Hello Ve4016!
 

Have you asked them for the BIRAD Score? Are you in England/Scotland?  I would be proactive and apply to your hospital to see the exact FULL copies of your radiology reports.  You can also request for a CD of your actual scans.  There are several different features that they look for on Mammograms and Ultrasounds to determine the likelihood of malignancy.  The fact that they didn't do a biopsy previously would suggest that the lump didn't meet any of the criteria normally fitting to malignancy.  There are other benign conditions that could possible cause the mass to grow.  My guess would be that they are just erring on the side of caution.  Although not unheard of, the likelihood of breast cancer at your age is statistically quite low (Although if you have the BRACA gene/family history, that may increase your risk).  I underwent treatment for breast cancer 4 years ago when I was 40, and leading up to my diagnosis I had shooting pains in my armpit (on my BC side).  I went for a  mammogram and ultrasound yesterday because my annual mammogram the week before showed a new shadow on my opposite breast.  I told the Dr about the shooting pains in my armpit of the opposite breast (& multiple spots where there is skin puckering) and told him how I experienced this prior to my first BC diagnosis.  He was very rude/blunt and said BC doesn't cause pain (that's a myth!) I can't see anything, your good to go.  My point is, you may have nothing to worry about but don't ever feel scared to push them for specific answers.  Access and read up on your full reports and if you still need clarification, make a list of all the questions, ask for the name/email of your consultants secretary and send them an email listing all the questions.  I hope that you manage to resolve things and get a clean bill of health.  Best wishes, Emma

Thank you! I'm not in the UK, I'm actually in the US, but I definitely will call and ask for a copy of my radiology reports and images. I can't stop freaking out. I've had shooting pains in my armpit since I was 17 too, but I always thought it might have had something to do with my tumors sitting on nerves or something. Gosh that's scary. What scares me the most is that they want to do a breast mri. I have dense breast tissue so I've never had a mammogram, so I thought maybe they want to do an mri because it might be more effective for my breasts? I'm not sure. It's just all so scary.
