what causes hard lump in fibroglandular breast tissue,in just 1 breast??

[twiglett]

Im 28 yrs old,no family history of breats cancer,as far as i know.
i recently had a miscarriage,i was only 6 wks pregnant(so very early stage)
I found a hard lump in lower left breats,went to GP who sent me for ultrasound, the ultra sound showed fibroglandular breats tissue,thats what they told me.
I have asked for a biopsy,even though the consultant said to wait 3 months,and he said it might be gone by then...
I did have a similar lump in same place about 13 mths ag,that went on its own,GP told me it was just normal breats tissue,i didnt have any scans for that 1.
I have no discharge,but sometimes slight pain(more of a tinglling really.i just put that down to pregnancy,as it was in both breasta)& lump is just in the left breast.

Hi,the lump does feel fixed and possibly non-movable?there are no skin changes on breasts that i've noticed.
As i said i was 6 weeks pregnant but miscarried 9 days ago,,,so are horemones involved,but was very early in pregnancy so dont kno if they would possibly cause the lumpy fibroglandular breast tissue(which is what ultrasound showed this probably is)
if i have dense left breast,then i dont kno that a mammogram would help.as i've heard they arent good at detecting things on dense breats and ultra sound is best to investigate a lump that is palpable....or so i've read on here.

Hi.

Lumps in the breast can have both benign and malignant causes, with the incidence of the former farther outweighing the incidence of the latter.  For your age, fibroadenomas and fibrocystic breast disease is still a common occurrence and this is usually associated with hormonal stimulation of the breast tissues.  There are lump characteristics that can point out to a possible malignancy such as fixed, non-movable lumps, irregular or gritty borders, or if the lump is associated with a skin dimple.  If these are absent, and your doctors suspect the lump to be benign, then it may be reasonable to just follow up these lesions.

I would suggest that you ask your doctors about a mammogram since the appearance of the breast lumps on this test would give us a clue on whether it is most likely benign or malignant.
