臨床實驗,是在癌症病患身上進行新的治療方法的實驗,希望找出更好的方法治療癌症,協助癌症患者恢復健康。臨床實驗測試範圍包含新的治療藥物,新的手術方法或放射治療方式,重新組合不同的療法,或發展全新的療法,如基因療法。

癌症是多种因素长期共同作用引发的基因异常疾病。当机体受到环境中的化学、物理、病毒等致癌物质的影响,和/或因自身遗传、内分泌、性别、年龄等因素的作用时,可发生一系列基因异常改变,形成恶性肿瘤。

The conclusions that end result depend upon cancer's sort and site. Few symptoms are specific. Numerous regularly occur in individuals who have other conditions. Most cancers could be tricky to diagnose and might be viewed as a "terrific imitator".[33]

Cytogenetics and immunohistochemistry are other types of tissue tests. These checks deliver specifics of molecular variations (such as mutations, fusion genes and numerical chromosome changes) and may thus also suggest the prognosis and finest cure.

相較於遺傳性的基因缺陷,生活方式對於癌症的發生並沒有決定性的影響,這是很重要的一個觀念,現今所謂的危險因子,雖然都是經過流行病學的嚴謹分析而得出的結論,但是科學的結論必須要在嚴格的條件控制之下才會成立。雖然抽菸的確會提高罹患肺癌的機率,但直到目前為止,醫學上仍舊無法精確的定義出抽菸的量,或是幾歲開始抽,一定會引起肺癌。每個人在基因上的不同,使得每個人對不同物質的反應都不相同。所以並沒有所謂絕對健康的生活方式,坊間許多生機飲食和眾多號稱防癌的健康食品,所能得到的效果並不大。不需要杞人憂天的飲食及生活,即使是癌症病患,只要保持正常生活,適當補充養分即可。但是有些高危險因子是所有人都應該要小心避免的,例如抽菸、喝酒、進食快餐和嚼檳榔等。

Laser therapy uses superior-depth mild to treat most cancers by shrinking or destroying tumors or precancerous growths.

It is actually utilised to treat basal mobile skin cancer and the very early levels of Other folks like cervical, penile, vaginal, vulvar, and non-smaller mobile lung cancer. It is commonly combined with other remedies, which include operation, chemotherapy, or radiation therapy.

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。

Men and women whatsoever levels of cancer treatment ordinarily receive some sort of palliative care. In some instances, professional medical specialty Qualified businesses endorse that clients and medical professionals respond to most cancers only with palliative care. This applies to sufferers who:[196]

癌症源于正常细胞转变为肿瘤细胞的多阶段过程,通常从癌前病变发展到恶性肿瘤。这些变化是一个人的遗传因素与三种外部因素相互作用的结果,外部因素包括:

肿瘤在其生长过程中,虽然能够暂时通过建立新生血管解决自身给养问题,但是快速的增长一样会将之推向资源和空间匮乏的边缘。隨著腫瘤細胞持續生長,在這樣競爭的壓力下,这时肿瘤就会扩散。而这种肿瘤在生长过程中侵略性不断增加的过程则被称为演进(development)。具体的行为则是生长的加快,并且开始入侵周遭的正常组织(癌症浸润),并且通过血管转移到远端(癌症转移)。

适时输液,补充水分及营养,避免水电解质紊乱、营养不良,尤其是进食不佳者。
