Please help: I had a FNA biopsy with no results

Migz - where are you located? If the biopsy is "negative", there's no diagnosis. What kind of doc is this? Since the doc is concerned and you're not sure, I'd make an appointment for a second opinion with a breast specialist.

I agree that FNA is not a great dx tool. I also agree that, like most in your situation, the unanswered questions are anxiety provoking.

The words surgery and operation can be scary. You may simply need a biopsy of the area in question. When you see the surgeon, breast specialist or whoever is part of your next step, ask about what they are recommending and why. I had a stereotactic and ultrasound guided biopsies on the same day. I wouldn’t really consider them operations/surgeries at all. There is such a thing as a surgical biopsy, essentially a lumpectomy, but since you don’t yet know what is being proposed try not to get ahead of yourself. Regardless, breast cancer is generally not considered an emergency. I know you want answers quickly but be prepared to do a bit of waiting, especially with Covid19, and rest assured that this is unlikely to effect your situation even if it turns out to be cancer.
i wish you all the best

"And now they want to send me straight to a surgeon" That doesn't necessarily mean that surgery is required. It just means that the results weren't clear so it's suggested that you see an expert. A breast surgeon is the expert on what to do when something abnormal shows up in the breast. The surgeon might suggest watching, he might suggest additional imaging, he might suggest a core needle biopsy - I expect that an excisional biopsy (a surgical biopsy) would be the last option he would consider. Usually other diagnostic options are used first before any suggestion of surgery.

"I always assumed a FNA could actually give us a diagnosis.". No, as the others have side, a FNA is not good for biopsies. A FNA is usually used for cyst aspirations. But if the needle goes in and it hits something that clearly isn't a cyst (cysts are fluid-filled), then usually you have to move to plan B because the FNA won't be much good. So there's nothing much unusual about your situation in this regard.

Right now you are jumping to a lot of conclusions just based on the fact that it's been suggested that you see a surgeon. Think of it instead as seeing a breast specialist (who happens to be a surgeon). Talk to the breast specialist and see what the recommendation is before you assume what will happen next. Unfortunately none of us can tell you what the breast surgeon will suggest because every situation is different.
