14 yo daughter with fibroadenoma

Did they biopsy it??

I have absolutely no expertise in this, but I did find this one case report in Pubmed from 1989.  I know far less about bone tumors than breast tumors, so I have no idea if this case report is even relevant to your daughter's situation.  In this case report, if I'm reading it right, they are speculating the breast tumor may have bone origins.

This is just one case study.  I don't understand lots of the Pubmed references, but I don't see other clinical studies in Pubmed looking at the association between the two conditions, so I'm guessing there is no huge association between the two conditions.  Obviously I'm no expert.  Glad you're getting this checked out.

Best wishes!

In teenagers who present with a fibroadenoma, often a biopsy is not done and is not considered necessary.  In many cases, monitoring is often the preferred option. 

From the NIH: Fibroadenoma - breast

Women
in their teens or early 20s may not need a biopsy if the lump goes away
on its own or if the lump does not change over a long period.

From UCLA: Benign Breast Problems

The first step for any woman who has found a breast lump is to have a
breast examination by a doctor. The lump for a fibroadenoma is usually
firm, well defined on palpation. In young women, ultrasound evaluation
may be the only necessary study beyond doctor's examination.

From Radiopaedia.org:  Fibroadenoma of the breast

When a lesion has the typical features of a fibroadenoma on ultrasound
and there are no clinical red flags they can be safely followed
clinically.

The normal approach to diagnosing and treating a fibroadenoma in a
teenager or woman in her early 20s, assuming that the ultrasound imaging
clearly indicates that the mass is a fibroadenoma, is not the same as
the diagnostic process and treatment recommendations for someone who is in her 30s or older, who presents with what may be a fibroadenoma.

I had my first fibroadenoma at 16 and then
another at 20. The first was surgically removed because it was so large - and back
when I was 16, they didn't even have ultrasounds. My second was left
in place for years with no imaging done and no biopsy.  It was large too, and because it didn't shrink, eventually I
decided to have it removed.

alemankc, fibroadenomas are not particularly unusual in teenage girls.  My guess is that this is not related to your daughter's other benign tumor, but it will be interestingto hear the surgeon's perspective on that. It will also be interesting to see if the surgeon recommends a needle biopsy or whether he feels that the imaging is clear enough that monitoring is sufficient.

I had a 5cm lump when I was 17.  My doctor tried to aspirate it but it was solid so I was sent for a mammogram. I don't remember a needle biopsy or ultrasound (it was the late 80's). I consulted a breast surgeon who wanted it out because he felt it was large enough that it could obscure imaging in the future.  I had two more fibroadenomas removed from the same breast when I was 29. I had cancer in the other breast at 42 and pathology from my BMX showed only "fibrocystic change" (benign) in the lumpy breast.  

I don't know about the correlation between bone/breast masses, however, I was ~14 when I noticed my first mass and 16 when I was first diagnosed with fibroadenomas. In my experience, they were the most painful when I was younger. I was happy to have the most troublesome ones removed, but now that I'm 26 I'm still dealing with getting new ones and monitoring the older ones.

I did have some uterine fibroids and ovarian cysts. So, I guess I'm just bumpy too haha. No bone bumps that I know of, and I've never heard of a connection between any of these things.
