Prostate gland cancer and its analysis
The prostate gland cancer is the old people’s disease, majority of occurrence are in the 60 years old above male old people.
In Europe and the United States etc. region, the incidence rate of prostate gland cancer is the highest, the dwelling place contains the first or the second of male cancer outbreak rate.For example, a think factory in the United States is leading to 12% one 46% towards discovering in the general autopsy of 50 years old above male old people, the outbreak of prostate gland cancer, and is an age is old more, the outbreak rate is high more;Among them, man Jing over 80 years of age exists 2/3 prostate gland cancer.However, in only one small part that appeared clinical symptom while was living, these people’s big part then whole life have no unwell.Statistics according to the expert, the United States the prostate gland cancer clinical outbreak rate in 1981 has the comparison of population total amount in order to have 69 people in 10 myriad peoples each time on the average, death rate then for have 18.8 people in 10 myriad peoples each time;In all cancer death rate, the death rate of the prostate gland cancer has 10% or so.
Prostate gland cancer’s outbreak rate and death rate in China then want to be more obviously low than western countries.Statistics such as 1984 Peking region, the prostate gland cancer leads to 0 in 10 outbreaks in the myriad peoples.75%, is the 1/90 of the United States;Death rate is 0.59%, it is several near in the last yearses to is the 1/1800 of the United States, although our country of the prostate gland cancer be taken bad number have ascension, attain average have in 10 myriad peoples 1.3 people, the United States still than the 50 remaining in height our country is doubly.The reason that hangs extremely a margin to this kind of national outbreak rate in region, still not that clear so far.But can affirm at 1:00, region and race difference had the obvious influence on outbreak rate.For example, together in the United States, black outbreak rate than white man Gao Chu Liang times, compare U.S. citizen Chinese people tall 600%, this hinted to grow to belong to gene to influence the incidence rate of prostate gland cancer.Secondly, the living environment also influences an outbreak circumstance.One Chinese possibility of cancer for living in China from cradle to the grave, suffering from prostate gland is pimping;But he if change residence to the United States to go to, suffered from the possibility of prostate gland cancer to consumedly increase, and is along with settle down horary extension to correspond augmentative.In addition, even if is in the same region, living habitual change, also will influence an outbreak to lead.Japan the prostate gland cancer outbreak rate at first was as just about as China, but about 20 in the last yearses, the living standard continuously raised, the life style gradual west turned, the outbreak of the prostate gland cancer rate also obvious increment, now the outbreak of the Japanese prostate gland cancer the rate have already raised to the 1/10-1/15 of western countries.This is exactly also a warning, these several years to China, our country the people’s living standard also raised a lot, the west turned of the life style have already appeared in some people’s daily life, the outbreak rate of prostate gland cancer probably corresponds an exaltation.According to the statistics in Shanghai City, the outbreak rate of prostate gland cancer compared to increase above 50% in 60’s, and had more quickly augmentative trend now.So, that kind of thought formely the prostate gland cancer didn’t have many standpoints that the toll-gates fastenned with our Chinese have been dated, in the old-age male, the occurrence of the vigilance prostate gland cancer was necessary.
Currently, not explicit to the cause of disease of prostate gland cancer, just discover from various clinical phenomenon top, the growth of change to prostate gland cancer of sex hormone level inside the body relevant fasten.At those because various reason once did a double at teenager’s period side testicle excision, or original double the side testicle develop bad of in the person, always can’t take place a prostate gland cancer.Many prostate gland cancer patient at excision double after the side testicle, descend because of the male hormone in blood level, the tumor can get to obviously repress.The understanding in nowadays BE, the male hormone may stimulate the prostate gland epithelial growth growth, for have already taken place bad change the cell provide material foundation, but it also can’t cause a prostate gland cancer.Real of is what to the cause of disease?Some foods in estimate and food at the output metabolism composition inside the body is relevant.
