Chemotherapy is one of the most effective treatments for many types of cancer, but it can also weaken the body's immune system. While chemotherapy targets rapidly growing cancer cells, it may also affect healthy cells, including white blood cells that play a crucial role in fighting infections. As a result, people undergoing chemotherapy often become more vulnerable to bacteria, viruses, and other infections.
Although it is not always possible to completely prevent a weakened immune system during chemotherapy, several practical steps can help support immune function, reduce the risk of infections, and improve overall well-being. A combination of proper nutrition, good hygiene, adequate rest, physical activity, and regular medical monitoring can make a significant difference throughout treatment.
