Detailed Notes on 癌症

某些癌症类型,如睾丸精原细胞瘤以及不同类型的儿童白血病和淋巴瘤,如果加以适当的治疗,即使癌细胞已经扩散到身体其它部位,治愈率也很高。

放射治疗即常说的放疗,根据其治疗方式及适应证可分为根治性放疗、姑息性 放疗和联合治疗,具体内容可参考百度百科及百度药典,在此不过多介绍。但需要 注意,放疗并不一定能完全治疗癌症,且在治疗过程中会出现诸多不良反应,如 乏力、恶心、厌食、皮肤痒肿、口咽疼痛、局部毛发脱落、神经损伤、心肺功能 异常(如干咳、气喘等)、胃肠功能紊乱(如恶心、呕吐、体重下降等)等。

允许其快速增长。基因突变可以命令细胞快速增长和分裂。这将产生许多具有相同突变的新细胞。

癌症是全球排在第二位的死亡原因。不过,随着癌症筛查、治疗和预防的改进,多种癌症的生存率有所提高。

如果发现早,癌症更有可能对治疗做出反应,从而大大提高存活概率,同时降低发病率和治疗费用。通过早期发现癌症和避免延误治疗,可大大改善癌症患者的生活。

筛查旨在确认尚未出现症状但已具有暗示特定癌症或癌症前期迹象的个体。如在筛查中发现异常,则应进行进一步检测以作出明确诊断,如果证明存在癌症,还应转诊进行治疗。

放射治療可用來治療發生在各個部位的固态瘤,包括腦、乳房、子宮頸、咽喉、肺、胰、前列腺、皮膚、胃、子宮或軟組織的肉瘤,治療白血病和淋巴瘤有時也會使用輻射。放射治療所使用的輻射劑量取決於多項因素,例如癌症種類以及是否有可能破壞週遭組織和器官。如同其他的治療方式,放射治療仍然有其副作用存在。

Experimental cancer solutions are studied in medical trials to check the proposed treatment to the ideal current remedy.

微量營養素缺乏被認為與癌症有關,但是進行隨機臨床實驗需要眾多人數參與,需時多年才能完成,因此花費也極為昂貴和複雜,所以很少實施。而通常只能以單劑量來做實驗,缺乏其他濃度比較,使得難以評估實際臨床所需的量也是一大問題。
