Jan 15 for me too...and I have to tell them my aunt just had a mastectomy including lymph nodes and now faces chemo, first in our family. Hopefully it will be no big deal. If we ever have girls, it will suck for them though--now we have it on both sides--DH's mom is stage 4 and now this .
Depending on the Dr., they might not even care. My wife has had three grandparents die from breast cancer (yes, one was male), as well as several aunts and cousins. But because none of them are a first-degree relation (parent, child, or sibling), according to her doc, it does not matter.
