Environment and cancer

What is environment?

For most people the environment is synonymous with nature: forests, oceans, mountains, flowers, etc.

For researchers, the environment is everything that is outside the body and which comes in contact or interact with it.  These interactions are called exposures.

Therefore, environmental exposure may include factors such as the sun, radiation, viruses, bacteria and all the chemicals that can be found in air, water and soil of our workplaces and of life as well as our choice of lifestyles such as smoking, excessive alcohol consumption, unhealthy diet, the lack of exercises or sexual habits that increase our exposure to risk factors.

Important Fact

The environment is a factor in more than 90% of cancer cases.
Only 5 to 10% of cancer cases are due uniquely to genetic factors.
