  • Age ≥45 years for all tumor types
  • All invasive subtypes or DCIS
  • Total tumor size (invasive and DCIS) ≤ 3 cm
  • T stage Tis, T1, T2 (≤ 3 cm) 
  • Margins; No tumor on ink for invasive tumors or tumors involved with DCIS;  ≥2 mm for DCIS 
  • Node negative 
  • Multifocal acceptable if total span of tumors is ≤3 cm
  • Estrogen receptor positive or negative
  • Focal lymphovascular invasion
  • No genetic mutations
