I went online to read about hilar lymph nodes after seeing my oncologist today. He mentioned the possibility of lung cancer or lymphoma. I brought up the possibility that the newly enlarged hilar lymph nodes and increase is lung nodes could be because a different hormone status from my breast cancer, he didn't say much. I have to wait about 3 weeks for a different type of lung biopsy from my first to check hormone status and to see if it's definitely breast cancer. My first lung biopsy they felt that it was lung cancer but could not be 100% sure. I was just wondering if there was anyone else who's had breast cancer metastasize to the hilar lymph nodes?
