Q

What is the cause of fibroadenomas?

A

The cause of fibroadenomas is unknown, but they may be related to reproductive hormones

17
Q

Why is it theorised that fibroadenomas are related to reproductive hormones?

A
  • Because they occur more often during the reproductive years
  • Can become bigger during pregnancy or with the use of hormone therapy
  • They might shrink after menopause when hormone levels decrease
18
Q

Describe how a fibroadenoma feels?

A

It is a solid breast lump that is usually;

  • Round with distinct, smooth borders
  • Easily moved
  • Firm or rubbery
  • Painless
19
Q

Can a patient have more than one fibroadenoma?

A

Yes, they can have one or many fibroadenomas in one or both breasts

20
Q

What are fibroadenomas often termed?

A

‘Breast mice’

21
Q

Why are fibroadenomas often termed ‘breast mice’?

A

Due to their high mobility in the breast

22
Q

How can fibroadenomas be discovered if they are too small too feel?

A

Imaging tests

23
Q

How are fibroadenomas investigated?

A
  • Diagnostic mammography or breast ultrasound
  • Fine-needle aspiration
  • Core needle biopsy
24
Q

What might mammography show in fibroadenoma?

A

A breast mass with smooth, round edges, distinct from surrounding breast tissue

25
How are fibroadenomas managed?
In many cases, fibroadenomas require no treatment Some women choose surgical removal for their peace of mind
26
When may fibroadenomas not require surgery?
When you can be reasonably certain that the breast lump is a fibroadenoma based on the result of a clinical breast exam, imaging, and biopsy
27
Why may patients prefer conservative management over surgery in fibroadenoma?
* Surgery can distort the shape and texture of the breast * Fibroadenomas sometimes shrink or disappear on their own * The breast has multiple fibroadenomas that appear to be stable (no change in ultrasound compared to an earlier ultrasound)
28
What it is important to do if a patient chooses not to have surgery for fibroadenomas?
Monitor the fibroadenoma with follow-up visits to the doctor
29
What happens in follow up visits for fibroadenoma?
Breast ultrasounds to detect changes in the appearance or size of the lump
30
What are the surgical options for fibroadenoma?
* Lumpectomy * Excisional biopsy * Cryoablation
31
What happens in cryoablation?
A thin deviced called a cryoprobe is inserted through the skin to the fibroadenoma, and gas is used to freeze and destroy the tissue
