Phyllodes tumor, not benign, not malignant, but in between?

Hello, yesterday I called the surgeon about exercise restrictions after my lumpectomy. "Don't lift anything heavier than ten pounds?" They cut into a blob of fat! Fat doesn't need to recover! So although we thought I had a fiberadenoma, learned I have a phyllodes, borderline (benign, borderline, malignant). Wonderful. Just what I wanted to learn right before Christmas, I will return to meet with the surgeon to discuss the plan. To complicate matters, on January 19, 2016, I had open heart surgery to repair an aortic aneurysm so I take blood thinners. Joy to the world.

I knew about my aneurysm for four years before it was repaired. On my other disease forum (how many disease forums must I join? Someday I will probably join a disease forum for people who go on disability because they don't have time to work and keep up on all their disease forums) we called this "the waiting room." Have diagnosis, now wait. At this point, I am inclined to have a mastectomy. I am getting tired of surgery & if I could just get it done, I would. And if I can get reconstruction with a tummy tuck, all the better. Lift and tuck. Are there any members who had this borderline phyllodes; if so, I would love to hear from you. I know this condition is rare, but a few questions I have are:

Does it occur in both breasts, or just one?

Best places for treatment?

Anyone get reconstruction?

I know I sound sarcastic but I am actually a nice person. Don't mean any offense or harm.

Sincerely, Amy
