The fight against cancer has long been scientists and clinicians to
the direction, but if the cancer can be withstood before the start of
the disease is undoubtedly a better way. According to the World Cancer
Research Fund (WCRF) released new estimates, through healthy diet,
regular exercise and maintaining a healthy weight, every year there
are 620,000 cases in China can prevent cancer, including many common
tumors, such as breast cancer (20% of cases), stomach (33% of cases)
and endometrial cancer (34% of cases) can be prevented. Nature
Magazine March 24 issue of the Journal will introduce the "Outlook:
Cancer Prevention" feature, reported from more than one side of cancer
prevention knowledge. Number of deaths from cancer worldwide each year
about 760 million people, according to the World Health Organization
(WHO) estimates that by 2030, the number of deaths from cancer each
year more than 1,700 people, than they are now double, especially in
Asia and developing countries. Therefore, the anti-cancer and cancer
in the world a continuous and urgent task. Based on current research,
is difficult to have a single effects and drugs to combat cancer, only
to take comprehensive measures, including prevention and early
detection is the most important. In cancer prevention, tobacco
control, lose weight, limit alcohol, proper diet, prevention of
infection, adequate exercise, away from the risk factor is most
important. Since 1971, the United States since the implementation of
national cancer plans, cancer prevention and control has made
remarkable progress. American Cancer Society (ACS) and the National
Cancer Institute (NIH), based on 1991-2006 national statistics, said
in 15 years, the American Cancer mortality by 15.8% -21%, the
incidence rates (new cases ) 1% annual rate of decline (JAMA. 2010;
303 (11), PLos One. 2010; 5 (3): e9584). Summarized in 15 years,
tremendous progress made by the United States cancer, there are
three experiences: First, successful prevention, especially smoking
reduction; Second, early detection, cancer screening are increasingly
common; the third is the improvement of cancer treatment, in
particular, is a palliative treatment. Experience in the three most
critical measure is full of propaganda and education. These, we should
be able to present this is done, and can do better. However, we failed
to do so, but did not do. Deserve our profound reflection and review.
Basic level, environmental pollution, living habits, occupational
hazards, population aging is of course an important reason. However,
some hope that "cancers wealth" of people and things, or a lot of
people. It is worth noting that China and some Asian developing
countries, the incidence of cancer not only reduces the contrary, 2.5%
annual growth rate of malignancy, according to May 2007 the Ministry
of Health statistics, cancer mortality rates of urban and rural
residents increased by 14.7 % and 21.6%. Now, nearly 200 million
people in China each year die from cancer, accounting for about a
quarter of total mortality, and endanger people's lives and health as
"the first killer." Annual costs for cancer treatment in China up to
1000 billion yuan, has seriously hampered the standard of living of
our people and economic development. China and the United States in
the cancer front for the huge gap, can not but cause us to reflect and
anxiety.
