It is possible for hemangioblastoma to be hereditary. Hemangioblastoma is a benign tumor, the probability of malignancy is very small, it may be congenital, or it may be caused by gene mutation. And there is a certain chance of heredity for this disease, but it does not mean that it is necessarily hereditary. If someone in the family has had hemangioblastoma, the incidence rate of their children and offspring may be higher than normal, so you can do regular body checkups to rule out the disease as soon as possible. If you are found to have hemangioblastoma, it is recommended to go to regular hospital for systematic treatment, such as surgical resection treatment, as soon as possible. If the disease is treated and controlled in time, the prognosis is generally good and the impact on the body is not great. However, the treatment does not mean that the disease can be cured once and for all, and it is necessary to go to the hospital for regular checkups and actively cooperate with the professional doctors to carry out the follow-up rehabilitation treatment.
