[|Human|] hi, i have a son that is a year and 3 months old and he has all these bumps on his belly they are getting worse and they now have blood in them and he has been to the doctor and they say its CM not to sure on the actually word but it seems to be getting alot worse what do i do?
[|AI|]  Thank you for the question. This word CM is not a widely used abbreviation to my knowledge. Maybe he meant Congenital Malformation like Hematoma which is a group of small blood vessels clumped together as a birthmark. It could sometimes enlarge and definitely have blood in the blood vessels as you say. If injured it could bleed profusely. Other bumps that can occur are congenital neurofibromas which will be soft somewhat solid or rubbery in feel. I suggest you to discuss with your doctor. If anyone comes to me, I would explain the nature of his condition. Regards.
