Why cancer is so hard to cure, explained by infographic

In the United States alone, cancer is the second leading cause of death, surpassed only by heart diseases. Although the first records of cancer in humans can be traced back to ancient 5,000-year-old Egyptian scrolls, to this day there is no general cure for cancer. But that’s not out of lack of trying. Each year, billions of dollars are funneled towards research that might one day finally rid humanity of this dreadful disease. There are already many promising new treatments like a potentially universal cancer vaccine or a malaria protein that binds to cancer cells and kills 95% of tumor types.
