With the average 36C breast weighing between 200 grams (8oz) and 300 grams (12oz), this uncontrolled movement puts great strain on the breast's fragile support structure, which comprises only the outer skin and a connective tissue known as the Cooper's ligaments
Dr Andrew Hopwood of Queen's Medical Centre, Nottingham, says: "The breast is supported by a gristle-like structure called the Cooper's ligament
, which connects the skin to the deeper tissues near the pectoral muscles.
The sutures were then passed up through Cooper's ligament
and tied extracorporeally using laparoscopic needle holders and placed using knot pushers while the bladder neck was elevated intravaginally to the correct position.
While aging, gravity, heredity, pregnancy, and weight loss all contribute to a loss of breast shape, the stretching of the Cooper's ligaments
is the main reason that breasts droop.
In turn, this causes the breasts' main support system, the Cooper's ligaments
, to be put under stress leading to over-stretching.
