This sure is a sneaky cancer! I also found what I thought was a lump, only to find out that the cancer was elsewhere in my breast and larger than I thought. I was fortunate in that I didn't have to wait for a mammogram, biopsy or diagnosis. I walked into the oncologists office blind. I knew nothing about the different types of cancer, how they are graded, what tests are done, and what test measured my possible outcome. I quickly learned! My suggestions on this journey are to rest when you need it, rely on others, eat well, and exercise when you can. I finished my last treatment 2 months ago and am bouncing back to my previous energy levels. Still nap occasionally though. Good luck and many prayers are going your way.
