Hi, I'm 19 and I have a lump in my left breast and it came up a few days before my cycle started and was really painful when touched. I didn't really think much of it at the time because my breasts tend to get very sore and lumpy feeling before and during my cycle. But it has been about 3 weeks now and the lump is still there. It is not really painful anymore though. I worked at a camp last month and I drank coffee everyday sometimes twice a day and I used to not drink caffeine really at all. I was wondering if this could be a cyst or FBD or worse? My mom and her sister have FBD.

Also, my aunt is a nurse practitioner and she told me that from camp I have pulled muscles in my arm and in the upper breast/armpit area and that I seem to have swollen nerves in the area as well. Maybe this has something to do with it?

And, I missed my cycle last month. Which I feel like was stress related.

I am just scared my dad's sister had breast cancer so I am a bit worried.

Thanks!
