Artemisinin and derivatives like artesunate have been discovered to have cytotoxic effects, inducing apoptosis and reducing metastasis in different types of cancerous cells. Cancer is one of the leading causes of morbidity and mortality worldwide. Additionally, new cases of the disease are expected to rise by 70% over the next 20 years. Clinical trials are underway to explore the potential of artemisinin to treat several different types of cancer: colorectal cancer (Phase 2), bowel cancer (Phase 2), lung cancer (Phase 2), solid tumours (Phase 2), breast cancer (Phase 1) and hepatocelullar carcinoma (Phase 1).
