Hi @ddon - lobular Cancer can be very different to ductal yet most oncologists don’t treat it differently. This is part of the problem. The research that has been done so far, supports that most (not all) lobular cancers have very specific characteristics in terms of being hormone responsive, responding to chemotherapy etc. The other thing about lobular is that it is recognized to metastasize in a different way. I recommend that you look at the information on this website - there’s a lot of excellent information.
