Although the use of injected liquid silicone for breast augmentation h
as all but ceased since its widespread use in the 1960s, patients with
injected silicone are still seen with a multitude of symptoms. Silico
ne mastitis is a well-documented phenomenon; however, there has been a
paucity of information regarding cancer detection in this group of pa
tients. We report 2 patients who presented with chronic mastitis but o
n further workup were found to have breast cancer. In bath patients, e
arly cancer detection was adversely affected by the presence of free l
iquid silicone. In view of this and other similar case reports, we adv
ise that simple mastectomy be recommended to those patients with breas
ts inspissated with liquid silicone who not only have suspicious masse
s but present with recurrent mastitis or a family history of breast ca
ncer.
