you can get small lumps (I did) in different areas which can be bad. Many doctors do not know about thee as there are a very rare type of secondary. But a scan wouldn't work as they are too small to show anyway. Needle check possible? But in the vst majprity of cases, I hasten to add, they ar just fine!! - I only gvie paranoid advice having had these myself on scalp as frst sign of retrun. Hope these are OK for you!
ps 95 % prognosis = come bavk anywhere AT ALL in the body
