Hi Nan-
I can't answer your question about the 2 being related. I have heard of women who have 2 lumps, one benign and 1 cancerous, both benign or both malignant. And even if both are malignant, they can be totally different cancers. The path report would give information related to that, based on cell type, etc.
Yes, often a radiologist can tell, but not always. In my case, the mammogram did not show my tumor, which was 2.5 cm (I was 30, and they often cannot read much in the mammo of a younger woman). I learned after the fact, that the u/s showed the tumor "was highly suggestive of malignancy". I think it depends on what they can see...in my case, they could see different densities throughout, rather than a homogenous and evenly distributed texture. Plus the borders were uneven and mis-shapen, another red flag.
I had the u/s and went to see the surgeon before the films were read officially by a radiologist. My surgeon had a radiologist in her office read it, to help her determine how to proceed surgically, and "he had some concerns about the borders." But they seemed interested in taking it out before they knew it was cancer, it is pretty common to take it out. And it is routine to biopsy anything that they remove, even if they know it looks benign. THey have to evaluate it on a cellular level.
When do you see the surgeon? Did he say which "signs" he was not comfortable with?
At any rate, hang in there....we're waiting with you!
