Sorry to hear you have this anxiety after all you’ve been through.
Hopefully all’s well & they just need to double check something. I don’t know where the thread is, but another lady here recently was recalled after annual mammo & all turned out to be well, it was scar tissue, if I remember rightly.
Wishing you the best & do come back if you need to.
Ring the nurses on this site or Macmillan if you don't feel able to contact your hospital or GP, don't panic alone. Good luck
