For many women with breast cancer, tamoxifen, a drug that inhibits the hormone estrogen, can be a lifesaver.
The medicine has been used for decades to fight breast cancers that need estrogen to grow--about 75% of all breast cancers. Unfortunately, breast cancer cells can sometimes become resistant to tamoxifen, a dismal development for patients.

In May 2001, Israeli parents of a nine-year old boy with a crippling disease that left him wheelchair-bound took their child to see doctors in Moscow. In a highly experimental procedure that was presumably unavailable in their home country, those doctors injected fetal stem cells into various regions of his brain.

The nine-year old suffered from ataxia-telangiectasia, a childhood disease that causes degeneration of parts of the brain that control muscle movements and speech. The symptoms include slurred speech, poor balance, impaired immune function, and the appearance of red spider veins called telangiectasias in the eyes, ears or cheeks.
