...Along the way, though, scientists have amassed a wealth of information about how cancer works at the molecular level, from its first awakening in the aberrant DNA of a single cell's nucleus to its rapacious, all-out assault on the body. Armed with that information, they have been developing a broad array of weapons to attack the disease every step along the way. Many of these therapies are just beginning to reach clinical trials and won't be available to save lives for years to come. If you have cancer today, these treatments are likely to come too late...
...Eventually, the goal is to detect precisely which molecular processes have gone wrong in an individual patient's cancer. Rather than being identified as lung cancer or breast cancer or kidney cancer, tumors will be tagged as EGFR positive, for example, or COX-2 positive. "The dream," says M.D. Anderson's Mendelsohn, "is that if Mrs. Smith gets a breast biopsy, we'll be able to say, 'Here are the four genes that are abnormal in her tumor,' pull open a drawer, pick out the antibodies or small molecules designed against the abnormal products of those genes, and give...

...drug had gone into remission with only mild side effects--a little nausea, swelling and diarrhea. In seven of those cases, even the genetic abnormalities known to cause this cancer seemed to have disappeared. Doctors are testing Gleevec on an unusual stomach cancer that is triggered by similar molecular defects...
