Cancer is one of the proficient evaders of the immune system which claims millions of lives every year. Developing therapeutics against cancer is extremely challenging as cancer involves aberrations in self, most of which are not detected by the immune system. Conventional therapeutics like chemotherapy, radiotherapy are not only toxic but they significantly lower the quality of life. Immunotherapy, which gained momentum in the 20^th century, is emerging as one of the alternatives to the conventional therapies and is relatively less harmful but more costly. This review explores the modern advances in an array of such therapies and try to compare them along with a limited analysis of concerns associated with them.

癌症是免疫系统的熟练逃避者之一，每年夺走数百万人的生命。开发抗癌疗法极具挑战性，因为癌症涉及自身畸变，其中大部分无法被免疫系统检测到。化疗、放疗等传统疗法不仅有毒，而且显着降低生活质量。免疫疗法在²⁰世纪风靡一时，正在成为传统疗法的替代方案之一，其危害相对较小，但成本较高。这篇综述探讨了一系列此类疗法的现代进展，并尝试对它们进行比较，并对与之相关的问题进行有限的分析。
