Q
  1. What is the benefit of Modified Radical Mastectomy vs Breast Conserving surgery?
  2. What is a sentinel node biopsy?
A
  1. none, likelihood of cure is the same

2. removes lymph nodes that receive drainage from site of neoplasm; less invasive, fewer complications, more accurate

  4. Side effects (2)
  5. How long are they used?
A
  1. Anastrozole, Letrozole, Exemestane
