THURSDAY, Feb. 3 (HealthDay News) -- About 340,000 cancer cases
in the United States could be prevented each year if more Americans
ate a healthy diet, got regular exercise and limited their alcohol
intake, according to the World Cancer Research Fund (WCRF).
These types of lifestyle changes could lead to significant
reductions in particularly common cancers such as breast (38
percent fewer cases per year), stomach (47 percent fewer) and colon
(45 percent fewer).
The research about how a healthy lifestyle can reduce cancer
risk was released Feb. 3 to mark World Cancer Day. The WCRF said
its findings are supported by the World Health Organization's new
Global Recommendations on Physical Activity for Health, a report
that says that regular physical activity can prevent many diseases,
including breast and colon cancer, cardiovascular disease and
"Physical activity is recommended for people of all ages as a means to reduce risks for certain types of cancers and other non-communicable diseases," Dr. Tim Armstrong, of WHO's Department of Chronic Diseases and Health Promotion, said in a WCRF news release.
"In order to improve their health and prevent several diseases, adults should do at least 150 minutes of moderate physical activity throughout the week. This can be achieved by simply walking 30 minutes five times per week or by cycling to work daily," he advised.
Other healthy lifestyle habits that reduce the risk of cancer
include quitting smoking, avoiding secondhand smoke, avoiding
excessive sun exposure, and preventing cancer-causing infections,
the WCRF said.
Cancer is the leading cause of death worldwide. Each year, 12.7
million people are diagnosed with cancer and 7.6 million die from
the disease. But 30 percent to 40 percent of cancers can be
prevented and one-third can be cured through early diagnosis and
treatment, according to the WCRF.
