I'm going to be 77 years old. Is it too late for a breast lift?

No, age is not a limiting factor for breast lifting surgery, but good health is. I would ask that you be evaluated by your primary care doctor prior to surgery (medical clearance for elective surgery)  and select your plastic surgeon carefully.  Make sure that he/she is a well experienced board-certified plastic surgeon who can demonstrate lots of examples achieving the types of outcomes you will be pleased with. Safe anesthesia and surgery facility are also key. Best wishes; hopefully, your only regret will be not having had the procedure performed earlier.

Thanks for your question. 77 could be a fine age for a breast lift. I performed a lift several months ago on a 73 year old and she did quite well and was very happy. She now plans on having a facelift. Patients of any age are routinely screened for health issues; if they are medically stable for surgery it's a go. Surgery is not for everyone but for those who chose to enhance their appearance, it can make a significant difference. For more information on this and similar topics, I recommend a plastic surgery book like "The Scoop On Breasts: A Plastic Surgeon Busts the Myths." Best of luck to you.
