Arm Intervention/treatment
Experimental: Breast Cancer
Breast cancer
Diagnostic Test: F-Var3 PET/CT
Participants will undergo up to 5 serial F-Var3 PET/CT scans within 25 minutes of the injection of 18F-Var3, 30, 60, 120 and 240 minutes after injection of the 18FVar3.

Other: Blood draw
Collection of blood for research tests before the injection, 30, 60, 120 and 240 min after the injection.

Primary Outcome Measures :
  1. Incidence of Treatment-Emergent Adverse Events as assessed by CTCAE v5.0 [ Time Frame: 30 days after completion of study treatment and assessments ]
    The safety of patients will be evaluated using Common Terminology Criteria for Adverse Events (CTCAE) v5.0. Grade 1 and grade 2 toxicities are considered safe.
