There are multiple options available for reconstruction of the breast following breast cancer surgery (oncoplastic breast surgery). In the setting of augmentation required for symmetry of the breast, flaps of tissue from the patient’s own body (such as the abdomen) or synthetic implants can be used. Synthetic implants commercially available include saline, silicone/gel and combination products.
From an aesthetic perspective, the choice is best made in consultation with your plastic/breast surgeon. From the viewpoint of a breast imager (radiologist) in terms of future breast cancer screening, there are pros and cons to each of the options, but none overwhelmingly outweigh any other. Officially, there is no recommendation.
