2/2/2018Hi! I had a DMX, with shapped silicone implants under pectoral muscles due to a bilateral bc diagnosis at the same time about 4 years ago when I was 41. Stage 0 and Stage IIA. Both ER+ PR+, HErneu2 negative. I had chemo. No radiation. I found a nodule in the upper exterior pole close ot mastectomy scar now. Ultrasound indicates it's a cyst. Questions: 1) How can a cyst appear there, where there is almost nothing of breast tissue but just implants and muscles? 2) Is ultrasound a reliable test to determine a nodule is just a cyst? Any mistakes of diagnosis with this type of test? 3) Could it be cancer instead?

2/2/2018Because there is still a small amount of breast tissue left behind with a mastectomy (there has to be enough tissue to close the incision), there is always a slight risk of recurrence, so yes, a cyst could form there. Ultrasound is an excellent tool to visualize the mass. There is no way to know exactly what it is unless it is biopsied.
