Wecome to my homepage i hope you enjoy your stay.i like to inform you about alot of intresting stuff in this world.On march 23 2002 my best friend was diganosed with brest cancer...i feel it is my duty to aware young and old people about cancer. Below is just a breif summery i got from web md. April 30, 2003 -- Offspring of a tumor-proof mouse fight off even the most deadly cancers. Now the trick will be to discover their secret. Zeng Cui, MD, PhD, and colleagues at Wake Forest University didn't set out to breed super mice. They were just doing cancer studies in which lab mice are injected with deadly cancer cells. This cancer forms tumors in all known breeds of mice and rats. It always kills them in three or four weeks. Make that almost always. One male mouse didn't die. The researchers tried again. The mouse still didn't die. It "remained healthy and cancer free, and eventually died of old age after a normal lifespan," Cui says in a news release. But before this mighty mouse died, he was bred several times with normal mice. About half the offspring -- just like the original mouse -- couldn't get cancer. When injected with deadly cancer cells, these mice mount an incredibly effective immune response. Their white blood cells swarm the cancer cells and remove them without harming normal cells. White blood cells from these cancer-proof mice can protect normal mice from cancer. Apparently the cancer-proof mice have a genetic mutation that protects them. It's eerily similar to something that happens -- rarely -- in humans. Some people with advanced tumors suddenly have their cancers go away. It's called spontaneous regression. Nobody knows why spontaneous regression happens. Cui and colleagues hope that the mice hold the key. "These observations suggest a previously unrecognized mechanism by which the body can fight off cancer," Cui says. "[The discovery] may have potential for better therapy or prevention of cancer in people." Cui suggests that the secret may also explain why some people never get cancer even though they smoke cigarettes or are exposed to other cancer-causing substances. Cui and colleagues report the findings in the April 29 early edition of the Proceedings of the National Academy of Sciences.
