Eighteen months into clinical trials for new cancer vaccine, world renowned Doctor, Steven Rosenberg from the National Cancer Institute, now has conclusive evidence that our bodies can be made to attack cancer. Working with patients that are terminally ill with the deadly skin cancer melanoma, Dr. Rosenberg has found that 42% of the patients are seeing their cancer disappear.These result more than double previously known response rate for melanoma and give real hope to patients suffering from this disease. Part medical detective story, part real-life drama. Two patients have been their cancer "melt-away", and one is nearly cancer free.
