Chemotherapy-induced Immunosuppression

Chemotherapy-induced immunosuppression occurs when cancer treatments damage not only cancer cells but also healthy immune system cells, particularly white blood cells that fight infections. This reduction in immune cells weakens the body's ability to defend against bacteria, viruses, and other pathogens, increasing the risk of infections. The suppression can be temporary, lasting weeks or months depending on the therapy, and may require precautions such as avoiding crowded places or sick individuals, and sometimes using medications to boost immune function or prevent infections.
