Nyob rau hauv no tshiab tsim yog ib tug txaus ntshai mob uas tawm tsam tib neeg lub neej. Pob cell yuav tiv thaiv kab mob rau nws tus kheej-tswj Pib ntsais koj teeb muaj nyob nyias. Cov hlwb nkag mus rau cov ntshav, lymph, yog kis tau thoob plaws hauv lub cev mus rau lwm yam kabmob, qhov uas lawv pib mus proliferate thiab metastasize.

Ua rau benign

Cell nyob rau plaub caug-ob teev nws tau thaum lub sij hawm lub sij hawm no arisen, mus nyob thiab tuag. Yog hloov los ntawm tshiab, thiab lub voj voog repeats. Yog hais tias rau ib co yog vim li cas, lub periodicity yog ntxhov, lub cell tsis tuag, thiab tseem loj hlob tuaj, muaj ib tug mob. Qhov no ua rau mob tsim. Ob peb yam tseem ceeb tej zaum yuav pab rau qhov no:

  • Nquag cov pa tshuaj nqus tau pa tej yam tshuaj lom.
  • Tshuaj.
  • Kev haus luam yeeb.
  • Ultraviolet rays.
  • Ionized tawg.
  • Lawm tsis txaus.
  • Nws txo qis kev tiv thaiv.
  • pw tsaug zog ntxaug.
  • Substandard khoom.
  • Khoom uas siv tshuaj raws li nyob rau hauv heev tshuaj lom cawv.
  • Tshee kev nyuaj siab.

cell hloov yog heev tau nyob rau hauv cov neeg pluag tej yam kev mob ib puag ncig, txom nyem noj haus, ua ke nrog kev nyuaj siab.

neoplastic txoj kev loj hlob theem

Muaj ntau ntau theem ntawm lub qog txoj kev loj hlob:

Pib. Cov thawj zaug rau theem ntawm txoj kev loj hlob ntawm cov qog. Rau ntawm no theem, qhov kev hloov nyob rau hauv DNA. Mutated ob noob: ib tug ntawm lawv yog lub luag hauj lwm rau ntawm tes tsis txawj tuag, thiab lub thib ob - rau qhov kev loj hlob. Yog hais tias tus txheej txheem yog tam sim ntawd txais, ob noob ntaub ntawv ib tug phem neoplasm, yog inevitable. Yog hais tias ib tug ntawm cov hloov noob, benign qog tsim.

Promotion. Tshuaj promoters tsis puas cov qauv ntawm cov DNA. Tab sis, nrog ntev-lub sij hawm kev sib cuag nrog lub pib hlwb, muaj yog tau mob loj hlob. Promoters tau ntxias ib tug active cell division. Yog hais tias thaum ntxov mob yog tau kom tsis txhob ib tug mob cancer pathology.

Kev vam meej. Nyob rau hauv kauj ruam kev vam meej mutated hlwb loj hlob nyob rau xob ceev. Qhov no tas ib neoplasm. Rau ntawm no theem, txawm benign qog ua malaise, tshwm sim coj txawv txawv me ntsis ntawm daim tawv nqaij. Yog hais tias koj tsis noj kom raws sij hawm ntsuas, yuav tsim mob cancer. Noob mutate, yuav pib cov txheej txheem ntawm metastasis.

Hom ntawm benign qog

Benign qog - ib tug mob uas muaj ob peb hom.

  • Sarcoma.
  • Nqaij hlav.
  • Teratoma.
  • Choriocarcinoma.
  • Glioma.

Txoj kev rau kev tshem tawm hlav los ntawm tib neeg daim tawv nqaij

Muaj ntau txoj kev uas tshem tawm hlav ntawm daim tawv nqaij. Rau txhua tus neeg mob lag luam xaiv ib lub zuj zus nyob rau hauv lub degree ntawm tus kab mob.

Yuav ua li cas txoj kev yog siv:

Radiowave. Lub lag luam yog ua siv ib tug tshwj xeeb electrode, uas emits ib tug high-zaus yoj. Los ntawm cua sov rau cov qog cia txiav tawm, thaum nws tseem lawm thiab yuav raug xa mus rau kev tsom xam.

Laser. Cov feem nrov txoj kev. Lub teeb pulses, degenerates rau hauv thermal zog, yog vaporized neoplasm. Kev kho mob solders hlab ntsha thiab tiv thaiv los ntshav. Nyob rau hauv cov kev kho mob ntawm kev kawm ntawv kiag li lawm.

Tshuaj. Siv txhoj puab heev tshuaj. Cov qauv no yog siv heev tsis tshua muaj, siv txhoj puab heev acids.

Electrocoagulation. Siv AC los yog high-zaus tam sim no. Lub siab kub txav ntawm daim tawv nqaij tsim. Yog hais tias electrocautery feem ntau tshuav nti, li ntawd, txoj kev yog tsis haum rau siv nyob rau raug daim tawv nqaij thiab lub ntsej muag.

Cryodestruction. Yuav kom tshem tawm neoplasms siv kua nitrogen. Qhov kub ntawm Rho tawm 195 freezes pathology txav lub tsev. Nrog rau qhov no txoj kev nws yog tsis yooj yim sua los tswj ntawm qhov tob ntawm tej yam, thiaj li muaj ib tug uas yuav ua mob rau kev noj qab nyob hlwb los yog nedounichtozhit cov neeg mob.

Phais. Tus txheem ntawm txoj kev ntawm cov pa phais excision nrog ib tug riam phais neeg. Lub disadvantage - lub kev hem thawj ntawm los ntshav, cirrhosis, lub sij hawm ntev ntawm kev ncaj ncees.
