Brachytherapy mbeu inogona kusara zvachose mumuviri, kana kuiswa kwekanguva kwenguva pfupi.
Mbeu ye-brachytherapy inogona kuva yakakura yehuyo yakasviwa zviyo kana zvishoma zvemutobvu kubva kumichina ipeni. Brachytherapy mbeu inogadzirwa neIodine 125, Palladium 103, Thulium 170, uye Iridium 194 isotopes.
Mhemberero dzeBrachytherapy Mbeu
Brachytherapy - marapirwo emishonga kubva kune mishonga yakaiswa mukati memuviri - inyaya yakabva mukutsvakurudza kwaMarie naPaul Curie.

Mbeu Inouraya Cancer Maselo
Brachytherapy mbeu inorwisa kenza iyo iyo inorarama. Mbeu imwe neimwe inotora ionizing rayation energy. Kana masero emukenza akarongeka akasvibiswa nemirairo, haagoni kukura nekuparadzanisa zvakanaka. Iyo inowedzera simba kubva kumbeu ye brachytherapy inokuvadza kana inouraya kenza yemukenza iri pedo nekuputsa mazita avo emagetsi.
Masero anopa utano achabatwawo nehutachiona hwembeu, asi kazhinji anowanzokwanisa kugadzirisa pachavo uye kuwana hutano hwehupenyu huripo.
Zvishandiso zveBrachytherapy Mbeu
Brachytherapy mbeu inogona kushandiswa kurapa mhando dzakasiyana dzekenza. Chirwere cheprostate chinogona kurapwa ne brachytherapy isingagumi, ichiisa mbeu dzakawanda mumaronda uye ichivabvumira kubvisa miviri kwemavhiki mashoma kana mwedzi kusvikira vasisashandi.
Apo mutumbi une ruvara rwepanyama, yakadai nekenza yehuro, chikadzi, rectum, kana chifuva, chigadziko chembeu ye brachytherapy inogona kuiswa kwenguva pfupi kurapwa. Kenza yepabonde yepabonde inotanga kupera inogona kurapwa nehuwandu hwemadhora (HDR) kusagadzikana kana kubatana kwekemikari. Muzviitiko izvi, catheter dzakanaka kana mabhaloni zvichashandiswa kugadzirisa mbeu ye brachytherapy kwemaminitsi mashomanana apo mushonga umwe neumwe unopiwa.
