Hi! Just wanted to talk to someone that knows a little about this subject! This will be a long one 
Having some issues around one breast which on their own wouldn’t annoy me but together have really got me worrying. Firstly I had a small pimple like lump on my breast, this hasn’t changed or went away in over 6 months now, I got that checked a good few months ago and my doctor didn’t think it was anything to worry about (on the skin). More recently, about 2 months ago I noticed a small dark brown circle on my nipple, which may just be a new mole (it does look like one) and just under a month ago I found a small lump under my arm (smaller than a pea). Neither of these have changed and I’m seeing my doctor on Monday to show them to her. I do check my breasts and haven’t felt any lumps within the tissue apart from what I’ve described above.
I’m just 23 but I am overweight.
I’m not really sure what I’m here for, I guess if anyone had any thoughts on my symptoms it would be great to hear. I’m just stressing out about the possible outcomes.
