The term "cancer drug discovery" refers to the process of identifying and developing new drugs that can be used to treat cancer. This involves various stages such as target identification, high-throughput screening, lead optimization, preclinical testing, clinical trials, and regulatory approvals. The goal is to find effective and safe medications that can help control or eliminate cancer cells in patients while minimizing side effects. Cancer drug discovery is an ongoing area of research with the hope of finding new treatments for various types of cancer.