There being also the problem that a many people concerns moreover is a familiar prostate gland to increase to living in the Chinese or the chronic prostate gland is burning, whether have influence to the occurrence of the prostate gland cancer?Currently, the research concerning this aspect hasn’t got an explicit conclusion.See from the burning disease theory of tumor cause of disease, chronic blaze the incitement of disease may be one of the inducement of cancer occurrence, it can result in the abnormal shape sex variety of organizing the cell.However it’s not clear to, in the prostate gland cancer, blaze the function of disease theory.Our opinion BE, if have burning chronic prostate gland, still early some treatments is good, like this not only can clean burning the disease bring of unwell, also reduce a kind of possibility of to cause of disease vegetable, and why should not be happy to do it?Increase to living to the prostate gland is irrelevant to fasten with prostate gland cancer in learning outbreak, have already had a more research, the opinion is also inconsistent.Someone discovers that increase to get sick a person to win in the prostate gland, outbreak rate and death rate of prostate gland cancer want to compare to have no prostate gland to increase rare person Gao;Organizes in half near prostate gland cancers in, all discover the companion has different degree of increase a born nature change.In the United States, someone discovers to make the prostate gland that the surgical operation cuts off prostate gland to increase to get sick a person to win and there is near quarter making a pathologic checks and discovering that the companion contains prostate gland cancer, therefore put forward prostate gland to increase to living can see as the pathological changes to organize before the cancer, and increase and living process to see as change process before the cancer.But, majority of scholars all oppose this opinion and think that the of these two kinds of pathological changeses doesn’t have obvious relation, they aren’t same either in the occurrence part in the prostate gland.The prostate gland cancer at most takes place after prostate gland a leaf;But prostate gland’s increasing to living then Be taken place to side more leaf and middle period, never occurrence at after leaf.However, also have swollen a kind of cancer that lately lifts a method and is called prostate gland to increase to living an occasional cancer, particularly points in the prostate gland to increase to living and discovers in the surgical operation specimen for these several years.In the western countries, the occasional cancer has prostate gland to increase 8% of getting sick the person one 12%;In the our country, invite at 4% one 6% is or so.The difference of the region isn’t very big.BE increased by the prostate gland non- typical model to living a development to this kind of occasional cancer;Or develop alone, with increased to living don’t relate to?Still not that clear.Probably, the occasional cancer incidence rate and western countries of close by, is reflecting a prostate gland cancer in increasing of China, have to cause a vigilance.Especially those patients who made prostate gland excision, the specimen must send to make a pathology check, the in order to prevent left out prostate gland to increase the diagnosis of livinging the occasional cancer.The prostate gland is a kind of gland organization, prostate gland cancer also with gland cancer most for much see, have 95% around;The having of rest moves to go a skin cancer, scale-like in shape last skin cancer, etc..The prostate gland gland cancer can is divided into a high mark to turn cancer and low mark to turn a cancer two kinds of, the high mark turns cancerous cell to divide better, the malignant degree is lower;The low mark turns a cancer because of the cell and divides badly, the malignant degree is the highest, easy appear to transfer in the earlier period.Usually, the prostate gland cancer in earlier period is all very small and limit after gland body a leaf, there is also no symptom, is a very difficult detection;The later cancer is swollen to appear to knot stanza-like in shape aggrandizement and increase, dispersal’s organization quality in the prostate gland outer circle near pack of film is very strong and tough and sometimes still expand to the whole gland body, and wear to deeply wrap a film, the invasion goes to close by organization organ, or transfers to the lung, liver, and brain…etc. of distance.So, the prostate gland cancer cell is to pass what path transfer?This are alike with other cancers, then directly spread, the lymphoid tube transfer to transfer 3 kinds with blood line.Directly spread to take place first generally, many prostate gland cancer patient because the cancer swollen invasion arrived the seminal vesicles, urine bladder of close by prostate gland, empress urethra etc. organization organ, just arrive hospital to carry on to check treatment while causing symptoms such as homologous blood Jing, blood in urine or row urine difficulty etc..However, lymphoid tube and blood line transfer don’t all not take place as well in the tumor of later period, sometimes the cancer of prostate gland part Be swollen to haven’t infringed upon to wrap a film, the patient also has no of unwell symptom, have already skeleton, lung happened and lock a bone top lymph knot transfering of etc. cancer cooking stove, and have many take place a bone to transfer first.After, when the check looks for an original hair cancer, just discovered a prostate gland cancer.
At clinical up, the doctor usually infringes upon according to the prostate gland cancer of the scope of degree and proliferation, is divided into its four periodses:
Issue 1(A period), take up 10% of the prostate gland cancer around or so.The cancer is swollen to limit at prostate gland of in the organization, clinical up have no symptom, just checking in the corpse or discovering in the pathologic check of prostate gland specimen the cancer is swollen, this kind of cancer becomes more to belong to delitescence, the malignant degree is very low, the patient’s life span with as usual together age person likeness;However, it can also develop other each periods.
Issue 2(B period) takes up 10% of the prostate gland cancer one 15% around.The cancer swollen limits at inside the prostate gland organization, the rectum points check to touch, the B is super or the CT check can also discover, generally have no lymphoid tube to transfer, the serum acidity phosphoric acid Mao isn’t high either.
Issue 3(C period), about 40% prostate gland cancers all belong to Issue 3 while checking.The cancer is swollen have already infringed upon prostate gland to wrap a film outside, partial lymphoid the knot have been already transfered as well, but still have no the distance transfer, the serum acidity phosphoric acid Mao starts increasing Gao.
Issue 4(D period), 40% patients belong to Issue 4.Various checks all confirm that the distance transfers cancer cooking stove, like lung, liver, brain, and bone road…etc., the serum acidity phosphoric acid Mao obviously goes up.
Should point out, the development of each period prostate gland cancer combines not necessarily is press Issue 1 to arrive Issue 4, such a sequence carries on of, can appear the development of jump up type as well as long-term not development.For example, the first period cancer is swollen to stay around Issue 1 over a long period of time as well as directly turn into the third or Issue 4.
This kind of cent expects to is very important in the clinical top, not only relate to cure a project of choice, return have obvious contact with prepare after the quality.Generally speaking, Issue 1 two period patient, as long as cure in time and accommodation, good after preparing, 5 year, the livability can be in above 80%;The third period patient’s five years livability is or so for 60%;And four period though the patient adopts various treatment methods, also only have a livability for 25%5 years.
In fine, the development of prostate gland cancer under the influence of various factor, the difference is very big.In China, this is a kind of disease that is being placed in to rise a stage, the outbreak rate of several near in the last yearses increases to cause the value of the medical boundary very quickly and already.Is a vigilance that the male adult has understanding to this and defend a disease by exaltation to still include a necessity of and fight for discovering to cure in time to is very important in early days.
