Hello, I'm a subject matter expert with a background in medical genetics. Let's delve into the question of whether hemangiomas are genetic.

Hemangiomas are benign tumors composed of blood vessels. They are relatively common, particularly in infants, and can occur anywhere on the body. The development of hemangiomas is complex and not fully understood, but it is believed to involve a combination of genetic and environmental factors.

While there is evidence to suggest that some types of hemangiomas may have a genetic component, it is not straightforward.
Familial cases have been reported, indicating that there could be a hereditary pattern in some families. However, these cases are rare, and the majority of hemangiomas occur sporadically with no clear genetic link.

Additionally, certain syndromic conditions, such as Sturge-Weber syndrome and Klippel-Trenaunay syndrome, are associated with an increased risk of developing hemangiomas, suggesting a genetic link in these specific instances.

In summary, while there is some indication that genetics may play a role in the development of hemangiomas, particularly in certain syndromes or familial cases, the majority of hemangiomas are not clearly linked to genetics. More research is needed to fully understand the genetic basis of these tumors.
