I am really concerned that your baby is suffering from lipoma.
If the diagnosis is lipoma then you need not worry. It is a harmless lump and doctors may leave it without treating it. Surgery is needed if the lump increases in size or cosmetically looks bad. Lipomas
do occur in babies. We cannot prevent them from coming, but they are not a cause for concern.
Don't worry everything is going to be alright. Take care.
