About 5 years ago my dr found a tiny lump in one of my breasts (I got her to do a breast check for me) - I had to go and have an ultrasound to check it out.
I must say, the time between the find and the ultrasound results was the most nerve-wracking of my life. It was all I could think of.
Thank God, it/they (3 of them, as it turned out) were just tiny cysts that were absolutely nothing.
I truly hope that it's the same result for you too
