What effect do corticosteroids have on a client undergoing chemotherapy for breast cancer?

Corticosteroids play an important role in the management of patients undergoing chemotherapy, particularly for breast cancer. They can help decrease inflammation and suppress the immune response, which can alleviate some of the adverse side effects associated with chemotherapy. Specifically, corticosteroids can reduce symptoms such as nausea and vomiting, assist in managing pain, and help control allergic reactions that may arise from certain medications used in chemotherapy. These benefits may contribute to an overall improvement in the patient's quality of life during treatment.

Although other effects of corticosteroids can include changes in blood pressure and potential influences on tumor dynamics, the primary function in this context relates to symptom management and supportive care, making the option about decreasing the signs and symptoms of cancer most relevant.
