Sporadic cancer 

The most common type and the one we usually talk about is sporadic cancer: 

  • It appears as individual cases, is unpredictable and, even when it affects more than one person in a family, is not hereditary. 

Environment + genetics 

Sporadic cancer tends to appear later in life, usually around the age of 60-70, and results from a buildup of mutations throughout the years. 

It is caused by exposure to environmental risk factors, but also by the person’s genetic blueprint, which can increase his/her vulnerability to the risk factors. 

An example of an environmental risk factor, in this case for lung cancer, is smoking.
