Common tumor among men is reduced by 90% using nanobots

Nanorobots that move through the bloodstream could reduce cancerous tumors in the bladder by 90 percent. In a potential breakthrough, scientists in Barcelona created tiny 450-nanometer-sized robots that deliver therapeutic directly to the growth. Bladder cancer is the one of the common type of cancer in men and while it has a low mortality rate nearly all tumors return within five years. In a study on mice, researchers showed that the tiny machines could eliminate the need for multiple tumor treatments by reducing the tumor after one try. Current treatments for bladder cancer include surgery and chemotherapy, which can cost more than 65,000.
