Q

Which of the following are breast cancer screening guidelines for women 30 years or older who are at an increased risk (at or above 20%) of developing breast cancer due to their family history?

21
Q

The following best describes the difference between a lumpectomy and a mastectomy:

  • A lumpectomy is a breast-conserving surgery where only the tumor and a small sample of the surrounding tissue are removed. In contrast, a mastectomy entails the surgical removal of the whole breast.
  • A lumpectomy is the removal of both breasts and surrounding tissue. A mastectomy is the removal of a lump in the breast.
  • A lumpectomy removes the entire breast. In contrast, a mastectomy removes only a portion of the breast.
A

A lumpectomy is a breast-conserving surgery where only the tumor and a small sample of the surrounding tissue are removed. In contrast, a mastectomy entails the surgical removal of the whole breast.

22
Q

  • Annual breast MRI screening is only offered to patients with a BRCA 1 or 2 gene mutation
  • General population breast screening includes annual mammogram and MRI beginning at the age of 40
  • Most breast cancers are detected at early stages (stage 1-2) due to the presence of a breast lump/mass found on self-breast or clinical breast exams
  • Patients at elevated risk (at or above 20%) of developing breast cancer may be eligible for annual breast MRI screening, in addition to mammography.
