welcome to health care magic
Regarding your query fibroadenosis
is a benign breast condition also known as fibrocystic disease
It is seen in mostly young age women,producing tendrness ,pain,small lump..
It does not evolve in to cancer...your fnac report also says it is fibroadenosis..so need to worry much about this..
take evening primrose oil,evoin tab.
Forget about the presence of small lump and enjoy the married life..
if the size is increasing then consult general surgeon
for further suggestion ..
hope you understand my suggestion
