Maybe lobular breast cancer is categorized differently but a 2.8 cm for invasive ductile cancer would be a higher stage than 1A. (The tumor removed from my breast was 5mm, 7mm including clear margins. And the stage was 1A.) I mention it in case it was a mistype.

I know these treatment decisions take a lot of thought and trying to balance everything. Second opinions, especially with a doctor who carefully listens before carefully explaining options, cam make a huge difference in one's confidence in choosing what to do next.
