Introduction
In general, neurofibromas are benign tumors that grow slowly and do not metastasize, posing relatively little harm to the body. However, in rare cases, they may show malignant tendencies and thus require regular monitoring. In daily life, if neurofibromas are detected, it is important to observe the tumor's size, consistency, and any accompanying symptoms, while avoiding repeated compression or irritation of the tumor site.
Generally, neurofibromas are benign tumors that grow slowly and do not metastasize, posing relatively minor threats to health. However, in rare cases, they may show malignant tendencies and thus require regular monitoring. Detailed analysis is as follows:
Most neurofibromas are benign. The tumor cells proliferate slowly and do not invade surrounding tissues or spread to other organs. They commonly manifest as soft, palpable masses on or under the skin; some may be accompanied by localized pigmentation. If these benign tumors do not affect bodily functions or cause discomfort, they can simply be monitored regularly. However, if tumor enlargement compresses nerves and causes pain or numbness, or if they affect appearance, surgical removal can be considered. The recurrence rate after surgery is low, and their impact on daily life is generally minimal.
A minority of neurofibromas may undergo malignant transformation—for example, if the tumor rapidly enlarges within a short period, becomes harder in consistency, or is accompanied by intensified pain or ulceration of the overlying skin—prompt medical evaluation is necessary in such cases.
In daily life, if neurofibromas are detected, it is important to monitor their size, texture, and any associated symptoms, while avoiding repeated pressure or irritation of the tumor site.
