Fibroadenoma birads three.. Could t really be cancer

Fibroadenomas are the most common lump in young women. They are harmless. I had two, one in my teens and one in my early 20s. In younger women, who are highly unlikely to develop breast cancer, if the imaging is very clear that the lump has the appearance of a fibroadenoma, a biopsy is often not required.

Fibroadenomas are less common in women over 35. And once you hit this age, the risk of developing breast cancer starts to increase. Therefore even if the imaging clearly indicates a fibroadenoma, usually an ultrasound-guided core needle biopsy is recommended just to confirm that the lump is in fact a fibroadenoma. If it is, then nothing more needs to be done.

A "Birads 3" is given for any mass that has a <2% risk of being cancer. A 6 month follow-up is the normal next step. A "Birads 4" is given for any mass that has a 2% or greater risk of being cancer, and the normal next step for a Birads 4 is a biopsy. So it's a fine line between a Birads 3 and a Birads 4. From what I've seen on this board, usually when a fibroadenoma presents in women over age 35, the Radiologist gives the imaging a Birads 4 so that a biopsy can be done to provide confirmation.

As an FYI, 'scattered fibroglandular density' is the second lowest category of breast density, so it's means that your breasts are actually less dense than average. This is good for imaging.

I had my fibroadenoma biopsied when I was 25 or so as mine grew from the original size then after that I was doing ultrasounds every 6 months for two year and then yearly. fibroadenoma looks different than cancer on the ultrasound. my technician and radiologist were available to notice the lump I had (far from the fibroadenoma) was cancerous on the ultrasound as the examination was being performed and I have dense breasts.
