Smart drugs herald cancer breakthrough

From Guardian Unlimited:

"A new generation of targeted drugs that could help women with advanced breast cancer are being developed with the help of nanotechnology.
Scientists have discovered a way of delivering traditional anti-cancer drugs and hormonal drugs simultaneously using soluble compounds which home in on the cancer's blood supply.

For the first time, they have found a way of carrying the drugs directly to the site of the cancer. This promises to give women with metastatic disease, where the cancer has spread to other parts of the body, a better chance of survival. It may also reduce some of the toxic side-effects of treatment. "
