Is it safe to have a breast augmentation after having my spleen removed?

As long as there are no ongoing medical issues and your blood counts are fine there should be no contraindication for breast augmentation after a splenectomy.  A competent plastic surgeon will go over this thoroughly during a preoperative consultation.

As long as you get a clean bill of health from your doctor then it shouldn't be a problem Schedule an appointment with a board certified plastic surgeon in your area (link below) to discuss your options. Best, Dr. Nazarian

Prior to having your breast augmentation surgery, I recommend that you have your blood counts checked and a thorough history and physical performed by your primary care doctor given that you have had your spleen removed.  If all is well, then yes it is safe to have a breast augmentation.  Good luck!
