9/24/2017Hi Lilly. I'm still pondering about previous post. I had a DMX with bilateral breast reconstruction with silicone implants. In one of the breasts there is an intracapsular implant rupture and a cyst close to scar but not in scar (in external upper pole quadrant) All this has been seen with an ultrasound. I'm still pondering how reliable is the ultrasound to indentity cyst vs cancer. 1) Is it possible that lump to be cancer isntead of a cyst? Is it reliable just to look at the borders of the lump with an ultrasound to identify them and discard cancer? I'm having a MRI (without contrast) to check implant rupture before proceeding to surgery replacement(about 6-8 months later I'll have surgery due to a waiting list) but MRI is not for checking the cyst. 2) I'm sorry to bother you again but I cannot stop thinking that they might have missed a cancer recurrence? Obviously a biopsy is not possible with implant in (risk of rupture/extracapsular)I hate worrying all the time. Thanks.

9/24/2017make sure the radiologist is a breast imaging radiologist. that said,

1. possible but doubtful. cysts contain fluid; solid masses do not. usually the US can show the margins/borders well. ask the radiologist how clearly they can be visualized. smart to get ruptured implant out. MRI will clearly show rupture and will be helpful in showing borders of cyst too. try not to fret.
