Половина случаев смерти от рака может быть предупреждена

*American Cancer Society 2005 report estimates half of cancer deaths
preventable*
The newly released annual report of the American Cancer Society entitled
`` Cancer Prevention and Early Detection: Facts and Figures,'' estimates
that healthier lifestyle practices and greater participation in cancer
screening programs could cut deaths from the disease in half. The report
discusses the importance of not smoking, good nutrition, proper weight
maintenance, exercise, sun protection, and utilization of tests such as
mammography, colonoscopy, pap smears and prostate cancer screening.
Deaths from cancer, cardiovascular disease and diabetes currently
account for two-thirds of all mortality in the United States.
According to the report, 570,280 cancer deaths will occur in 2005, with
168,140 caused by tobacco. One-third of the projected deaths will be
caused by poor nutrition, lack of exercise, or being overweight. The
American Cancer Society recommends that people emphasize plant sources
in their diet by consuming five or more servings of vegetables and
fruits each day, and by limiting processed grains and sugars, and red
meat. Alcoholic beverage consumption should be limited. With 65 percent
of American adults classified as overweight or obese, calorie
consumption should be carefully balanced with physical activity.
A large number of projected deaths from cancers of the breast, cervix,
colon and rectum could be prevented if men and women participated in
regular screening for these cancers. Ninety-seven percent of breast
cancer patients diagnosed at the localized stage are alive at five
years, making early detection of the disease critical. Colorectal
cancer, if diagnosed and treated early, has a 90 percent five year
survival rate, yet the failure of the majority of individuals to take
advantage of screening tests for this cancer has resulted in only 39
percent of the cases diagnosed in their early stage. Improved insurance
coverage for colorectal cancer screening procedures is recommended to
increase their use.
The fact that half of the deaths from this major killer could be avoided
is good news, and should encourage better nutrition and greater
participation in cancer screening. While tobacco use continues to
decline, obesity is increasing, making an awareness of proper nutrition
and exercise even more critical.

* Thousands of published scientific findings provide a clear road map as
to what one can do to reduce their risk of developing cancer. The
problem is that people are overwhelmed by the volume of cancer
prevention data and have largely failed to take the necessary steps to
reduce their personal risk.
Cells operate under the direction of genes located in the DNA. Our
existence is dependent on the precise genetic regulation of all cellular
events. Healthy young cells have nearly perfect genes. Aging and
environmental factors cause genes to mutate, resulting in cellular
metabolic disorder. Gene mutations can turn healthy cells into malignant
cells. As gene mutations accumulate, the risk of cancer sharply increases.
Human studies show that about 70% of gene mutations are environmental
and, thus, relatively controllable based on what we eat, whether we
smoke, or exposure to genotoxins or radiation (Ljungquist et al. 1995;
Herskind et al. 1996; Finch et al. 1997). Antioxidant supplements have
become popular because they reduce gene damage inflicted by free
radicals. However, it takes more than antioxidants to adequately protect
genes against environmental mutation.
The first line of defense against the many carcinogens in the human diet
are agents that prevent gene mutation. Many antimutagenic agents have
been identified in fruits and vegetables, the most potent being the
indole-3-carbinols, the chlorophylls, and chlorophyllin (Negishi et al.
1997). The traditional dietary antioxidants should be considered only as
a secondary line of defense against cancer because it is more important
to inactivate or neutralize carcinogens in the first place than to try
to protect the cells and proteins downstream from their effects.
