not have this to plant " concealed blood " , do not need to undertake alvine lens is checked. Colonic lens examination is a kind of diagnostic method not only, also be the precautionary method of method of a kind of treatment and alvine cancer. Compare with photograph of cancer sufferring from bowel, the anguish that colonic lens checks is negligible apparently. With respect to itself of alvine lens examination character, unless the patient's colon passes,grow or scrutator technology not

Skilled, won't have too great anguish generally speaking.

15. The patient that for what sees a doctor to the hospital is already medium mostly, terminal patient? Inchoate what does cancerous treatment have to differ as a result with terminal large intestine?

Because of inchoate large intestine cancer often does not have a symptom; Occurrence symptom of a few patients (even doctor) thinking by accident is, dysenteric, with the knot. Once long treat do not heal, when doubt and cancer, the disease already arrived medium, terminal.

Inchoate cancer surgery (can leave an operation in alvine lens even) hind survive 5 years rate can amount to 90-95% , and terminal cancer only 10%

16. How is ability obtained inchoate diagnose?

Of healthy person have general investigation regularly (healthy medical) ; Have necessary treatment to the disease before cancer (the cure that if be opposite,sex of adenoma, ulcer writtens guarantee) ; To large intestine cancerous directly-related members of one's family -parents undertakes genetics is monitored, it is to obtain inchoate diagnostic main avenue.

17. How does Mo undertake large intestine cancerous census?

Census is periodic actually only ill checkup. This kind of checkup also is not all people to want to check, different object has diverse examination demand. For example, the person do not have a symptom of 50 years old of above all should undertake annual census, the method of census is to do excrement and urine to check first (laboratory test of the blood that be like concealed) , once test of mucky concealed blood is positive, answer to accept alvine lens inspection instantly. Have large intestine cancer is familial history the person should begin general investigation from 40 years old. The person that there are many malignant tumors in directly-related members of one's family -parents, should undertake relevant gene detects check with necessary alvine lens. Some are familial should from 20-25 year old be about to have afore-mentioned examinations.

18. What symptom explains the likelihood sufferred from large intestine cancer?

Common symptom of cancer has large intestine n/med having blood in one's stool, , bellyacke, abdominal bump, ascites is waited a moment. Do not be equal to of course appear afore-mentioned symptoms have to large intestine cancer, because of other a lot of diseases all can have these symptoms. But, once appear these circumstances, have the person of these expression continuously especially, must see a doctor as soon as possible, so that make clear the pathogeny, cure of incur loss through delay. What emphasize even is a lot of inchoate large intestine cancer does not have a symptom, never think, do not have a symptom to do not have disease namely.

19. Can cancer prevent large intestine? How to prevent?

Large intestine cancer can prevent. Cancerous precaution can have large intestine at least two kinds of method: The pathogeny learns precaution and large intestine inchoate discovery of cancer. A moment ago had told, the benign ill that has known bad dietary habit and easy canceration now is large intestine hair cause of disease of cancer because. Build good dietary convention, treat the disease of easy canceration actively, have clear large intestine cancer is familial history person, accepting genetics to forecast is the pathogeny learns to prevent. Attend periodic health body actively to check (census) , it is inchoate discovery large intestine effective method of cancer.

20. Sufferred from large intestine cancer should how Mo cure?

Large intestine first treatment method of cancer is operation cure. Because of large intestine cancer great majority is polypous model, if cancer happens in polypous top, and it is inchoate cancer, can issue excision in alvine lens, need not open an abdomen to excise colon. If cancer happens in polypous root ministry, or cankerous sex cancer or the cancer that doubt has move must open an abdomen to excise alvine canal. Whether does operation hind undertake changing cure even, want to see cancer have the integrated case of the differentiation degree that does not have move, cancer and patient. The choice of these methods wants to be mastered by the doctor. Compensatory or what at present popular immune therapeutics, traditional medicaments therapeutics also can regard afore-mentioned cure as the method is auxiliary, the effect is treated in what opportune opportune moment is assisted or add powerful bowel cancer.
