The 2-Minute Rule for 癌症
中医主要用于治疗晚期癌症,包括肺癌、胃癌、肝癌、结直肠癌、乳腺癌、淋巴瘤、食管癌、鼻咽癌等,有时还可联合化疗或放疗,以缓解不良反应,提高疗效。如果篩檢為陽性,或者是出現許多前述症狀、久未改善,就需進一步診斷,癌症診斷方式包括三大類:

Try and location People sweet barn owls, or Individuals iconic vultures. You can find even some incredibly amazing birds with a few pretty legendary Appears, such as the Kookaburra!
放射線治療(也稱放療、輻射療法)是使用輻射線殺死癌細胞,縮小腫瘤。放射治療可經由體外放射治療(英语:external beam radiotherapy)或體內近接放射治療。由於癌細胞的生長和分裂都較正常細胞快,藉由輻射線破壞細胞的遺傳物質,可阻止細胞生長或分裂,進而控制癌細胞的生長。不過放射治療的效果僅能侷限在接受照射的區域內。放射治療的目標則是要儘可能的破壞所有癌細胞,同時盡量減少對鄰近健康組織影響。雖然輻射線照射對癌細胞和正常細胞都會造成損傷,但大多數正常細胞可從放射治療的傷害中恢復。因此通常在臨床上,醫師與放射專家會小心計算需要的放射線劑量,同時放射治療也會分成許多次進行,讓健康的組織在每次輻射線照射的間隔中能有機會恢復。
