SMOKING: Cancer.
Your body is made up of cells that contain genetic material, or DNA, that acts as an “instruction manual” for cell growth and function. Every single puff of a cigarette causes damages to your DNA. When DNA is damaged, the “instruction manual” gets messed up, and the cell can begin growing out of control and create a cancer tumor. Your body tries to repair the damage that smoking does to your DNA, but over time, smoking can wear down this repair system and lead to cancer (like lung cancer). One-third of all cancer deaths are caused by tobacco.
QUITTING: Lower cancer risk.
Quitting smoking will prevent new DNA damage from happening and can even help repair the damage that has already been done. Quitting smoking immediately is the best way to lower your risk of getting cancer.
