Clementine, I had both lobular and ductal cancer. My oncologist told me that the chance of recurrence was greatest in the first three years; after that and until 5 years there is a sharp drop off. He said that for my diagnosis, my chance of recurrence never drops to ...for the life of me, I can't remember! I'm pretty sure he didn't say 0, but maybe he did.
I believe these statistics were based on the size and type (grade, how aggressive) of tumors, and because the cancer had spread to more than two of my axillary lymph nodes.
A little bit different take on lobular cancer.
