My mom's sister found a lump in her breast and it turned out to be a benign fatty cyst. On the other end of the spectrum, my dad's sister found one and it turned out to be cancer. She had radiation and chemotherapy and the cancer is officially in remission. I guess they got it early enough or it was a less aggressive form than others.

Some women just naturally have lumps and bumps in their breast tissue, so it's important to always do regular self exams so you know what's normal and what's not.

Good luck and fingers crossed that its nothing serious.
