Which crowds does the large intestine cancer "love" top?

The clinical doctor's understanding to the high Wei crowd would contribute to diagnose in early days and carried on to the high Wei crowd inspect, the census was advantageous to lower a large intestine cancer of outbreak rate and death rate.
Have a bowel way the crowd of the symptom
Under the large intestine cancer gradually familiar circumstance, the clinical doctor slices and can't drop with the light heart to the patient who has then blood and moves bowels a Pin number and moves bowels symptoms, such as sticky liquid and stomachache...etc. and imprudently diagnose for the hemorrhoid, enteritis...etc..At to have then blood, stomachache or move bowels a habit a change etc. the patient of the symptom does a colon mirror a check after discover, 8.6% patients suffer from a large intestine cancer, 25% patients suffer from large intestine gland lump, but generally Euro-American have no symptom crowd of adult large intestine cancer census in, large intestine cancer of check a rate as 0.2% ～s 0.4%.Their comparison can very clearly the elucidation have a bowel way the symptom to belong to high Wei crowd.
Large intestine cancer Gao Fa Qu of medium, old people
The outbreak rate of large intestine cancer at 40 years old hereafter with age growth but quick ascension.Many data all hint that the outbreak danger of 40 years old later large intestine cancer obviously rises, the age more old risk is also more old.Under the sistuation that now large intestine cancer is tend to much see, clinical doctor to in, when the old people appear then blood and move bowels the habit change, stomachache, anemic etc. symptom, all should watch out for, should early have a related check.
Large intestine gland lump patient
The large intestine gland lump belongs to before the cancer a pathological changes, the research of most thinks that the large intestine cancer of above 80%'s fasten is since then turn into by the large intestine gland lump, past give description in this point.
In the large intestine cancer in earlier period, gland lump's existence of the organization is very widespread, gradually develop along with the cancer, originally exist of gland lump the organization is eroded breakage gradually, so focus in can not discover the gland lump that the remnants remain organization.Most researches think currently and the large intestine cancer of above 80%'s fasten is since then turn into by the large intestine gland lump.Produce gland lump first on the large intestine mucosa, turn into a cancer to need 5 years from the gland lump above, average 5~10 years, but also the whole life constant.Because the occurrence of the large intestine cancer needs first through gland lump period, so if can check a gland lump combine to take off in addition to, then can avoid the occurrence of large intestine cancer.
The large intestine mucosa takes a post the Tu that can see without the aid of instruments to rise, in spite of it size, shape and histology type, all call it as polyp.The pathologic full general polyp is divided into a new-born thing polyp(namely gland lump) polyp with not- new-born thing.(include to increase born nature polyp, burning disease polyp, wrong Gou lump polyp etc.)The gland lump has 70% ～s 80% in all large intestine polyps, the histology slice of gland lump often it is thus clear that floss form composition.(the department stretches out many slender branches from the focus Ji, and it is thus clear that have abundant of the sticky liquid secrete)According to the floss form in the gland lump the comparison dissimilarity share by composition but is divided into gland lump tube form gland lump(the floss composition have below 20%), hybrid sex gland lump(floss form the composition has 20% ～s 80%), the floss form gland lump.(floss form the composition have above 80%)Because the different part its floss form composition of same gland lump distribute how much different, so the different part pliers take pathologic diagnosis of live the check can different, so only cut off the whole gland lump and careful check behind then can make sure to why grow gland lump.The tube form gland lump has 70%, the floss form gland lump and the mixture sex gland lump around to have 20% and 10% respectively in the gland lump of clinical detection.
1.large intestine gland the cancer of the lump change:The large intestine wall constitutes to°from the mucosa layer, mucosa muscle layer, mucosa bottom layer, proper muscle layer and the syrup film layer.Mucosa muscle the layer be very thin, is constitute by minority a few smooth muscle fibers, come close catgut gland the bottom of the tube and lie to become both it boundary between the mucosa and the mucosa bottom layer.The layer starts from the mucosa muscle it is thus clear that lymphoid tube, but these are lymphoid the tube doesn't get into a mucosa layer.Mucosa bottom layer from loose knot Di organization constitute, contain abundant of lymphoid tube.Gland lump's fasten is taken care of the last skin lump by the gland in the mucosa layer to change but becomes.While still being limited by inside gland tube such as the cancer cell when the gland lump occurrence cancer change, "home position cancer" call, be cancer cell invade proper film then be called "cancer inside the mucosa".Because of nonentity inside the mucosa lymphoid tube, past cancer inside the mucosa and home position cancer's being similar will not take place a lymphoid way to transfer, so all need to go part to cut off a treatment.
Was called "gradually sex cancer change" while wearing a mucosa muscle layer to deeply get into mucosa bottom layer such as the cancer cell when gland lump cancer change.Because the mucosa bottom layer contains abundant lymphoid tube, the for this reason hour contains the possibility that the occurrence transfer.
2.large intestine gland the clinical performance of the lump:Take care of form gland lump to present circular or oval, the surface is smooth or present leaf's form in cent, the color is pink, the quality is solid and often have the Di that thin thick one length doesn't wait to attach to bowel wall up.If the tumor only several sizes, can also present a wide Ji form but have no Di.The floss form tumor mostly presents a wide Ji form and the surface is rough, the color ash is red, and the quality is soft.(like placenta quality)The hybrid sex gland lump can have Di or present a wide Ji form, surface part of smooth part rough.The gland lump cancer can appear to ulcerate or become hard knot when the gland lump cancer change.Symptom and its size of gland lump and place the part be relevant and the small gland lump has no symptom.Because the gland lump grow up, appear of the symptom be the for the purpose of blood the most familiar.But bleed in a little moment, or when the gland lump be located on right half colon, its issue of blood isn't easily realize by the naked eye, just can appear while moving bowels concealed blood to check masculine gender.The floss form gland lump often secretes a more sticky liquid, past can express for sticky liquid then, sticky liquid blood then with the bowels number of times increase.Bigger have Di gland the lump can cause a bowel set to fold but with the result that stomachache.When focus was near apart from the ass, the tumor took off from the ass while can appear move bowels.Drive sometimes the misdiagnosis is for"the internal hemorrhoid take off to hang".
3.large intestine gland the diagnosis of the lump:The hard tube B form colon mirror can check to Be 20 Li rices apart from the ass.Be apart from the ass 20 Li rices above large intestine in of the gland lump is infused a bowel check by barium to discover before.But the barium infuse bowel to leak to diagnose a possibility very big.According to the report way, the fiber bowel mirror checks the diameter one Li rice following polyp of , the barium infuses bowel and can discover among them of 46%, 2 Li rices above polyp barium infuses bowel also have 25% to be leak to diagnose.Therefore now in order to most dependablely check a method, the fiber bowel mirror still has already leaked to diagnose as well of possibility.The bowel mirror discover of the polyp all should live check, small of or have the polyp of Di can give or get an electric shock to slice to take off in addition to sending a pathology check, bigger, the polyp of wide Ji is at the focus center area then, have ulcer or hard knot etc. is suspicious to have a cancer to change area many pliers to take a few organizations to send a pathologic check.There is the gland lump naked eye that the cancer change see can with have no the cancer change of gland lump have no differentiation.But bowel mirror in if see the gland lump surface anomaly, have already ulcerated formation have already fixed feeling, wide Ji or quality by living the focus base of the check pliers push very the frailty often hints to have already had a cancer to change.Move bowels a concealed blood experiment is discover large intestine gland that the meaning of the lump isn't big.Adopt a mirror technique inside the emulation of spiral CT in recent years, carry on an observation to the whole large intestine mucosa, can discover one Li rice following tumor.
