Q

When should mammo’s begin?

A

every 2 years from age 50-74

Every 2 years beginning at age 40 if increased risk factors – 10 years prior to the age the 1’st degree relative was diagnosed.

  • Clinical breast exam every 3 years in women age 20-39 years then annually after age 40
  • Breast self-exam monthly beginning at age 20 – immediately after menstruation on days 5-7 of the menstrual cycle

Q

Tx of breast cancer

A
  • Segmental mastectomy (lumpectomy) followed by breast irradiation in all patients and adjunctive chemotherapy in women with positive nodes stage I and stage II with tumors less than 4 cm in diameter
  • Anti-estrogen Tamoxifen is useful in tumors that are ER-positive – binds and blocks the estrogen receptor in the breast tissue
  • Aromatase inhibitors are useful in postmenopausal ER-positive patients with breast cancer – reduces the production of estrogen
  • Monoclonal AB treatment is useful in patients with HER2 positivity (Human Epidermal Growth Factor Receptor)
