Scientists announce world's most sensitive cancer test
... cancerous. Cancer cells tend to de-differentiate, losing the special characteristics of the organ where they started life. Because of this, they no longer need the rigid cytoskeleton which holds them in shape, making them stretchier than normal cells.

...reased usage of vitamin E, and they are at risk of losing its protective effects. The interaction of vitamin C and E is another part of the puzzle, the scientists said. "Both vitamins C and E are antioxidants with related roles, but vitamin C is water soluble and vitamin E is fat soluble," Traber said.
