When I had my annual female exam, my doctor found a breast nodule in my breast. The first thing I had done was a mammogram. It had been almost a year since my last mammogram, and that one had been completely normal.
After this I was schedule for a biopsy. At this point I needed to decide if I was just going to have a biopsy done or have a lumpectomy as well.
They did not think it was cancer, so I decided to just have the biopsy done and go from there. They did put a small marker in my breast where the biopsy was done so this would easily show up on future mammograms.
Thankfully the results were benign and they said this type of lump would never turn in to cancer.
If you ever find something like this, don't put off going to the doctor to have it checked out. I was fortunate that it was nothing serious, but you never know until you are thoroughly checked out.
