What Is a Cashless Society and How Does It Work?

Greater insight into the causes and mechanisms of cancer has led to better ways to diagnose and treat the many forms of this disease. First of all, advances in detection have improved the ability to discover cancers earlier and to diagnose them more accurately than was the case only a few years ago. (Indeed, some tests can identify precancerous tumours before symptoms appear and thus can be used to prevent cancers from developing.) In addition, improvements in conventional cancer treatments can cure many cases of cancer, and new therapeutic strategies show promise of being even more effective in thwarting the ...(100 of 21846 words)
