Concern?

[mmerritt100]

I had my very first mammogram and then a call back that required another mammogram and ultrasound. The mammogram showed a 7mm focal asymmetry in the area near my underarm. It had a rounded appearance with partially obscured margins and no definite fatty cleft. I received a Bi-Rad 3. It was recommended that I come back in 3 months for a follow up. The radiologist thinks it is a lymp node, I can not feel anything nor could my doctor. My doctor recommended me to get a second opinion this Friday with a surgeon.
My question is why did this spot not show up on the ultrasound? The tech and radiologist spent almost forty five minutes looking for it.

These two tests are very often used together because each can "see" different things as well as "seeing" things differently. I hope that makes sense to you even though it sounds rather odd :)  I would think the recommended 3 month follow-up would be the norm in this case but if you or your Dr are not comfortable with that wait then by all means get a second opinion. Be sure that the films are available for the Surgeon to review at your appointment. At 7mm in size I'm not surprised that this couldn't be felt by anyone. Lymph nodes are bean sized as a rule and may well be not that close to the skin surface. Hopefully you will get more detailed information when you see the Surgeon on Friday. Kindest regards ....
