Vickers said, "The label 'unproven' is inappropriate for these types of therapies; it really is time to say that a lot of alternative most cancers therapies have been 'disproven'."[204]
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。
另一方面，現在有些方法則是想利用身體本身的免疫系統產生非專一性的免疫反應來對抗癌細胞，例如卡介苗膀胱內灌注免疫療法（英语：intravesical BCG immunotherapy）將卡介苗灌注進入膀胱內，以引發免疫反應對抗表淺性膀胱癌（英语：superficial bladder most cancers）。此外使用干擾素和介白質素，均可引起免疫反應。而使用疫苗所產生的免疫反應來對抗腫瘤的研究也正在進行當中，尤其是針對惡性黑色素瘤與腎細胞腫瘤（英语：renal cell carcinoma））。
確診為癌症後就要進一步做癌症屬於哪一期之分期檢查，觀察是否有轉移，並定期追蹤以免癌症復發，以便醫師擬定治療方向。（延伸閱讀：癌症診斷的目的與方法）

Diminished expression of DNA repair genes disrupts DNA fix. This really is demonstrated during the determine in the 4th degree with the top. (Within the figure, crimson wording suggests the central position of DNA problems and defects in DNA maintenance in the progression to cancer.) When DNA restore is deficient DNA injury stays in cells at an increased than standard amount (5th stage) and results in amplified frequencies of mutation and/or epimutation (sixth degree).
A further mutation from the signaling equipment on the mobile may well mail error-producing indicators to close by cells.
物理致癌物，例如紫外线和电离辐射；而异物刺激、创伤、慢性炎症等会促进恶变进程。
身体的化学变化。癌症会打乱您体内正常的化学平衡，增加出现严重并发症的风险。化学失衡的体征和症状可能包括过度口渴、尿频、便秘和意识混乱。
