What people usually ask about this location.
There are no fixed days per location. We give you the nearest date at Siglo 21; if you need an early appointment, Santiago usually has availability sooner.
It depends on the case; it is arranged when you book. Ablation is performed in Santiago.
When something is found in the thyroid, the endocrinologist manages the hormonal side and the surgeon decides what to do with the nodule. Dr. Jacobo is a surgical oncologist focused on thyroid interventions, and works alongside your endocrinologist, who remains in charge of the hormonal side.
If another location suits you better.
It would be a pleasure to review your case with you.
In person in Santiago, Santo Domingo or San Francisco de Macorís, or virtual from wherever you are.
