Tobacco is the cause of 90 percent of lung cancers, and smoking increases the risk of more than a dozen other cancers, including cancers of the mouth, larynx (voice box), pharynx (upper throat), nose and sinuses, esophagus (food pipe), liver, pancreas, stomach, kidney, bladder, cervix and bowel, as well as one type of ovarian cancer and some types of leukemia. There is also some evidence that smoking could increase the risk of breast cancer. After quitting, you can expect these amazing changes:
- 20 minutes after quitting: Your blood pressure and pulse return to normal.
- 8 hours later: Nicotine, carbon monoxide, and oxygen levels in your blood begin to return to normal.
Smokers smoke because they want to. They have their reasons. Non-smokers don’t get it, unless they used to be smokers. But that’s okay; we’re all different. One thing is for certain though, smokers don’t light up hoping to get lung cancer. Crazy, right? We've all felt invincible at one time or another, especially when we're young. Cancer happens to other people, not us. So what if you smoke? Cancer doesn’t run in your family?
