It will not come as a surprise to anyone reading this that smoking is bad for health – in big important ways and in some less life-threatening, but undesirable ways. As someone who has been diagnosed with breast cancer, I sincerely hope that if you are a nonsmoker your commitment to not smoke will be reinforced by what you read here and if you are a smoker that you will seize the opportunity to prevent adverse health effects by battling and beating cigarette addiction.
