Normally, hemangiomas < 1.5cm can be observed. Those larger than 5cm, or rapidly growing should have serial x-ray studies to monitor the progression.
If the hemangiomas spread or enlarge, you can consider surgery to remove them. There are also some non-surgical techniques embolization or radiotherapy that can be discussed if removal is considered.
I am not aware of an association with the lymph nodes. If they persist, you can consider a biopsy to ensure there is not a cancerous process going on.
Followup with your personal physician is essential.
