Do breast surgery or reduction kill ?

Very very low odds: It's possible to have a rare complication - like a major anesthesia mishap, a drug reaction, a pulmonary embolism that could be lethal after any kind of surgery. But in well-trained hands, in an accredited facility, the odds of death from a breast reduction would be very small indeed.

Very Rare: The risk of death associated with elective breast surgery, assuming good patient health and careful selection of plastic surgeon, anesthesiologist, and surgery facility, is extremely low. Your plastic surgeon will be able to address your concerns more specifically. Best wishes.

Breast surgery: Not sure if you are asking about general pain or fatalities. Pain is usually well tolerated. There is always risk of surgery. The main risks are bleeding, infection and anesthesia complication. All are rare. Best to see your board certified plastic surgeon and see if you are a candidate..
