"Radiation" tih thumal hian a ti hlauhawm deuh mai thei. A bik takin cancer enkawlna chungchangah chuan chu hlauhna chu a nasa zawk thei a ni. Mahse tunlai hian technology hian hma a sawn nasa hle. Tun hma ang lo takin tunah chuan heng enkawlnate hi chiang tak leh uluk takin tih theih a ni tawh. Chuvangin vawiin hian cancer enkawlna atana radiation hmanga enkawlna hman tlanglawn ber, External Beam Radiation Therapy, a tawi zawngin EBRT kan sawi dawn a ni.
A awlsam zawngin EBRT chu eng nge ni?
Khum chungah nuam takin i mu ang tih han ngaihtuah teh. I taksa khawih lovin, hla takah machine lian tak chuan radiation beam, a design dik tak tak, i taksa chhunga tumor awmte chauh a kap chhuak a ni. Chu chu EBRT kan tih mai mai chu a ni.
Hei hian cancer cell tihchhiat nan high-energy rays hman a huam a ni. A tum ber chu an chhehvela cell hrisel te tihchhiat tlem a, cancer cell te tihchhiat a ni. Hei hi pawn lam enkawlna a nih avangin i taksa chhungah engmah dah a ni lo.
Hetianga enkawlnaah hian radiation machine hian i taksa a khawih ngai lo. Chu ai chuan medical team chuan machine chu hla tak a\anga cancer cell chauh target turin program-in, a tichhia a ni.
External leh internal radiation therapy hi eng nge a danglamna?
Radiation therapy hi chi hnih ah then theih a ni.
1. External Beam Radiation Therapy (EBRT): Hei hi kan sawi dan tur chu a ni. Taksa pawn lama machine atanga radiation thawn chhuah a ni.
2. Internal Radiation Therapy: Hei hian tumor chhungah emaw, a bulah emaw radioactive device te tak te surgery hmanga dah a ni.
Heng hmanraw pahnih hian cancer cell te chu tichhe mahse, an tih dan erawh a danglam hle.
He enkawlna atan hian eng ang energy rays nge hman?
Radiation chu supercharged particle awmna energy beam a ni. Heng particle te hian cancer cell te tichhe thei thiltihtheihna an nei a. He enkawlna kawnga harsatna lian ber chu cell hrisel tichhe lovin cancer cell chauh tihchhiat hi a ni. Chumi atan chuan particle chi hrang hrang hman a ni.
- Photons (X-rays leh gamma rays): Hengte hi EBRT enkawlna atana hman tam ber an ni. Energy sang tak nei X-ray ang mai an ni. I tissue chhung thuk takah an lut thei a, cancer cells te chu an that thei bawk.
- Protons te chu: 1.1.Chungte chu positive charge nei particle an ni. Chung hmanga enkawlna chu `(Proton Therapy)` an ti a. Hei hi technology thar tak a ni. Heta specialty chu proton beam hian cancer tumor a rawn deng hnuah a piah lam kal lovin a tawp ta a ni. Chuvangin cancer bula awm tissue hrisel tak takte chhiatna hi a tlem hle. Amaherawhchu he inenkawl dan hi khawvelah a la awm vak lo.
- Electron: Hengte hi negative charge nei particle an ni. Photon emaw proton emaw angin an kal thuk thei lo. Chuvangin, taksa chunglama tumor, vun cancer ang chi enkawlna atan an hmang tam ber.
EBRT enkawlna tam zawkah chuan ``Linear Accelerator`` (LINAC) an tih machine hmangin heng particle te hi a ti chak a, cancer cell-ah a thlen thin.
EBRT enkawlna chi hrang hrang a awm em?
Ni e, technology hmasawnna avang hian tunah chuan EBRT enkawlna kawng hrang hrang leh chi hrang hrang a awm ta. I cancer awm dan leh a awmna hmun a zirin i doctor chuan i tana tha ber tur a thlang ang.

| Stereotactic Radiosurgery (eg Gamma Knife) hmanga tih a ni. | Hei hi "surgery" tia sawi ni mahse, surgery a ni lo. Thluaka tumor te tak te, shot khat emaw, shot tam tak emaw hmanga radiation dose sang tak tak, chiang taka pek dan a ni. |
| Stereotactic Taksa Radiation Therapy (SBRT) hmanga enkawl a ni. | Hei hi a chunga kan sawi tawh ang chiah kha a ni a, mahse thluak pawn lama awm cancer tan chuan hman a ni a, a bik takin lung, thin leh ruhro ang chi hmunah te hman a ni. |
| Intraoperative Radiation (IORT) hmanga tih a ni. | Hei hi cancer lakchhuahna tur surgery neih laiin tih a ni. Cancer chhunga operation hmanga lak chhuah kim theih loh hmunte chu a rualin radiation pek a ni. |
EBRT enkawlna hi eng ang case nge hman?
He enkawlna hi thil pawimawh engemaw zat atan hman a ni.
