Is Breast Reduction Safe While Pregnant?

 Cancel the surgery and wait six months after you deliver.  It is unwise to operate unnecessarily in a pregnant woman.  Additionally, pregnancy changes the structure and composition of the breasts.  You really should wait.

It would be extraordinarily unwise to perform any elective surgery, especially breast surgery, while a woman is pregnant.
It would endanger the baby, and during the operation it would be difficult to estimate the type and amount of breast reduction to perform.
