on her breast is sounding like early thelarche rather than a <span style = 'background-color: #dae8f4'>lump</span>
, this sounds like breast tissue, bone on
one side is not unusual and the main goal is to
rule out early puberty, so a bone age is sometimes helpful but NOT in a 2 yo. At age 2 and younger it is best to
get a bone age of the knee rather than the wrist
which we get in children over 2, even that is hard to
interpret.So do not let the bone age alone make you panic.
