Top best answers to the question «Why cancer is caused by tobacco»
- Poisons in tobacco smoke can damage or change a cell’s DNA. DNA is the cell’s “instruction manual” that controls a cell’s normal growth and function. When DNA is damaged, a cell can begin growing out of control and create a cancer tumor. Doctors have known for years that smoking causes most lung cancers.