- Cancer cell tihchhiat nan: EBRT hi cancer chi hrang hrang enkawlna bulpui atan hman a ni.
- Enkawlna dang thlawp turin: Operation hmaa tumor tihtlem nan (neo-adjuvant therapy) emaw, operation hnua cancer cell awm nia rinhlelh zawng zawng tihchhiat nan leh cancer lo kir leh tur venna atan emaw hman a ni (adjuvant therapy).

- Lu leh kawng cancer a ni
- Thisen cancer te, leukemia leh lymphoma te
Enkawl hma hian eng nge thleng thin? (Planning phase) 1.1.
He planning phase, ``simulation'' tia hriat bawk hi EBRT enkawlna hlawhtlinna atana pawimawh tak a ni. I enkawlna hmasa ber atan engkim buatsaih vek a ngai a ni.
1. Hmun hrang hranga awm dan: .He ruahmanna ni hian khumah i ding ang a, enkawlna i neih lai ang bawkin.
2. Scans: Tichuan, CT, MRI, PET scan hmangin i cancer leh a chhehvela taksa peng hrisel tak takte thlalak dik tak hmuh theih a ni. Hei hian cancer lian leh te, a pianzia leh a awmna dik tak hriat theihna tura puitu a ni.
3. Marking: A dawtah chuan i vunah hian i vunah chhinchhiahna te tak te, dot ang chi tlemte siam a ni ang a, chu chu pen hmangin enkawl tur hmun hriat theih a ni ang. Chungte chu enkawlna hun tawp thlengin a hmunah dah tur a ni.
4. Mold/Mask siam: Enkawl laiin i ding reng theih nan i taksa peng hrang hrang nena inmil tur special mould emaw mask emaw siam theih a ni.
He information hmang hian i medical team te hian ni engemaw zat chhung chu i tan bik treatment plan siam nan an hmang ang.
Enkawl lai hian eng nge thleng?
Enkawl chhungin natna engmah i hre lovang.
Simulation neih lai khan i position ang chiah khan i awm ang. A tul chuan mask bik emaw splint emaw pek i ni ang. Tichuan radiation therapist chuan room a chhuahsan ang a, machine chu a on ang. Mahse , monitor hmangin an en che a , intercom hmangin an biak thei che a ni .
Machine chu i chhehvelah a inher a, aw hrang hrang a siam a, hmun bik takah radiation a focus bawk. I tih tur chu muangchangin, ngawi rengin, thawk pangngaia thawk chhuah mai a ni. Enkawlna zawng zawng hi minute 15-30 vel a ni thei. Mahse, a takah chuan radiation hi minute tlemte chauh hman a ni.
Side effects awm fo chu engte nge ni?
Cell hriselte tihchhiatna chu a theih ang anga tihtlem tum mah ila, chhiatna engemaw zat ven chu a harsa hle. Heng cell hrisel tak takte tihchhiatna hian side effect a thlen a ni.
Pawimawh tak chu heng side effects te hi mi zawng zawng tan a inang vek lo . Tin, taksa peng pakhat radiation hmanga enkawl danah pawh an innghat bawk. Entirnan, lu thlenga enkawltu tu emaw chuan sam a tlakchham thei a, mahse pum enkawltu tu emaw chuan a sam a tla lo thei.
Side effect langsar tak tak hmuh theih thenkhat chu:
- Chau lutuk tih hriat (Fatigue): Hei hi side effect awm tam ber a ni.
- Nausea leh luak chhuak
- Chaw chakna
- Enkawlna hmuna vun a sen, a vawt emaw, a hring emaw
- Enkawlna hmunah sam tlakchham
- Kawng leh kawr enkawl a nih chuan ei harsa
- Lu na
Heng side effect tam zawk hi enkawlna a tawp hnu kar tlemte chhungin a reh zauh zauh thin. I doctor nen hian side effect bik i tawn theih dan tur leh i enkawl dan tur te chu zalen takin sawipui rawh.Side effect eng emaw a nasat emaw, thil danglam tak i hriat emaw chuan i doctor emaw, treatment center emaw hnenah hriattir nghal rawh. A nasat chuan damdawi in Emergency Treatment Unit (ETU) pan a pawimawh.
Take-Home Thuchah a ni
- EBRT hi tunlai cancer enkawlna hmanraw hman tlanglawn tak, natna nei lo leh target sang tak nei a ni.
- Hei hi specialist doctor team-in an ti a ni. A tum ber chu cancer cell chauh tihchhiat a, cell hriselte humhim a ni.
- Side effect hi a awm fo thin a, mahse a tlangpuiin hun rei lote chhung atan a ni. Side effect chi hrang hrang awm dan chu taksa enkawl mek hmun a zirin a innghat a ni.
- I doctor nen hian a enkawlna te, a side effects te, emaw i hlauhthawn leh i ngaihtuahna te chu zalen tak leh rinawm taka inbiakna neih a pawimawh hle.
