i don't know what your particular chances are since i do not have enough information about you or your mother's case but needless to say you may have a higher risk so a proper biopsy of that enlarged lymph node and careful examination some diagnostic tests and perhaps an early mammogram would be prudent in your case.
the chances of cancer. i am a 33 yr old woman. the dr is sending for biopsy for enlarge lymph node in armpit. my mother had breast cancer that was removed and came back with lymphoma and passed away 2003. what are my chances of this being the same as her.
