While the treatment is generally very effective, it is important to note that electrodesiccation does not always result in complete eradication of neurofibromas.  Neurofibromatosis is more like a network of tumors of all sizes that are interconnected. They more often resemble “roots of a tree” than a single tumor. This is an important distinction because electrodesiccation will only treat the superficial portions creating the bump and not the deeper tumors. Therefore, to some degree, the neurofibromas will persist beneath the level of the skin.  Although treated areas do not typically develop tumors again, there is a chance of new tumors growing immediately adjacent to these areas as a result of the progression of the disease. However, the overall improvement of skin contour can improve aesthetics and restore confidence dramatically.
