Will having fibrocystic breasts affect my ability for a breast fat transfer?

In and of itself, fibrocystic breasts should not impact breast augmentation or the outcome of the surgery.  You should continue with annual mammograms for early detection of any breast lumps.

Even though you have fibrocystic breasts, you can still have fat grafting. I would suggest getting a recent mammagram before the grafting.

Having fibrocystic breasts should not be a problem with fat transfer. Assuming that you have been carefully evaluated by your doctor (preferably with a mammogram), your condition can be problematic but not dangerous. Fat is placed in various levels into the breast during a transfer. When placed smoothly, the contour of your beast should remain natural. If your condition is more severe with bulges that can easily be felt or seen, it might make fat transfer more difficult. Since your condition is worse before your period, I would advise you to schedule your surgery after the swelling has resolved. That way, the transient swelling of your breasts can interfere less with the planning of your surgery. Your breasts can still be swollen periodically, but they should have a better shape and volume.
