What? Smoking causes boob cancer?

No Scientific proof ever!!!

A true story, I know a lady. She's been single most of all her life (don't know whether or not she dated at her young age, but as far back as I remember, she's never been with a man or should I say, a smoking man).

A recent year, she was diagnosed with a breast cancer.

Well how do they explain the cause of her cancer? Smoking? What a joke!!!.
