5
- Often multiple, usually bilateral masses
- Rapid fluctuation in size is common
- Painful and tender
- Pain occurs or increases during the premenstrual phase of the cycle
- Size increases during the premenstrual phase of the cycle.
Specific diagnostics and treatments: Fibrocystic changes?
8
- Reexamine patient at intervals
(Negative cyst that does not resolve over several months may need to be excised.) - Reassure patient that discomfort is not a sign of cancer
- Symptoms usually improve with the cyclical decrease in hormonal stimulation
- Use support bra
- Vitamin E supplements
- Avoid chocolate, alcohol, and caffeinated beverages.
- Teach and encourage monthly BSE.
- May need to be biopsied.
Fibroadenoma:
- What is it?
- Can occur in what pattern and which is indicitive of cancer?
- Occurs most frequently in who?
- Tends to occur early in what population?
- Women over ____, need to distinguish from fibrocystic change or cancer.
- Benign neoplasm made from an overgrowth of glandular and fibrous breast tissue.
- Can occur alone, in groups or as complex. Complex fibroadenomas can raise risk of breast cancer slightly
- Occurs most frequently in young women, usually within 20 years after puberty. Clinical diagnosis is not difficult.
- Tends to occur at an earlier age in black women.
- 30
Physical presentation
Fibroadenoma?
7
Fibroadenoma
- Round or ovoid
- Non tender
- Smooth margins
- Rubbery
- Discrete
- Relatively movable
- 1-5cm in diameter
Fibroadenomas: Specific diagnostics 3
Rx?
4
Fibroadenomas
- Ultrasound can distinguish cystic. Fibroadenomas show up well on ultrasound.
- FNB can confirm cytology.
- Teach and encourage BSE.
- Since fibroadenomas are benign, treatment will vary depending on the diagnosis.
- If it is small, painless, remains the same size, and a biopsy shows no problems, further treatment not needed but likely follow-up ultrasounds.
- If it is large (more than 3cm), painful, growing, or a biopsy results in atypical cells, the tumor can be removed.
- It is recommended that fibroadenomas be removed in women over age 40.
If rapidly growing need to rule out what?
phyllodes
Two key differences between fibroadenomas and phyllodes tumors are?
- phyllodes tumors tend to grow more quickly and
- develop about 10 years later in life — in the 40s as opposed to the 30s. These differences can help doctors distinguish phyllodes tumors from fibroadenomas.

Who is US imaging the preferred examination for? 3
Ultrasonography is preferred if a 1. palpable mass is found, 2. if a patient is younger than 30 years, or 3. if the patient is pregnant.
- US can differentiate between what types of masses?
- Why is this important?
- US is also used for what?
- Can differentiate a cystic from a solid palpable mass.
- 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.
- US is also used for guidance for needle localization if mass is not palpable, but found on mammogram.
- Who is mammography the preferred method of imaging for? 3
- Sensitivity is much reduced in who?
- Usually follow-up with ___ if determination between cystic and solid mass is needed.
- Mammography -
- if the patient has a palpable mass, is
- older than 30-35 years, and is
- not pregnant. - Sensitivity is much reduced in
- younger or denser breasts; therefore, mammography is considered inappropriate in patients younger than 35 years. - US

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