Thank you for the information. Is it the hospital that keeps the slides? This test has never been mentioned to me. I will ask my oncologist about it the next time I see him. I think it is a moot point for me as I am getting the bilateral mastectomy with reconstruction next month and I have the CHEK2 mutation, but knowledge is a good thing. I have never come across a mention of the test with all the reading I have done on BC and related topics.
