normal weight and cancer prevention

Maintaining a healthy weight is the most important thing you can do for cancer prevention. Evidence shows that being overweight puts people at increased risk of cancer and it is is the strongest contributer after smoking.

Advisers for the World Cancer Research Fund (WCRF)recommend that people stay as thin as possible without becoming underweight. Scientists believe that about a third of the most common cancers would be preventable if people ate healthily, were physically active and maintained a healthy weight.
In fact thousands of cases could be prevented each year if people maintained a BMI below 25. Body mall index is calculated by dividing weight in kilograms by height in meters squared
Normal: 18.5 - 24.9
Overweight: 25 - 29.9
Obese: Above 30
This is of grave concern since the number of people who are overweight continues to rise.
