Aliyense amadziwa kuti kusuta kumawononga thanzi lanu.Ngati mufunsa bwinobwino, n’chifukwa chiyani ndudu zili zovulaza thanzi lanu?Ndikukhulupirira kuti anthu ambiri angaganize kuti ndi "chikonga" cha ndudu.Pakumvetsetsa kwathu, "chikonga" sichimangovulaza thanzi la munthu, komanso carcinogenic.Koma kafukufuku wa Rutgers University ku New Jersey akuwoneka kuti akugwetsa lingaliro lakuti "chikonga" chimayambitsa khansa.

Kodi chikonga mu Ndudu chimayambitsa khansa?

Nicotine ndiye chigawo chachikulu cha ndudu ndipo amalembedwa ngati carcinogen ndi akatswiri ambiri a oncologist.Komabe, palibe chikonga pamndandanda wazinthu zoyambitsa khansa zofalitsidwa ndi World Health Organisation.

Chikonga sichimayambitsa khansa.Kodi kusuta kumawononga thanzi ndi "chinyengo chachikulu"?

Popeza kuti Rutgers University ku New Jersey ndi World Health Organization sananene momvekera bwino kuti “chikonga” chimayambitsa kansa, kodi sizoona kuti “kusuta kumavulaza thupi”?

Ayi konse.Ngakhale kuti zikunenedwa kuti chikonga mu ndudu sichidzachititsa mwachindunji osuta kudwala kansa, kupuma kwanthaŵi yaitali kwa chikonga chochuluka kudzatsogolera ku mtundu wa “kudalira” ndi kumwerekera kwa kusuta, kumene m’kupita kwanthaŵi kudzawonjezera ngozi ya kansa.

Malinga ndi mndandanda wa ndudu za ndudu, chikonga sichinthu chokhacho mu ndudu.Ndudu zimakhalanso ndi phula, benzopyrene ndi zinthu zina, komanso carbon monoxide, nitrite ndi zinthu zina zomwe zimapangidwa pambuyo poyatsa ndudu, zomwe zidzawonjezera chiopsezo cha khansa.

· Mpweya wa carbon monoxide

Ngakhale kuti mpweya wa carbon monoxide mu ndudu suyambitsa khansa mwachindunji, kumwa mpweya wambiri wa carbon monoxide kungayambitse poizoni wa anthu.Chifukwa carbon monoxide idzawononga kufalitsa kwa okosijeni ndi magazi, zomwe zimatsogolera ku zochitika za hypoxia m'thupi la munthu;Kuphatikiza apo, iphatikiza ndi hemoglobin m'magazi, zomwe zimapangitsa kuti pakhale zizindikiro zapoizoni.

Kukoka mpweya wochuluka wa carbon monoxide kumawonjezera cholesterol m'thupi.Kuchuluka kwa cholesterol kumawonjezera chiopsezo cha atherosulinosis ndikuyambitsa matenda amtima.

· Benzopyrene

World Health Organisation imatchula benzopyrene ngati carcinogen ya kalasi I.Kudya kwanthawi yayitali kwa benzopyrene kungayambitse kuwonongeka kwa mapapo ndikuwonjezera chiopsezo cha khansa ya m'mapapo.

· Tar

Ndudu imodzi imakhala ndi 6-8 mg ya phula.Tar ili ndi carcinogenicity.Kudya phula kwanthawi yayitali kumatha kuwononga mapapu, kumakhudza magwiridwe antchito am'mapapo ndikuwonjezera chiopsezo cha khansa ya m'mapapo.

· Nitrous acid

Ndudu zimatulutsa kuchuluka kwa nitrous acid ikayatsidwa.Komabe, nitrite yakhala ikudziwika ngati kalasi I carcinogen ndi ndani.Kudya kwanthawi yayitali kwa nitrite kumatha kusokoneza thanzi ndikuwonjezera chiopsezo cha khansa.

Kuchokera pamwambapa, tikudziwa kuti ngakhale chikonga sichimayambitsa khansa mwachindunji, kusuta fodya kwa nthawi yaitali kumawonjezera chiopsezo cha khansa.Choncho, kusuta kumawononga thanzi ndipo si "chinyengo chachikulu".

