Hi,
There really is no one best type of breast reconstruction - the approach needs to be individualized to the patient. A DIEP (Deep Inferior Epigastric Perforator) flap can be an elegant option to reconstruction with minimal morbidity to the abdominal wall and a very natural looking result. If you do not have any fat on your abdominal wall, however, the size of the reconstructed breast may be limited. A one-stage latissimus with implants will allow for a larger reconstructed breast.
Given that you have had radiation therapy, both surgeons are correct in wanting to use some kind of flap in your reconstruction; implants by themselves would not have nearly as good a result.
Ultimately, your choice of operation will depend on your choice of surgeon. If you cannot make up your mind, a third opinion from someone who has the opportunity to talk with you and examine you may be useful.
Best of luck. Hope this helps.
