Nanotechnolgy has taken the place of big machines. A nano-scale tool that distinguishes soft cancerous cells from stiffer normal ones could save lives by making it easier to diagnose cancer.
Using atomic force microscopes, a team of US scientists showed for the first time that the surface of living cancer cells were more than 70 percent softer than their healthy counterparts.
This method was found successful in finding malignant cells in case of lung, breast and pancreatic cancers.
Currently, pathologists examine surgically-removed tissue by placing stained, thinly-sliced sections on a glass slide and looking at them under a microscope for signs of the disease.
Researchers should be able to diagnose cancerous cells perfectly using this method because sometimes normal cells seems to be malignant.

It's unpossible to trick the nature. We find new solutions and nature makes so that they don't work more. We have to die. Cancer is not the best way, surely, but if it will be the way to avoid it, the nature will create an other .
