Small lump on breast, on HRT and worried

Hi all! 

im new the this forum but been following all you lovely peoples chats the last week. 

I'm 29 and currently going through an induced menopause and taking HRT due to endometriosis. In May I noticed I have a small hard lump inbertween my breast and my armpit which at first I put down to being a bone (silly really but I'm really boney) 

couple of weeks ago I went GP and they did a fast referral to the breast centre where I saw a consultant who then did an ultrasound and confirmed that my lump wasn't a cyst and they needed to do a biopsy to test further. 

The consultant said to me it's only small and it's not got aggressive edges - has anyone had that said to them before and then got the all clear from results? 

I get my results back on Thursday 15th and I'm so nervous, I have an 18 month year old and my health isn't the best anyway so I'm just in pure panic and I'm not sleeping or eating due to me overthinking. 

ive been reading a lot on HRT and the side affects too and this seems to be linked to breast cancer according to my friend Google (I have been trying to avoid but it's hard not too on sleepless nights)

has anyone gone through similar as I would love to chat so I can rant to someone other than my poor partner who is worrying himself xx
