Fifty Percent of all Cancers Can Be Prevented.

Researchers  at the Union for International Cancer Control (UICC) World Cancer Congress 2012 stated that 50% of all cancers can be prevented simply by following the steps of what is known in cancer prevention such as:

Don't Smoke.  Smoking causes 1/3 of all cancers.

Lose weight.  Obesity causes 20% of all cancers.

Eat well.    Improvement in diet could reduce cancer incidence by 50% 

Exercise. Increases in physical activity could reduce cancer incidence by as much as 85% in 5 to 20 years.

Eradicating the main viruses associated with cancer worldwide which include human papillomavirus and hepatitis B and C  could lead to a 100% reduction in viral-related cancer incidence in 20 to 40 years.

Screening for colorectal cancer can reduce mortality by 30% to 40%.

Epidemiologists have shown thirty years ago that tobacco, alcohol, diet,  lack of physical activity, and obesity accounted for more than half of all cancer.
