Do you know that whatever we do or eat these days can cause cancer? Excessive exposure to sunlight increases the risk of skin cancer. Smoking and secondary smoke are the main causes of lung cancer. Radiation, charcoal, vapors, too much fat in our diet, saccharin and many other chemicals found in herbicides and pesticides are known as carcinogens means those things that increase our risk of developing cancer. Pollution in water, soil, air all contribute to the risk of cancer. Are we not becoming more and more afraid of our environment? Our bodies face exposure to far more chemicals than any previous generation’s did. And what is the common denominator all of these carcinogens have? They all increase oxidative stress and oxidative stress is the root cause of all the cancer. Many researchers have offered their theories of cancer development. But, no theory has been able to explain the completely diverse aspects of cancer and the development of the disease within the human body. Dr. Peter Kovacic research supports that when excessive free radicals are allowed to exist near the nucleus of the cell, significant damage to the DNA of the cell occurs. The DNA of the nucleus is especially vulnerable when a cell is dividing, during which time the DNA strand is literally unwound & stretched out. Researchers are now able to confirm not only that free radicals can damage the DNA nucleus but also strands of DNA they damage more frequently.
When met with an onslaught of carcinogens, the body’s repair system gets busy trying to repair the damaged DNA, but during heavy oxidative stress, free radical damage overwhelms the repair system and can lead to mutation of the DNA. Free radicals can also wreak damage on the genetic structure of the DNA, thus leading to abnormal growth of the cell. As these cells continue to replicate, this mutated DNA is carried to each newly developed cell. When there is further oxidative stress to this mutated DNA of the cell, more damage occurs. The cell will then begin to grow out of control and take on a life of its own. It develops the ability to spread from one part of the body to another (metastasis), thus becoming a true cancer.
