I doctor-in nangmah emaw, i hmangaih tak emaw cancer a vei tih a hrilh hian, enkawl dan tur chungchang i sawi dawnin "radiation therapy" tih thumal i hriat hian tlem a hlauthawng leh lungkham deuh hi thil awmdan pangngai a ni. "Radiation" tih thumal kan hriat hian kan rilruah thlalak hlauhawm deuh a lo lang thin. Mahse a nihna takah chuan tunlai technology hmang hian heng enkawlnate hi a changkang hle a, a him hle bawk. Chuvangin vawiin hian radiation therapy hmanraw ber leh hman tlanglawn ber, `External Beam Radiation Therapy` emaw `(EBRT)` emaw chungchang hi han sawi ila. He thuziak i chhiar zawh hunah chuan he thil chungchangah hian i hlauhthawn tawh lo ang a, hriatthiamna chiang tak i nei tawh ang tih ka ring tlat a ni.
A awlsam zawngin, External Beam Radiation Therapy (EBRT) hi eng nge ni?
A awlsam khawp mai. Hei hi cancer dona atana hman thin radiation therapy chi khat ber a ni. Chu chu khum bik leh machine lian takah i mu a, chu chuan cancer-ah radiation beam control dan dik tak a thawn a ni.
A pawimawh ber chu, he machine hian i taksa khawiah mah a tawk lo . Hmun hla tak atangin hna a thawk thin. A dik tak chuan he machine hi cancer cell chauh tichhe thei tura siam a ni a, chutih rualin cell hrisel tak takte tihchhiat tlem thei ang bera siam a ni bawk.
I taksa chhunga cancer cells te hi target tenau tak an ni ang tih han ngaihtuah teh. He EBRT machine hi super sniper ang mai a ni a, chu target chu chiang takin a kap thei a ni. Target chu a chhehvela cell sual lo (hrisel) te tichhe lovin a tichhia a ni.
He enkawlna hian taksa chhungah engtin nge hna a thawh?
He enkawlnaah hian high-energy beam hman a ni. Heng beam te hian cancer cells te that thei tur particle chak tak, charge sang tak tak a siam thei a ni. Beam chi thenkhat chu i taksa chhung thuk takah a kal thei a, cancer cell bakah a bula cell hrisel te pawh a nghawng thei bawk. Mahse doctor-te thil tum ber chu cancer cells chauh target a, tissue hrisel tihchhiatna tihtlem a ni.
Hei atan hian particle chi hrang hrang hman a ni. Eng nge an nih i han thlir teh ang.
| Particle chi hrang hrang hman a ni | Hrilhfiahna awlsam tak |

EBRT treatment tam zawkah chuan `linear accelerator` (LINAC) an tih machine an hmang thin.
EBRT enkawlna hi eng dinhmunah nge hman a nih?
Doctor-te chuan he enkawlna kawng hi thil pawimawh engemaw zat atan an hmang thin.
- Cancer cells te tihchhiat emaw, taksa peng danga a darh loh nan tihtawp emaw.
- Treatment dang adjunct angin. Entirnan, operation hmaa tumor tihtlem emaw, operation emaw chemotherapy emaw hnua cancer cell la awm zawng zawng tihbo vek emaw.
- Symptoms te tihziaawm. A chang chuan, he enkawlna hi natna emaw, harsatna dang emaw thlentu tumor te tihtlem nan leh damlo tan hahdamna pe turin an hmang thin. Hei hi `palliative care` kan ti bawk.
He enkawlna hi hmun bik emaw hmun hrang hranga awm cancer te tan hman a ni ber. Entir nan:
- Breast, colon, lung, prostate, uterine, leh lu leh kawng cancer te a awm thei
- Cancer te chu leukemia leh `Non-Hodgkin lymphoma` te an ni
EBRT enkawlna chi hrang hrang a awm em?
Awle. EBRT hi radiation beam siam dan, a kal dan leh a target dan a zirin enkawlna kawng hrang hrangah then a ni. Hengte hi technical deuh a ni a, mahse awlsam taka i hriatthiam chuan i tan a pui hle ang.

Hei hian a ti na em?
No. Radiation chu i hre lovang. Mahse machine atang chuan "click" emaw whistling emaw ri i hre mai thei. Eng eng (a bik takin thluak enkawlnaah) i hmu thei. Tin, rim mak tak mai pawh i hre thei bawk. Hei hi thil pangngai a ni vek a, a pawi lo.
Eng chen nge enkawl a nih?
I enkawl hun tur chu i cancer chi, a lian leh a awmna hmun a zirin a innghat ang. Enkawlna hi nitin (kar khatah ni nga) kar engemaw zat pek thin a ni. I radiation oncologist chuan i enkawl dan tur leh i enkawl hun chhung chu chiang takin a hrilhfiah ang che.
He enkawlna hian a hlawkna leh a nghawng tha lo awm thei te chu engte nge ni?
Radiation therapy hi kum 100 chuang zet hman a ni tawh a. Tunlaia technology awm tawh nen chuan a him leh dik lo zual sauh sauh a ni. EBRT enkawlna thatna ber chu:
- Cancer cell tihchhiat.
