How does something like alcohol or tobacco cause cancer?
In: Biology
DNA duplicates duplicates duplicates. To make every cell in our body. We often get errors in our DNA but our body can quickly fix it. When we get errors that are in our DNA that our body doesn’t fix and then it replicates the errors this is called cancer. Being exposed to carcinogens is one way our body makes those DNA errors (mutations). The more errors the less likely it will be caught and MULTIPLY (=cancer).
