免疫治疗是当前的研究前沿热点内容，我们也专门总结了一篇免疫治疗方法(详见， 放链接)。其目的主要是通过激发、增强患者本身免疫细胞的免疫功能进行控制、 杀灭肿瘤、以及自身的抗癌过程。其部分方法已开始临床应用，但需要注意多数免疫 治疗还不够成熟，且价格相对高昂，绝大多数仍处于研究阶段。
The real key innovation in this article lies in the use of protein cage nanoparticle-based techniques. These units are engineered to hold indicators that entice NK cells directly to the tumor, overcoming on the list of key challenges in cancer immunotherapy: ensuring which the immune cells discover and attack only the most cancers cells without harming healthful tissue.
For some popular cancers, the English organ title is used. By way of example, the commonest sort of breast most cancers is named ductal carcinoma of your breast.

癌症患者治療和研究的進展限於醫師間各自的研究與測試，直到第二次世界大戰時期，許多醫學研究中心發現同一種疾病在不同國家間的發生率差別相當大，也促使各國的公共衛生組織互相通報疾病及流通醫院治療的資料，直到今日仍然是廣為各國採用。日本醫學界觀察到廣島和長崎原子彈受害者的骨髓完全被毀壞。他們認為放射線可能也可用來治療有問題的骨髓，這項發現開啟了使用骨髓移植治療白血病的想法。
