Cancer treatment is experiencing a significant transformation as immunotherapy gains prominence alongside traditional chemotherapy. Traditionally, chemotherapy has been the cornerstone of cancer care, targeting rapidly dividing cells, including cancer cells. However, it often results in severe side effects such as hair loss, fatigue, and nausea due to its non-selective nature. In contrast, immunotherapy enhances the body's immune response against cancer, leading to fewer side effects and allowing many patients to maintain their daily activities during treatment. The potential for long-term remission is a major breakthrough, particularly for patients with specific tumor characteristics. While the high cost of immunotherapy has been a barrier in India, recent developments in affordable treatment options are expanding access to this innovative care. Both therapies can be complementary, with the choice depending on various factors including cancer type and patient health. This evolution in cancer care offers hope for improved quality of life and treatment outcomes for patients.
