Cancer cells need a lot of nutrition to multiply, but they don’t produce their own nutrients, according to lead researcher Nie Guangjun of China’s National Center for Nanoscience and Technology (NCNST). All the blood, oxygen and energy are conveyed to the cancer cells through blood vessels, so many scientists are trying to block the blood vessels that are feeding the tumor. Read more.
