How to Prevent Environmental Toxins from Damaging Our DNA- by Dr. Richard Firshein

A new area of research targets molecules which are more prone to cause cancer, and natural ways we can help to prevent this. Recent scientific evidence has shown that specific toxins found in cigarette smoke, plastics, diesel, and ultra-violet radiation create damaging lesions within our DNA. The findings published in Chemical Research in Toxicology, provides new insight and understanding as to how environmental agents affect our DNA repair mechanisms; and why certain toxins are so damaging.

The answer at least partly, is due to certain chemicals which contain large difficult to remove molecules, that stick to our DNA.  Examples of these chemicals are those found in automobile exhaust and cigarette smoke ((also known as PAH (polycyclic aromatic hydrocarbons)) which possess the capability to attach to our DNA. Due to the size of their molecules, our bodies struggle to remove said compounds; unlike those of a smaller size which are easily removed.

Most individuals possess a specific repair mechanism-equivalent to a scissor- called NER (Nucleotide Excision Repair). NER is what allows our body to cut out/remove damaged DNA, and replace it with a new copied set of DNA fragments; without the damage or injuries caused by toxins. Conversely, there are some individual who lack the ability of creating such a repair.

One of the advantages of preventive DNA testing, is to understand which patients are at risk for certain cancers; along with which natural compounds are best suited to mitigate this problem. For example, in prostate related cancer it may be tomatoes; which contain both vitamin a and lycopene.

This is one of the various reasons why I incorporate DNA based testing and treatments for most of my patients. It is also the reason I recommend using specific antioxidants, which not only help with DNA repair; but can also halt the subsequent steps once cancer has been initiated.

The good news is, that with time, our bodies remove many of the compounds that damage our immune system at a genetic level. Understanding and determining which healthy compounds work best for individual patients, is where Precision Based Medicine distinguishes itself from traditional medicine; and allows us to provide tailored treatment to each individual patient
