I had pleomorphic lobular breast cancer, grade 2, stage 3A. Didn't qualify for oncotype testing because most of my cancer was noted in 6 lymph nodes. Started out with heavy duty chemotherapy which was very successful at killing cancer cells. Even noted by the pathologist after my surgery as an "excellent response."
IMO there's been so little research into this type of breast cancer that no one can be sure what treatments are most effective.
