New drugs and therapies are helping breast cancer patients manage the side effects of treatment. For example, Emend is a new drug that effectively controls chemotherapy-induced nausea and vomiting by blocking a chemical substance called 'substance P' that transmits nausea signals. Additionally, Aranesp is a drug for treating chemotherapy-induced anemia, reducing injection frequency, and improving patients' quality of life. Bisphosphonates like Fosamax and Actonel are being studied to prevent osteoporosis caused by chemotherapy. New drugs like Kepivance and Tavocept are also in clinical trials for treating mouth sores and nerve damage, respectively. These new drugs and therapies help alleviate treatment side effects and improve patients' quality of life.
