Zoo li ntau yam "scout," nws tuaj yeem tswj tau ntau yam xwm txheej nyuaj-los ntawm cov khoom tsis txaus ntseeg mus rau microcalcifications, los ntawm cov hlwv mus rau qhov hloov pauv hloov pauv- kos duab "panoramic scan" ntawm lub mis noj qab haus huv.

Ua ntej, thiab feem ntau, yog tusKev soj ntsuam zoo ntawm cov chaw kho mob lossis imagiologically kuaj pom qhov tsis txaus ntseeg.

Kev coj los ntawm ultrasound, tus kws kho mob siv cov koob txhaj tshuaj tseem ceeb (feem ntau yog 14G lossis 16G) coj cov ntaub so ntswg los ntawm ntau qhov chaw ntawm qhov loj. Qhov no lees paub qhov kev kuaj mob thiab muab lub hauv paus rau kev npaj phais tom ntej (lumpectomy vs. mastectomy) lossis tshuaj kho neoadjuvant.

Thib ob, raumicrocalcifications kuaj pom ntawm mammography, rab koob biopsy yog ib qho cuab yeej tseem ceeb. Cov calcifications no feem ntau yog tib qho kev qhia rau Ductal Carcinoma In Situ (DCIS) lossis mob qog noj ntshav thaum ntxov. Vim tias lawv me me dhau los ua palpate lossis qhia meej meej ntawm ultrasound, tus kws kho mob yuav tsum siv cov kab mob stereotactic biopsy. Ntawm no, "biopsy" txhais tau tias siv ib sab tshwj xeeb -noj koob, coj los ntawm 3D kev tswj xyuas, kom meej "tom" thaj chaw calcified thiab rho tawm cov qauv. Qhov no zoo heev txhim kho qhov kev kuaj pom tus mob qog noj ntshav thaum ntxov, ua tiav "kev tshawb pom ntxov, kuaj pom ntxov."

Tsis tas li ntawd, koob tshuaj biopsy ua lub luag haujlwm tseem ceeb hauv kev tswj hwmcomplex cysts. Cov hlwv yooj yim uas daws tau raws li qhov xav tau yog qhov zoo, tab sis rau cov kab mob nyuaj nrog cov phab ntsa tuab, septations, lossis cov khoom sib xyaw ua ke, qhov yooj yim aspiration yuav tsis txaus. Doctors may use a vacuum-assisted biopsy needle to first evacuate the fluid, then cut and retrieve tissue from the cyst wall for pathological examination to rule out intracystic carcinoma.

Rau cov kab mob uas tsis tuaj yeem kuaj pom ntawm qhov kev kuaj mob tab sis muaj qhov tsis txaus ntseeg ntawm kev kuaj pom, cov koob tshuaj biopsy tuaj yeem siv ua ke nrog cov xaim hauv zos. Nyob rau hauv cov duab qhia, ib tug hooked localization hlau yog muab tso rau ntawm lub biopsy koob ncaj qha mus rau hauv lub qhov txhab, tom qab uas phais excision raws li nram no. Qhov no ua kom tus kws phais tuaj yeem pom tseeb thiab tshem tawm lub hom phiaj qhov txhab thaum khaws cov ntaub so ntswg ntau li ntau tau.

Thaum kawg, kev siv cov koob tshuaj biopsy txuas mus raukev tshuaj xyuas thiab kev tshawb fawb. Rau cov neeg mob uas tau txais kev kho mob neoadjuvant, ua ntej- thiab tom qab- kev kho mob biopsies tuaj yeem soj ntsuam cov qog cov lus teb rau cov tshuaj, qhia seb puas xav tau kev hloov pauv. Nyob rau hauv kev tshawb fawb pem hauv ntej, cov ntaub so ntswg nyob tau los ntawm biopsy yuav siv tau rau cov noob qhia profileing thiab tshuaj rhiab heev soj ntsuam, paving txoj kev rau cov hom phiaj tshiab tshuaj thiab kev kho tus kheej tiag tiag.

Yog li, lwm zaus koj hnov ​​​​cov lus nug "dab tsi yog biopsy?", nco ntsoov: nws tau ntev dhau los ntawm "kev kuaj mob qog noj ntshav." Nws yog ib qho cuab yeej siv dav siv thoob plaws tag nrho cov kab mob ntawm lub mis txuas ntxiv - kuaj mob, kho, saib xyuas, thiab tshawb fawb.
