3 Ways Immunotherapy Works Differently from Chemotherapy
Immunotherapy and chemotherapy are both powerful cancer treatments, but they work in completely different ways.
While chemotherapy directly attacks cancer cells using cytotoxic drugs, immunotherapy harnesses the body’s own immune system to recognize and destroy cancer more precisely.
Here are three key ways in which immunotherapy works differently from chemotherapy — and why this matters in modern oncology.
1. Targeting: Chemotherapy Attacks All Rapidly Dividing Cells, Immunotherapy Trains the Immune System
Chemotherapy cannot distinguish between cancer cells and healthy cells that divide quickly — such as those in the hair, digestive tract, or bone marrow. This often causes side effects like hair loss, nausea, and low immunity. Immunotherapy, on the other hand, helps the immune system identify specific cancer cell markers, leading to more targeted and personalized responses.
2. Mechanism: Chemotherapy Kills Cells Directly, Immunotherapy Activates Natural Defense Pathways
Chemotherapy works by disrupting DNA replication or cell division, directly killing tumor cells. Immunotherapy stimulates T-cells, natural killer (NK) cells, and other immune components to recognize and eliminate cancer cells. This approach can create long-lasting immune memory, reducing recurrence risk.
3. Duration and Tolerance: Immunotherapy Aims for Long-Term Immune Control
While chemotherapy’s effects stop once treatment ends, immunotherapy can provide ongoing protection by training the immune system to stay alert. It is generally better tolerated, with side effects often related to immune activation rather than toxicity. However, both require close medical supervision for optimal results.
Integrative Oncology Insight
In integrative oncology, combining conventional treatments like chemotherapy with immune-supportive therapies can create a synergistic effect — enhancing treatment response while minimizing side effects.
Understanding the unique mechanisms of immunotherapy allows patients and doctors to choose more precise and personalized care plans.
