Green Chemistry in Cancer Care: Towards a Sustainable Future

The confluence of green chemistry principles and oncology is a vital frontier in the creation of sustainable medical practices. This review discusses the ways in which green chemistry will revolutionize cancer therapeutics, ranging from drug design and synthesis to clinical delivery and waste disposal. We discuss new trends such as greener synthetic pathways for chemotherapeutic drugs, green drug delivery systems, and eco-friendly radiopharmaceuticals. The ecological impact of the pharmaceutical sector, especially oncology, calls for immediate incorporation of green chemistry principles. This article collates recent findings on greener anticancer drug synthesis, biodegradable delivery systems, and minimization of waste, and discusses implementation challenges. A framework for incorporating sustainability metrics into cancer drug development pipelines and clinical practice is proposed, highlighting that environmental responsibility and patient care complement each other rather than constitute conflicting priorities.
