I’ve had my silicone breast implants for 24 years now. When I go in for my yearly mammograms the techs always tell me that they can’t tell they are there until feeling for them. ( They are behind the breast bone.) Anyway my question is ,is 24 years too long ? Are they ok? All the breast pictures indicate they are still in tack. I went from a small “A” to a “B+” more or less,with age, weight and time they are now”C’s” Too long, or all is well? P.S. I’m in CA. So the state is obtuse.
