Causes of cancer..
« on: October 12, 2012, 12:20:34 AM »
Although the exact cause of cancer is unknown there are various things which might put you at risk.
For example, we cannot live without oxygen, that’s for sure.
But did you know that oxygen, in its free radical form can be the main reason behind development of cancer cells?
Free radicals are atoms or groups of atoms with unpaired electrons which may be highly reactive.
As we grow older or are exposed to certain conditions, the rate of production of these oxygen free radicals increases while
 the ability of the body’s immune system to fight the ‘oxidative damage’ caused by these free radicals goes on decreasing.
When a lot of these oxygen free radicals accumulate over a period of time, it causes changes in the DNA of cells causing
cancerous changes in them.This results in normal cells turning into cancerous ones.
