Hi,
Believe me, I am no expert. I never really asked, but I don't think that sonograms are as good at detecting cancers as mamograms. If they were, why wouldn't that be the screening tool of choice? They do show a better picture of the things that they see on mamograms. After doing some research myself, cancerous growths are characteristically irregularly shaped vs, the ones I have that are smooth and oval. They are easily seen on the sonogram along with cysts, which have a white outline, but are black inside. One of the fibroaednomas that the surgeon knew I had, and even I could feel for years, was not seen on the mamogram nor sonogram until this past time.
I think that she can feel irregularities before they show up on the mamogram. Especially since that is all that she does and she knows the texture feel of my breasts and also cancerous growths feel very different.
Do you get digital mamograms? They are supposed to be a little better. Also, the technician that did the sonogram said that MRIs are done routinely in Europe, but that insurance companies don't want to pay for them in the US.
Yours is probably nothing, but thinking about all of this is nerve racking.
