Glad to hear it on the insurance. I still can’t find anything that links “strawberry” hemangiomas to increased cancer risk, even from sunlight. I suppose that, since they are a form of tumor (although benign), being susceptible to them might also leave one more susceptible to other forms of tumors, but I can’t find anything that shows that strawberry birthmarks are directly more vulnerable to becoming cancerous or that resolved hemangioma sites are more vulnerable.
Of course, your child had them all over, which is unusual. IANAD, but to me that would signify some underlying issue that would increase the cancer risk, not the actual hemangiomas (which everything I can find say are harmless). My daughter only has one, and it’s (luckily) not on her face.
My sister didn't find information right away either. The docs kept telling not to worry but the birth marks were painful to her daughter, even to the slightest touch, so she didn't give up until she found a dermatologist specialist that had actually studied strawberry birth marks and knew the harm they could cause if left untreated. Now, mind you, most strawberry marks do take care of themselves as the child ages. We have a step grandchild born with a prominent one on her face and the maternal grandmother kept harping at the daughter "why don't you get that removed"...starting when the child wasn't even a month old! I nearly came unglued at the baptism over it, but held my tongue and put her in her place diplomatically. The daughter refused to cowtow to her mother and today the child is 2 and there is no sign of the strawberry mark. God indeed took care of it. But for persistent strawberry birth marks, you need to find a specialist who knows what they are doing and unfortunately, it is probably not going to be on the internet.
