Worried, but trying to take it moment by moment

Long time lurker to this forum. Long story short, I was diagnosed at 25 ( left side lumpectomy, radiation and tamoxifen for five years) and then 2 years ago at the age of 34 ( left side again, chemo, node surgery, radiation, arimidex and monthly lupron shots) I have mammograms and MRIs every six months, and about to get them done on Wednesday. I feel something on my right side, under my armpit...and I'm dreading having to tell my dr about it. I know we'll have to check it out and most likely have to get a biopsy (makes sense!) Trying to stay in the present, but the area feels very much like it did two years ago.

Both times I have found the lump myself. Just making sure my insurance is in order and my HSA is funded correctly.
