The Basic Principles Of 癌症

Cancer screening is not really available for many types of cancers. Even though exams are offered, they might not be recommended for everyone. Common screening or mass screening requires screening everyone.

而根據癌症發展的程度,又可分為零、一、二、三、四期等,及早期與晚期,通常零到一期算是早期,但在不同癌症中每期的定義和治療方法都有所不同,確實的分期仍應參考美國癌症聯合委員會的定義。

主要原理是使用高專一性的單株抗體直接結合到腫瘤細胞特有的蛋白質或是細胞激素,影響腫瘤細胞的生長、引起免疫系統反應或是其他功能。已經發展的藥物有針對乳癌的曲妥珠单抗和針對白血病的吉妥单抗在臨床使用。

對於癌症高風險群,例如有家族病史,或是環境汙染(例如輻射屋居民)的人進行基因檢測,可做較深入仔細的檢查分析,服用預防藥物。確定有癌症相關基因突變的人,可藉由預防性的手術,降低癌症機會。

A perfectly-known example of Here is the Philadelphia chromosome, or translocation of chromosomes 9 and 22, which occurs in chronic myelogenous leukemia and ends in manufacture of the BCR-abl fusion protein, an oncogenic tyrosine kinase.

免疫療法是利用人體內的免疫機制來對抗腫瘤細胞。已經有許多對抗癌症的免疫療法在研究中。目前較有進展的就是癌症疫苗療法和單株抗體療法,而免疫細胞療法則是最近這幾年最新發展的治療技術。

Cytogenetics and immunohistochemistry are other kinds of tissue exams. These checks deliver specifics of molecular variations (for instance mutations, fusion genes and numerical chromosome alterations) and will Therefore also indicate the prognosis and finest treatment method.

An additional mutation in the signaling machinery of your cell could deliver mistake-causing 癌症 indicators to close by cells.

癌症的治療無論是化療、手術或放療都是對身體有極大負擔,並且在發生惡性轉移後,無論是何種方式都是很難徹底治癒。所以在癌症的治療仍然是人類面對的極大考驗。在目前對於年老的癌症患者,或許找出能維持生活品質並讓其能平靜走向生命旅程的終點的治療方式,會是比積極消除癌細胞而使用副作用極大的治療方式要來的實際且重要。

癌細胞擴散至距離原始腫瘤遙遠的器官及組織。此時癌細胞流竄於全身,必需借助循環全身的化學治療藥物治療。安寧照護將是治療選項之一。

The phrase emanates from the ancient Greek καρκίνος, that means 'crab' and 'tumor'. Greek medical professionals Hippocrates and Galen, amongst Many others, mentioned the similarity of crabs to some tumors with swollen veins. The phrase was released in English in the modern health-related perception around 1600.[28]

烟草使用、酒精消费、不健康饮食、缺乏身体活动和空气污染是癌症(以及其他非传染性疾病)的危险因素。
