1/31/2018Just a follow up since I don't think my last question was clear??
I have Invasive Lobular Carcinoma which is usually often found in both breasts. My complex cyst has a mass which requires biopsy. So in this instance is it possible , with microcalcificatins already present, that it is possibly early cancerous? There is a slim chance complex cysts are malignant? Thanks again

1/31/2018Yes, ILC can be found in both breasts, however, it does not "travel" from one breast tumor to form another tumor in the other breast, meaning it would be a second cancer if found in the other breast. Microcalcifications are usually benign, but require following in case they change. A "complex" cyst refers to cysts that contain something besides clear fluid. This is usually something harmless like an old blood clot or debris. There is a very small chance that a complex breast cyst could be associated with malignant breast cancer.
