Immunotherapy side effects occur because the treatment activates the immune system to recognize and attack cancer cells, which can sometimes lead to the unintended targeting of healthy tissues. Cochise Oncology provides comprehensive monitoring to ensure these reactions are managed effectively, as the presence of side effects does not mean the treatment is failing. Most adverse effects are mild to moderate and can be successfully addressed through personalized care plans and early intervention.
