Free radicals are dangerous
Highly
reactive chemical compounds that can damage DNA and lead to
cancer. They are generated in various ways. For example,
polyunsaturated fats tend to oxidize and thus form free
radicals. A build up of free radicals in a person's system
occurs when the body's own biochemical mechanisms for reducing
their levels cannot keep up with their production and there
becomes an abundance of free radicals in the system. In this
case it is important that the body be supplemented with
antioxidants to finish up the job. Antioxidants block
oxidation and thus free radical formation. Vitamins C and A
are excellent antioxidants and can be taken through
supplemenation as well as a diet high in yellow and orange
fruits and vegetables.

Smoking Causes
30% of All Cancer Deaths
This
makes tobacco smoke the single most lethal carcinogen in the
U.S. Smoking causes more than just lung cancer; it also
causes cancers of the upper respiratory tract, esophagus,
bladder, and pancreas and may also cause cancer of the
stomach, liver, kidney, colon, and rectum. Secondhand smoke
also causes a few thousand deaths from lung cancer among
nonsmokers. Lung cancer survival rate is low because lung
cancer usually goes undetected until it is too late and has
spread. The single most effective way to reduce lung cancer
risk is to quit smoking if you are a smoker and to limit
your exposure to secondhand smoke if you are a nonsmoker.

Cancer Blockers
As Your Diet
Animal (saturated)
fat, and especially that from red meat, is associated with
several different types of cancer, including the colon,
rectum, and prostate. The effect of diet on cancer may have as
much to do with foods that are in a diet as foods that are
not in a diet. Adopting certain dietary habits, such as
reducing dietary fat and eating more soy-based foods, fiber,
fruites, and vegetables, can offer some protection against
cancer because they contain certain properties, such as
antioxidant activity, that act as cancer blockers.
