In the meantime ... silver?
Silver Compounds Found To Be Toxic To Cancer: lab tests have shown that it is as effective as the leading chemotherapy drug - and may have fewer side-effects.
Results from the study at the University of Leeds, published in Dalton Transactions, show that particular silver compounds are as toxic to cancer cells as the platinum-based drug Cisplatin, which is widely used to treat a range of cancers.
The crucial difference is that silver is thought to be much less toxic to healthy human cells, and in some cases, can be beneficial. Silver is currently used for its antiseptic and antibiotic properties, in bandages, wound dressings and water purification filters in the third world.
