Hi there...........I am going through pretty much the exact same thing!!!!!! My lump is not palpable as it is 6mm. I went for an ultrasound last week, and guess what???? The radiologist couldn't find it. What they should have told you is that not all tests show all lumps/masses etc. Just because you can feel it/can't feel it doesn't mean every test will pick it up. So so so frustrating!!! Did you get the results of the diagnostic mammo?? Did it show up on that?? I would definitely ask for further testing, such as a breast MRI, especially since you can feel it and had some discharge!!!!!! It doesn't mean the mass isn't there because u/s didn't pick it up. Mine didn't, but found a tinier lump, that they then "lost". Again, ask for further testing. Oh, I just re-read your post, the tech did see the mass on the diagnostic, correct?? Then, yes, you should have more tests done! You can hang on to your films in case you need to show another dr, etc. If you look at other posts, message boards, etc, you will see our situation is not uncommon. Please keep us updated!!! Take care, hope this helped a bit,
Sue, glad I could help. Let us know how evertything goes tomorrow. Also, I see you're hypothyroid. I am as well, I had 1/2 my thyroid removed last year. I had a big 4cm tumor, along w/ Hashimotos. I was hypo before all that....still think I could use more meds, but my endo didn't want to increase. Thinkin' about switching docs, but that's a different story!! Good luck tomorrow!!
