Tutorial

 

Cancer is a disease caused by cells with genetic errors that divide without control. 

When the DNA in a cell becomes damaged it is called a Gene Mutation.

 

Gene Mutations (a change in a persons DNA sequence)  that cause cancer can either be inherited or caused by environmental factors.

 

Mutagens are environmental agents that damage DNA.

Smoking and X-ray exposure are causes of gene mutation.

 

Cells with damaged DNA have a higher likelihood of increasing a person's risk for developing cancer.