M'moyo, anthu ambiri amakhulupirira kuti "kusuta = khansa".Kusuta fodya kwa nthawi yayitali kumawonjezera chiopsezo cha khansa ya m'mapapo, pamene osasuta sangadwale khansa ya m'mapapo.Izi sizili choncho.Anthu omwe sasuta sizitanthauza kuti sadzakhala ndi khansa ya m'mapapo, koma chiopsezo cha khansa ya m'mapapo ndi chochepa kwambiri kuposa cha osuta.

Ndani ali ndi mwayi wodwala khansa ya m'mapapo poyerekeza ndi osasuta?

Malinga ndi ziwerengero za International Cancer Research Institute of the World Health Organisation, mu 2020 mokha, panali milandu pafupifupi 820000 ya khansa ya m'mapapo ku China.Bungwe la British Cancer Research Institute linapeza kuti chiopsezo cha khansa ya m'mapapo chinawonjezeka ndi 25% kwa anthu omwe amasuta nthawi zonse, ndi 0.3% okha kwa osasuta.

Ndiye kwa osuta, kodi khansa ya m'mapapo ikupita bwanji pang'onopang'ono?

Tidzangoyika zaka za osuta: zaka 1-2 za kusuta;Kusuta kwa zaka 3-10;Kusuta kwa zaka zoposa 10.

01 zaka kusuta 1 ~ 2 zaka

Ngati mumasuta kwa zaka ziwiri, timadontho tating'ono takuda timawonekera pang'onopang'ono m'mapapu a osuta.Iwo makamaka amayamba ndi zoipa zinthu ndudu adsorbed m'mapapo, koma mapapo akadali wathanzi pa nthawi ino.Malingana ngati mwasiya kusuta panthawi yake, kuwonongeka kwa mapapo kungasinthe.

02 zaka kusuta 3 ~ 10 zaka

Pamene timadontho tating'ono takuda tiwoneka m'mapapu, ngati simungathe kusiya kusuta panthawi yake, zinthu zovulaza mu ndudu zidzapitiriza "kuukira" mapapu, kupangitsa kuti madontho akuda ochulukirapo kuzungulira mapapu awonekere m'mapepala.Panthawiyi, mapapu awonongeka pang'onopang'ono ndi zinthu zovulaza ndipo anataya mphamvu.Panthawi imeneyi, ntchito ya m'mapapo ya anthu osuta fodya idzachepa pang'onopang'ono.

Mukasiya kusuta panthawiyi, mapapo anu sangathe kubwerera ku maonekedwe awo oyambirira athanzi.Koma mukhoza kusiya kulola kuti mapapo aipire.

03 kusuta kwa zaka zoposa 10

Pambuyo pa kusuta fodya kwa zaka khumi kapena kuposerapo, "Congratulations" zasintha kuchokera ku mapapo ofiira ndi odzaza ndi "black carbon mapapo", omwe ataya mphamvu zake.Pakhoza kukhala chifuwa, dyspnea ndi zizindikiro zina nthawi wamba, ndipo chiopsezo chokhala ndi khansa ya m'mapapo chimakhala chambiri kuposa cha osasuta.

Panthawi imodzimodziyo, iye Jie, wophunzira wa Chinese Academy of Sciences ndi Purezidenti wa Chipatala cha Cancer cha Chinese Academy of Medical Sciences, adanenapo kuti kusuta fodya kwa nthawi yaitali sikungowonjezera chiopsezo cha khansa ya m'mapapo, komanso zinthu zovulaza mu ndudu zidzawononga DNA ya munthu ndikuyambitsa kusintha kwa majini, motero kumawonjezera chiopsezo cha khansa ya m'kamwa, khansa ya m'mphuno, khansa ya m'matumbo, khansa ya m'mimba ndi khansa zina.

Kutsiliza: kudzera mu zomwe zili pamwambazi, ndikukhulupirira kuti tikumvetsetsanso za kuvulaza kwa ndudu m'thupi la munthu.Ndikufuna kukumbutsa anthu omwe amakonda kusuta pano kuti kuvulaza kwa ndudu si nthawi yeniyeni, koma kumafunika kuunjika kwa nthawi yaitali.Zaka zambiri za kusuta, m'pamenenso kuvulaza thupi la munthu kumakulirakulira.Choncho, kaamba ka thanzi lawo ndi la mabanja awo, ayenera kusiya kusuta msangamsanga.
