Is hemangioma considered a major illness?
In general, hemangiomas are not considered major diseases. The specific analysis is as follows:

Hemangiomas are benign tumors that usually grow slowly and have well-defined borders. They do not invade surrounding tissues or metastasize to distant sites, and the prognosis is generally favorable. Most patients experience no obvious symptoms; only a minority may develop local compression or bleeding due to the lesion's special location or large size. With proper treatment, most cases can be cured, posing minimal threat to life and health. Therefore, hemangiomas are not classified as major diseases.
Regular monitoring of the size and morphological changes of hemangiomas is recommended, along with avoiding repeated friction or irritation to the affected area. If abnormalities such as pain, bleeding, or rapid growth occur, prompt medical evaluation is necessary. Seek care at a reputable medical facility and follow an individualized management plan based on the lesion’s location, size, and other factors. While excessive anxiety is unnecessary, risks should not be ignored—appropriate, science-based interventions are sufficient to ensure health.
