Decades of research and billions of dollars, but a cure for cancer has not been found. Why?
Cancer is an unpredictable evolutionary process and tumour cell evolution poses the main problem. A patient can have billions of variety of different cancer cells spread throughout his or her body. We cannot identify all cancer cells that are present in a patient. Cancer cells constantly mutate and evolve. This enables new cancer cells to arise that can evade therapy and cause progressive disease. We cannot know what will evolve. The current cancer theories and approaches are logically inconsistent with the evolutionary nature of cancer.

I think they are celebrating the glass being 1/50th full.
