Who is US imaging the preferred examination for? 3
is preferred if a

2. if a patient is younger than 30 years, or
3. if the patient is pregnant.
1. US can differentiate between what types of masses?
2. Why is this important?
3. US is also used for what?
1. Can differentiate a cystic from a solid palpable mass.
2. This distinction is important because cysts are usually not treated, but a solid lump must be biopsied to rule out cancer. In a breast biopsy, a piece of the lump is taken out and tested for cancer.
3. US is also used for guidance for needle localization if mass is not palpable, but found on mammogram.
1. Who is mammography the preferred method of imaging for? 3
2. Sensitivity is much reduced in who?
3. Usually follow-up with ___ if determination between cystic and solid mass is needed.
1. Mammography -
-if the patient has a palpable mass, is
-older than 30-35 years, and is
2. Sensitivity is much reduced in
-younger or denser breasts; therefore, mammography is considered inappropriate in patients younger than 35 years.

2. Uses large gauge needle (14-18) to obtain tissue
3. Excisional Bx
-Only definitive diagnosis of breast cancer
-Often therapeutic without additional surgery.
